Abstract:
Business process collaboration between independent parties is challenging when participants do not completely trust each other. Tracking actions and enforcing the activity authorizations of participants via blockchain-hosted smart contracts is an emerging solution to this lack of trust, with most state-of-the-art approaches generating the orchestrating smart contract logic from Business Process Model and Notation (BPMN) models. However, compared to centralized business process orchestration services, smart contract state typically leaks potentially sensitive information about the state of the collaboration, limiting the applicability of decentralized process orchestration. This paper presents a novel, collaboration confidentiality-preserving approach where the process orchestrator smart contract only stores encrypted and hashed process states and validates participant actions against a BPMN model using zero-knowledge proofs. We cover a subset of BPMN, which is sufficient from the practical point of view, support messagepassing between participants, and provide an open-source, endto-end prototype implementation that automatically generates the key software artifacts.

Abstract:
A web service composition is considered as a real revolution in SOA (Service Oriented Architecture). It is based on assembling independent and loosely coupled services to build a composed web service. This composition can be described from both a local or a global perspective by respective orchestration or choreography. The validation of web service orchestrations is the main topic of this work. It is based on the verification of two classes of properties: generic and specific properties. The former can be checked for any invoked web services whereas the specific properties are different interdependence relationships between activities within an orchestration process. These properties cannot be directly verified on the orchestration process, so, the authors have to use formal techniques. In this paper, they propose a formal approach for the validation of web service orchestrations. This work adopts WS-BPEL 2.0 as the language to describe the web service orchestration and uses the SPIN model-checker for the verification engine. The WS-BPEL specification is translated into Promela code which is the input language for the SPIN model-checker, in order to check generic and specific properties expressed with LTL (Linear Temporal Logic).

Abstract:
If nineteenth-century aesthetics distinguish between distinct, colourful French instrumentation and doubled, equalised German orchestration, this distinction softens when the ‘New German’ orchestration of Wagner and Strauss exploits individual instrumental colours before dissolving them into massive orchestral sonorities. Similarly, if early French electroacoustic music counteracts the meta-serialism of early twentieth-century German electronic music, Pierre Schaeffer's Traité des objets musicaux combines his early anecdotal Noise Studies with a noise-reduction process into a new, rather German aesthetic of electroacoustics. In search of musical objects through a reductive, analytical listening (entendre), Schaeffer's neutralisation of anecdotal noises into musical objects is analogous to New German orchestration's neutralisation of individual orchestral colours in order to synthesise new orchestral combinations. Although this orchestral synthesis is different from the analytical probe for new valeurs involved in entendre, the separation of the noise from its residual signification are fundamental processes within both nineteenth-century orchestrational and twentieth-century electroacoustic musical aesthetics. If our current understanding of electronic music aligns Schaeffer and Pierre Henry wholly with modernity and its putatively radical and self-conscious break with Berlioz, Brahms and historical tradition, this article suggests that an essential underlying continuity in the French-instrumentation/German-orchestration binary persists even in the face of the decline of the musical and cultural traditions that created and sustained them.

Abstract:
This article introduces the concept of orchestration as the mobilization of an intermediary by an orchestrator on a voluntary basis in pursuit of a joint governance goal. Orchestrator-Intermediary theory then provides a model of indirect governance that supplements delegation models premised on principal-agent theory. Under both theories, governors enhance their governance capacity by drawing on the capabilities of third parties. Whereas delegation is premised on hard ‘contractual’ control over the agent, however, orchestration relies on the soft control of like-minded intermediaries through material and ideational support. The two models overlap, and governors mix them in practice, but distinguishing between them analytically can broaden and deepen analysis of indirect forms of governance. This article discusses the circumstances under which each model provides a better fit for real-world problems, as well as the key limitations of each model. Among other things, orchestration is relatively more likely in democratic than authoritarian systems, when governors have limited direct capacities of their own and when veto players are more numerous. Orchestration is not always more desirable than delegation, but it provides an important alternative in some circumstances. Multiple examples from both domestic and international settings are used to illustrate this claim. The article closes with key considerations regarding the effectiveness and legitimacy of orchestration.

"Effectiveness of Segment Routing Technology in Reducing the Bandwidth and Cloud Resources Provisioning Times in Network Function Virtualization Architectures."

Abstract:
Network Function Virtualization is a new technology allowing for a elastic cloud and bandwidth resource allocation. The technology requires an orchestrator whose role is the service and resource orchestration. It receives service requests, each one characterized by a Service Function Chain, which is a set of service functions to be executed according to a given order. It implements an algorithm for deciding where both to allocate the cloud and bandwidth resources and to route the SFCs. In a traditional orchestration algorithm, the orchestrator has a detailed knowledge of the cloud and network infrastructures and that can lead to high computational complexity of the SFC Routing and Cloud and Bandwidth resource Allocation (SRCBA) algorithm. In this paper, we propose and evaluate the effectiveness of a scalable orchestration architecture inherited by the one proposed within the European Telecommunications Standards Institute (ETSI) and based on the functional separation of an NFV orchestrator in Resource Orchestrator (RO) and Network Service Orchestrator (NSO). Each cloud domain is equipped with an RO whose task is to provide a simple and abstract representation of the cloud infrastructure. These representations are notified of the NSO that can apply a simplified and less complex SRCBA algorithm. In addition, we show how the segment routing technology can help to simplify the SFC routing by means of an effective addressing of the service functions. The scalable orchestration solution has been investigated and compared to the one of a traditional orchestrator in some network scenarios and varying the number of cloud domains. We have verified that the execution time of the SRCBA algorithm can be drastically reduced without degrading the performance in terms of cloud and bandwidth resource costs.

Abstract:
This paper shows a flexible orchestration solution for deploying Cooperative, Connected, and Automated Mobility (CCAM) services in 5G and beyond networks. This solution is based on the concepts of federation and hierarchy of orchestration functions. The federated approach is leveraged to cope with the differentiated complexity operation when multiple network operators are considered, whereas the hierarchical approach addresses the issue of jointly orchestrating multiple edge platforms in the network of a single operator. In this complex orchestration architecture, the main contribution of this paper consists of the design and implementation of an Abstraction and Adaptation Layer (AAL) for edge clouds, a new component enabling a truly cooperative and coordinated orchestration between different edge systems, characterized by appreciable experimental performance in terms of latency.

Abstract:
Orchestrating collaborative learning activities is a challenge, even with the support of technology. Tangibles as orchestration tools represent an ambient and embodied approach to sharing information about the learning content and flow of the activity, thus facilitating both collaboration and its orchestration. Therefore, we propose tangibles as a solution to orchestrate productive collaborative learning. Concretely, this paper makes three contributions toward this end: First, we analyze the design space for tangibles as an orchestration tool to support collaborative learning and identify twelve essential dimensions. Second, we present five tangible tools for collaborative learning activities in face-to-face and online classrooms. Third, we present principles and challenges to designing tangibles for orchestrating collaborative learning based on our findings from the evaluation of ten educational experts who evaluated these tools using a usability scale and open questions. The key findings were: (1) they had good usability; (2) their main advantages are ease of use and support for collaborative learning; (3) their main disadvantages are limited functions and the difficulty to scale them to more users. We conclude by providing reflections and recommendations for the future design of tangibles for orchestration.

Abstract:
Container virtualization technology facilitates the creation of microservices-based systems through continuous integration. Container-based apps can be deployed more easily when they use orchestration systems like Kubernetes, which has become the de facto standard. It can be difficult to create effective and precise orchestration systems, nevertheless. The scheduler, a crucial orchestrator task that allocates physical resources to containers, is the subject of this article. Scheduling strategies are developed using several Quality-of-Service metrics. The CI in CI/CD stands for continuous integration. Continuous integration drives the automation in the development and delivery of the code and developers frequently apply code changes. It’s an automated process that allows multiple developers to contribute software components to the same project without integration conflicts. CI also triggers the process of testing the applications automatically upon code commit into the repository.

Abstract:
This paper discusses the trajectory of the instrumental meta-orchestration model (IMO) development, studies and results, and extensions. Instrumental meta-orchestration, developed as a solution for teacher training on instrumental orchestration (IO), relied on its development of concepts such as meta-situation, didactic meta-configuration, and meta-exploration model. An experimental study with its analysis led to the development of data visualisation instruments in an internal analysis context at the IO. These concepts and analysis instruments were used in research that followed that of the IMO, such as the extension of the IMO to interdisciplinary teachers’ education. The concepts of ad hoc reaction, artefacts such as didactic webdoc, and analysis of events between orchestrations show their potential and subsidise new research for teacher training in integrating digital technologies.

Abstract:
Platform as a Service (PaaS) has produced a huge impact on how we can offer easy and scalable software that adapts to the needs of the users. This has allowed the possibility of systems being capable to easily configure themselves upon the demand of the customers. Based on these features, a large interest has emerged to try and offer virtualized Hadoop solutions based on Infrastructure as a Service (IaaS) architectures in order to easily deploy completely functional Hadoop clusters in platforms like Amazon EC2 or OpenStack. Throughout the thesis work, it was studied the possibility of enhancing the capabilities of KTHFS, a modified Hadoop platform in development; to allow automatic configuration of a whole functional cluster on IaaS platforms. In order to achieve this, we will study different proposals of similar PaaS platforms from companies like VMWare or Amazon EC2 and analyze existing node orchestration techniques to configure nodes in cloud providers like Amazon or Openstack and later on automatize this process. This will be the starting point for this work, which will lead to the development of our own orchestration language for KTHFS and two artifacts (i) a simple Web Portal to launch the KTHFS Dashboard in the supported IaaS platforms, (ii) an integrated component in the Dashboard in charge of analyzing a cluster definition file, and initializing the configuration and deployment of a cluster using Chef. Lastly, we discover new issues related to scalability and performance when integrating the new components to the Dashboard. This will force us to analyze solutions in order to optimize the performance of our deployment architecture. This will allow us to reduce the deployment time by introducing a few modifications in the architecture. Finally, we will conclude with some few words about the on-going and future work.

Abstract:
In the modern era there is a big change in the way computer networks are conceived and the old version defined by hardware implementation is leaving space for a new one based upon software functions. This innovation is the Network Function Virtualization and indeed aims at easing the management of networks and reducing the costs of their maintenance by deploying Virtual Network Functions in standard general purpose servers. The transition to this solution involved the necessity to improve the performance of virtualization techniques and with the development of new solutions now it is possible to run multiple different functions in the same physical machine. This means that also the cloud computing benefits from this technology, having computing, storaging and networking resources all easily manageable and accessible due to their separation from the hardware underneath. Therefore it is important that while building this architecture the components are properly working and interacting together and that the virtualization techniques do not produce too much overhead compared to the performance of the hardware implementation. In this essay will be discussed the Network Function Virtualization and the Open Source MANO project, focusing on its descriptors architecture and functioning. To better demonstrate how to create network topologies through these files, some examples are created and analyzed.

Abstract:

Network collaboration between industrial enterprises is the main topic in this dissertation. My aim has been to explore if it is possible to construct a network between industrial enterprises, which for the participating enterprises represents a valuable asset in order to become more innovative, increasing their competitive power. The dissertation contains an overarching umbrella paper and six ordinary papers.

The construction of a network consisting of a set of enterprises, calls for contributions in the field from outsiders, such as researchers. Thus, in my study I have used an action research approach, interpreted as the researcher operating as a ‘friendly outsider’ in the network. To be able to enter into problem solving together with local practitioners calls for a longitudinal approach, meaning that the researcher collaborates closely with the network and the enterprises for a long period of time.

The research process that I have made use of in my study is divided into two closely linked parts. Firstly, I have been part of a network construction and maintenance process for more than four years, establishing sustainable networking processes. The experiences coming from these processes represent my empirical data. Secondly, I have reflected individually, and participated in joint reflection with actors in the research field over experiences and the results of the actions taken in the network. These reflections have resulted in the writing of six papers that are part of this dissertation. In these papers, I have discussed what I regard as the most important elements to arrange for network collaboration and networking processes.

My ambition with the umbrella paper is to pull the different elements discussed in the different papers together in order to present a dynamic networking model. Thus, the model developed is a result of my research on several networks of industrial enterprises. However, the model is not meant to be a definite recipe for constructing additional networks. I regard networks as socially constructed, and as such, they are the result of processes that involve human participation. The personnel involved have their own mental models that will heavily influence the construction and operation of a network. Thus, the model can be used to merely interpret the importance of the existence of a set of enablers while constructing or operating network processes.

The model consists of a set of enablers identified through the research process in this study, and they are thoroughly discussed in the different papers as well as in the umbrella. These enablers are:

• Training. This is an important enabler that may increase knowledge about development work and processes, and the diffusion of such knowledge.

• Network management. Taking care of the daily operation, and closely linked to the enterprises, network management is important in initiating and supporting networking processes.

• Processing roles. Personnel able to hold such roles are important for initiating and accomplishing networking processes, as well as for the supply of external knowledge, funding, and general support.Introducing this as an enabler implies, most likely, making it easier for external resources to assist in operating the networking processes.

• Network infrastructure. The existence of a network structure that makes it possible for the enterprises to discuss experiences and ideas and to develop knowledge is vital. In Paper V, which is a comparison of networks in Sweden and Norway, the management of the network has been analysed and the most striking discovery is the solid structures that are constructed.

• Leadership. The management and unions in the participating enterprises need to take leadership to allow for networking processes to occur. The role of unions in legitimating wide employee involvement seems to be especially important.

As I have indicated, the above enablers or instruments, acting differently, are needed to construct sustainable networking processes. Such processes may bring about important innovations or developments for individuals or groups of enterprises, as shown in several of my papers. Individually, the instruments may be good and important, but they may become even better when combined with other instruments. My study indicates that the support given to network processes by combining instruments may increase what the individual instrument can offer. Thus, orchestration of instruments appears as an important and valuable coordination of contributions given to such processes. Thus, I have revealed that the presence of a number of enablers is necessary to establish sustainable networking processes, but these enablers are not sufficient to get these processes going. As I have shown, orchestration is also needed to initiate and continue such processes, and it calls for action researchers who possess skills and knowledge that enable them to serve as orchestrators.

Abstract:
Computer networks are continuously evolving and growing in size and complexity. New technologies are being introduced which further increases the complexity. Net- work Service Orchestration is all about pushing configuration out into the network devices automatically without human intervention. There can be issues that causes the orchestration to fail. In many cases manual operations must be done to recover from the error which is very contradicting since the goal of orchestration is that it should be fully automated. There is some indication that the errors that are being solved manually could be de- tected and handled by a feedback mechanism. This thesis work aimed to build on current insight and if possible, verify that the feedback mechanism is a viable method. After consideration on different ways to solve the research question, the choice fell on creating a test environment where the approach was tested. The test environment was used to investigate if a network orchestration system could be integrated with a feedback mechanism. The result of this project presents a way to automatically de- tect a network failure and send feedback to a Network Service Orchestrator. The or- chestrator is then able to identify and correct the error.
Datornätverk utvecklas kontinuerligt och växer i storlek och komplexitet. Nyteknik införs som ytterligare ökar komplexiteten. Nätverksservice orkestrering handlar om att skicka ut konfiguration automatiskt till enheter i nätverket utan mänsklig in- blandning. Det kan finnas problem som gör att orkestreringen misslyckas. I många fall måste manuella åtgärder utföras för att lösa problemet, vilket är mycket motsä- gelsefullt, eftersom målet med orkestrering är att det ska vara fullt automatiserat. Det finns indikationer på att fel kan detekteras och hanteras av en återkopplings- mekanismen. Detta examensarbete syftar till att bygga på aktuell insikt, och om möj- ligt, verifiera att återkopplingsmekanismen är en möjlig metod. Efter överväganden på vilka olika sätt som projektmålet kunde uppnås föll valet på att skapa en testmiljö där ansatsen kunde testas. Testmiljön användes för att utreda om ett nätverksorkestreringssystem kan integreras med en återkopplings mekanism. Resultat av projektet presenterar ett sätt att automatiskt upptäcka ett nätverksfel och skicka återkoppling till ett nätverksorkestreringssystem. Nätverksorkestreraren kan sedan detektera och åtgärda felet.

Abstract:
L’apprentissage mobile est devenu un sujet d’intérêt car il implique de nombreux domaines de recherche concernant les contextes d’usages et de technologie complexes. En effet, ce type de formation a été reconnu pour sa capacité à motiver les apprenants car ils peuvent construire leurs propres connaissances en collaborant avec les autres. Dans ce contexte, l’orchestration des scénarios d'apprentissage mobile permet la gestion en temps réel et la contextualisation des activités à réaliser mais ceci engendre des coûts importants d’organisation. En outre, cette organisation réalisée par l'instructeur est peu adaptée aux méthodes d’apprentissage employées pendant la sortie pédagogique car l’apprenant doit pouvoir garder une certaine maîtrise de ses choix et de son parcours. Dans cette thèse, nous présentons un nouveau style de recommandation pour faire une orchestration dynamique des activités d’apprentissage en fonction de la localisation des apprenants et de l’historique de la visite. Cette technique s’appuie sur un filtrage collaboratif exploitant l’activité antérieure des apprenants mais en prenant en compte les contraintes pédagogiques et la localisation. Notre approche s’inspire du mode de fonctionnement de l’intelligence en essaim (algorithme ACO) pour l’implémentation de notre système de recommandation des POIs. Outre les simulations qui ont permis de comparer les différentes variantes de recommandations, la validation de notre système SAMSSP passe par l’expérimentation de nos deux prototypes de visite de campus
Mobile learning has become a topic of interest because it involves many areas of research concerning usage contexts and complex technology. Indeed, mobile learning is has been recognized for its ability to motivate learners because they can construct their own knowledge by collaborating with others. In this context, the orchestration of mobile learning allows real-time management and contextualization of activities to do but this results in significant costs of organization. In addition, centralized orchestration is not adapted to the context of our mobile scenario because the learner must be able to keep some control over their choices of learning.In this thesis, we present a new style of recommendation for a dynamic orchestration of learning activities based on the location of the learners and the history of the visit. This technique is based on a collaborative filtering that exploits prior activity of the learners and that respects the educational and location constraints. Our approach is based on the mode of operation of the Swarm Intelligence (ACO algorithm) for the implementation of our system of recommendation. Besides the simulations that are used to compare the different variants of recommendations, the validation of the SAMSSP system goes through the experimentation of the two prototypes of campus visit

Abstract:
Ce travail de thèse a pour objectif la définition d'une plate-forme logicielle pour l'interprétation d'orchestrations sur un cluster de bus logiciels. Nous proposons une approche qui permet d'offrir une haute disponibilité et une transparence d'utilisation aux usagers. Cette approche est dirigée par des modèles MDA où chaque niveau de modélisation est atteint après enrichissement de notre architecture avec des informations supplémentaires. Chaque enrichissement est défini comme une transformation entre deux niveaux adjacents. Notre premier niveau CIM se présente comme des spécifications formelles écrites en π-calcul polyadique d'ordre supérieur qui fournissent une définition formelle d'une architecture logicielle pour l'interprétation d'orchestration. Tout système distribué bâti sur cette architecture est capable d'interpréter différents types d'orchestrations de manière parallèle. Nos spécifications sont fortement inspirées du modèle classique bus logiciel, il décrit une architecture fortement modulable qui s'adapte au nombre d'orchestrations à traiter et au nombre de clients qui veulent accéder à ces orchestrations. Notre deuxième niveau PIM nous permet de définir un langage que nous avons baptisé π-DSL qui est un langage dédié aux orchestrations. Il introduit la notion de migration d'orchestrations au système de composition d'orchestration EIP défini par Gregor Hohpe. Le langage que nous définissons à ce niveau est dédié au domaine des orchestrations et permet de construire des orchestrations de façon simple et intuitive. Notre troisième niveau PSM nous permet d'enrichir le niveau précèdent en associant les concepts formels aux implantations concrètes. A ce niveau, nous introduisons des frameworks tels que les conteneurs OSGi, l'outil d'intégration de service Apache Camel ou bien le référentiel de code exécutable Apache Archiva. Ces frameworks sont enrichis dans le cadre de notre implantation afin qu'ils soient fidèles aux spécifications établies dans les niveaux supérieurs. Notre quatrième est dernier niveau est le niveau ISM qui présente le contexte d'exécution de l'architecture proposée. Il est obtenu en ajoutant des informations relatives à chaque outil. Nous avons transformé nos spécifications formelles définies en π-calcul d'ordre supérieur vers un réseau d'automates temporisés La définition complète des transformations d'une spécification à base d'EIP est une autre contribution de cette thèse. Ceci nous conduit à réaliser la transformation de notre spécification π-calcul dans le but de tendre vers une implémentation. Nous nous sommes intéressés à 2 types de propriétés liées à notre architecture : la transparence de localisation, la transparence d'échelle. Ces propriétés sont établies en utilisant notre réseau d'automates temporisés et avec l'emploi d'un outil reconnu dans le monde de la preuve par model-checking, l'outil UppAal. Ainsi, nous validons la possibilité d'établir des propriétés liées à la mobilité de code via un réseau d'automates. Dans le cadre de notre implantation, nous avons adapté les frameworks définis dans le cadre de notre PSM afin qu'ils respectent la modélisation formelle réalisée dans la première partie de cette thèse. Nous proposons aussi des outils en vue de l'édition. Ces outils couvrent tout le cycle de vie de l'architecture proposée. Notre framework d'interprétation apporte les transparences décrites dans nos modèles auxquelles s'ajoutent de nouvelles propriétés de transparences provenant de nos choix de réalisation. Pour mesurer le coût de la migration sur les orchestrations durant l'évaluation de notre framework nous utilisons SoapUI comme outil de mesure. Pour réduire au maximum les effets des perturbations sur le code source des différentes orchestrations, nous avons développé nos propres outils de mesure. Nos tests portent sur un comparateur de prix car il représente un scénario classique de benchmarking utilisé par d'autres frameworks d'orchestrations
This thesis aims to define a software platform for the interpretation of orchestrations on a cluster of ESBs. We propose an approach to provide high availability and transparency to users. This approach is model driven, where each modeling level is reached after enrichment of our architecture with additional information. Each enrichment is defined as a transformation between two adjacent levels. Our first level (CIM) is written as formal specifications in polyadic higher-order π-calculus that provide a formal definition of the software architecture that is used for the interpretation of orchestration. Any distributed system built on this architecture is able to interpret different types of orchestrations in parallel. Our specifications are based in traditional software model bus, it describes a highly scalable architecture that adapts to the count of orchestrations to be treated and the count of customers who want to access these orchestrations. Thus, location transparency, transparency of scale or the access transparency are enhanced through the specification of π-calculus terms. Our second level (PIM) allows us to define a language that we call π-DSL, this is a language dedicated to the orchestrations. It introduces the concept of migration of orchestrations system build on orchestration based on EIP composition defined by Gregor Hohpe. At this level, we define this language dedicated to the domain of orchestrations and helps build orchestrations in a simple and intuitive way. Our third level (PSM) enables us to enrich the previous level combining formal concepts to practical implementations. At this level, we introduce frameworks such as OSGi containers, the integration of Apache Camel Service or the Apache Archiva tool as repository of executable code. These frameworks are enhanced as part of our transformation, so they are compatible to the specifications laid down in the upper levels. The fourth and the last level (ISM) provides the executions context of the proposed architecture. It is obtained by adding information about each tool. This level represents the culmination of the MDA that we adopt in the context of our approach. We turned our formal specifications defined in higher order π-calculus to a network of timed automata. The definition of the complete transformation of an EIP based specification is another contribution of this thesis. Indeed, in order to automate our approach, we focused on the specification of the platform but also in the interpretation tools. This leads us to realize the transformation of our π-calculus specification in order to move towards an implementation. We are interested in two types of architecture related to our properties : Location transparency; Scale transparency. These properties are established using our network of timed automata and the use of a globally recognized proof using UppAal model-checking tool. Thus, we validate the feasibility of proofing the properties related to the mobility of code via a network of automata. As part of our implementation, we have adapted defined frameworks in our ISM in order to respect the formal modeling defined in the first part of this thesis. We also offer tools for editing, processing and the interpretation of orchestration in a distributed heterogeneous environment. These tools cover the entire life cycle of the proposed architecture. Our interpretation framework provides transparencies described in our models plus new properties transparencies from our implementation choices. To measure the cost of the migration of orchestrations during the evaluation of our framework, we use SoapUI as a measurement tool that interfaces with orchestrations by a web services interface. To minimize the effects of disturbances on the source code of different orchestrations, we have developed our own measurement tools

Abstract:
We develop a novel approach for run-time global adaptation of microservice applications, based on synthesis of architecture-level reconfiguration orchestrations. In particular, we devise an algorithm for automatic reconfiguration that reaches a target system maximum computational load by performing optimal deployment orchestrations. To present our approach we use the high-level object-oriented probabilistic/timed specification language Abstract Behavioral Specification (ABS).With ABS we model microservice applications and virtual machines, we synthesize deployment orchestrations and we simulate them. In particular, we conceive the orchestration language time model so to encompass: microservice deployment time and virtual machine speed based on cpu cores that are actually being used. We evaluate the applicability of our approach on a realistic microservice application taken from the literature: an Email Pipeline Processing System. We show its effectiveness by simulating such an application and by comparing architecture-level reconfiguration with traditional local scaling techniques (detecting scaling needs and enacting replications at the level of single microservices). Our comparison results show that our approach avoids cascading slowdowns and consequent increased message loss and latency that affect traditional local scaling.

Abstract:
Cloud applications and services are frequently built using multiple tiers and current trends such as micro-services further increase componentization, allowing us to place each component in a different physical machine in a distributed cloud. Ericsson owns and manages very large networks, which offer diverse infrastructure in terms of computational power, storage but most importantly position in the network. Typically, a machine which is closer to the edge of the network (closer to the end user) will have limited resources but it will offer less latency, for a higher price. At the same time, several enterprise/industrial areas expect to benefit from the cloud business model in a large-scale distributed environment. These types of applications have very diverse end-2-end Service-Level Agreements (SLA) to be fulfilled, while at the same time the cloud environment needs to optimize processing, storage, and networking costs. Moreover, customers might want to change and adjust SLAs/requirements themselves using selfmanagement portals. The objective of this project is to model the network and services offered by Ericsson. Then, given the SLA, finding a valid solution of the problem, using a constraint solver. A solution is a set of physical machines that host the components the required service is composed from. This approach has many challenges since the same service can be composed from different sets of components. The connected components form a connectivity graph, where nodes in the graph are connected by physical links. But, since the connection is described by higher level components (composed by simpler components), this graph can also be expressed as a tree. Leaves in the tree are the nodes that compose the higher-level services and the ones that must be hosted in the infrastructure. The characteristics of each leaf-node depend on its parent and/or siblings in the component tree. Finally, since the components are normally connected, the physical connection between nodes in the network must be taken into consideration. The proposed model is evaluated in several cases, in order to identify how the number of the software components and the infrastructure topology affect the solution finding. The results are promising, showing fast resolution of the problem instances, varying for each test case, from a few seconds to a couple of minutes.
Molnapplikationer och tjänster är ofta byggda med flera nivåer och nuvarande trender såsom mikro-tjänster ökar ytterligare komponentiseringen, vilket tillåter oss att placera varje komponent i en annan fysisk maskin på ett distribuerat moln. Ericsson äger och förvaltar väldigt stora nätverk som erbjuder varierande infrastruktur när det gäller beräkningskraft , lagring och framför allt position i nätverket. Typiskt kommer en maskin som är närmare kanten av nätet (närmare slutanvändaren) att ha begränsade resurser, men det kommer att erbjuda mindre latens till ett högre pris. Samtidigt räknar flera företag / industriområden med att dra nytta av moln affärsmodelltjänster i en storskalig och distribuerad miljö. Den här typen av applikationer har väldigt olika end-to-end varierande servicenivåavtal (SLA) som skall uppfyllas, medan moln miljön behöver optimera bearbetnings, lagrings och nätverks kostnader. Dessutom, kan kunden komma att vilja ändra och justera SLA / krav själva med hjälp av självhantering portaler. Målet för detta projekt är att modellera nät och tjänster som erbjuds av Ericsson. Sedan, givet ett SLA, att hitta en giltig lösning på problemet, med hjälp av en villkorslösare. En lösning är en uppsättning av fysiska maskiner som är värdar för komponenterna från vilka den efterfrågade tjänsten är sammansatt. Detta tillvägagångssätt är förenat med många utmaningar eftersom samma tjänst kan bestå av olika uppsättningar av komponenter. De anslutna komponenterna bildar ett förbindelseschema, där noder i grafen är anslutna med fysiska länkar. Men eftersom anslutningen beskrivs av komponenter högre nivå (bestående av enklare komponenter), denna graf kan också uttryckas som ett träd. Löv i trädet är noderna som utgör de högre nivå tjänster och de som måste finnas i infrastrukturen. Egenskaperna hos varje löv-nod att bero på dess förälder och / eller syskon i komponentträdet. Slutligen, eftersom komponenterna i normal fall är anslutna, måste den fysiska anslutningen mellan noder i nätet tas i beaktande. Den föreslagna modellen utvärderas i flera fall, för att identifiera hur antalet programvarukomponenter och infrastrukturens topologi påverkar resultatet av lösningen. Resultaten är lovande och visar snabb lösning av problemets instanser, varierande för varje testfall, från några sekunder till ett par minuter.

Abstract:
Evolving 5G network scenarios will have to deal with new multiple administrative domain (aka multi-domain) orchestration models. Based on a new broker-plane approach on top of per-domain management and orchestration functions, we present a Multi-domain orchestration prototype capable to coordinate the delivery of a multi-operator End-to-End Network Service (E2ENS) that combines per-domain paths and network functions for a given service request. Our prototype implementation retrieves local information about topology and resources from each Multi-domain Orchestrator (MdO) to offer after inter-domain added value services in the form of abstract Map Services. These map abstractions are easily consumable through developer-friendly REST APIs based on the Application-Layer Traffic Optimization (ALTO) standard protocol.

Abstract:
[Executive summary] Literacy studies have traditionally focussed on the seen. The other senses are typically under-recognised in literacy studies and research, where the visual sense has been previously prioritised. However, spoken and written language, images, gestures, touch, movement, and sound are part of everyday literacy practices. Communication is no longer focussed on visual texts but is a multisensory experience. Effective communication depends then on sensory orchestration, which unifies the body and its senses. Understanding sensory orchestration is crucial to literacy learning in the 21st century where the combination of multisensory practices is both digital and multimodal. Unfortunately, while multimodal literacy has become an increasing focus in school curriculum, research has still largely remained focussed on the visual. The Sensory Orchestration for Multimodal Literacy Learning in Primary Education project, led by ARC Future Fellow Professor Kathy Mills, sought to address this research deficit. In addressing this gap, the project built an evidence base for understanding how students become critical users of sensory techniques to communicate through digital, virtual, and augmented-reality texts. The project has contributed to the development of new multimodal literacy programs and a next-generation approach to multimodality through the utilisation of innovative sensorial education programs in various educational environments including primary schools, digital labs, and art museums.

Abstract:
Unfolding processes of timbre and memory in improvisational piano performance This exposition is an introduction to my research and practice as a pianist, in which I unfold processes of timbre and memory in improvised music from a performer’s perspective. Timbre is often understood as a purely sonic perceptual phenomenon. However, this is not in accordance with a site-specific improvisational practice with changing spatial circumstances impacting the listening experience, nor does it take into account the agency of the instrument and objects used or the performer’s movements and gestures. In my practice, I have found a concept as part of the creating process in improvised music which has compelling potential: Timbre orchestration. My research takes the many and complex aspects of a performance environment into account and offers an extended understanding of timbre, which embraces spatial, material and bodily aspects of sound in improvised music performance. The investigative projects described in this exposition offer a methodology to explore timbral improvisational processes integrated into my practice, which is further extended through collaborations with sound engineers, an instrument builder and a choreographer: -experiments in amplification and recording, resulting in Memory piece, a series of works for amplified piano and multichannel playback - Piano mapping, a performance approach, with a custom-built device for live spatialization as means to expand and deepen spatio-timbral relationships; - Accretion, a project with choreographer Toby Kassell for three grand pianos and a pianist, where gestural approaches are used to activate and compose timbre in space. Together, the projects explore memory as a structural, reflective and performative tool and the creation of performing and listening modes as integrated parts of timbre orchestration. Orchestration and choreography of timbre turn into an open and hybrid compositional approach, which can be applied to various contexts, engaging with dynamic relationships and re-configuring them.

Full text
Abstract:
Governance is a difficult task in the context of achieving landscape multifunctionality owing to the multiplicity of stakeholders, institutions, scale and ecosystem services: the ‘many-multiple’ (Cockburn et al 2018). Governing and managing the physical landscape and the actors in the landscape requires intensive knowledge and good planning systems. Land-use planning is a powerful instrument in landscape governance because it directly guides how actors will intervene in the physical landscape (land use) to gain commonly desired value. It is essential for sustaining rural landscapes and improving the livelihoods of rural communities (Bourgoin and Castella 2011, Bourgoin et al 2012, Rydin 1998), ensuring landscape multifunctionality (Nelson et al 2009, Reyers et al 2012) and enhancing efficiency in carbon sequestration, in particular (Bourgoin et al 2013, Cathcart et al 2007). It is also considered critical to the successful implementation of land-based climate mitigation, such as under Nationally Determined Contributions (NDCs), because the Land Use, Land-Use Change and Forestry (LULUCF) sector is included in the mitigation contributions of nearly 90 percent of countries in Sub-Saharan and Southern Asia countries and in the Latin American and Caribbean regions (FAO 2016). Viet Nam has been implementing its NDC, which includes forestry and land-based mitigation options under the LULUCF sector. The contribution of the sector to committed national emission reduction is significant and cost-effective compared with other sectors. In addition to achieving emission reduction targets, implementation of forestry and land-based mitigation options has the highest benefits for social-economic development and achieving the Sustainable Development Goals (MONRE 2020). Challenges, however, lie in the way national priorities and targets are translated into sub-national delivery plans and the way sub-national actors are brought together in orchestration (Hsu et al 2019) in a context where the legal framework for climate-change mitigation is elaborated at national rather than sub-national levels and coordination between government bodies and among stakeholders is generally ineffective (UNDP 2018). In many developing countries, conventional ‘top–down’, centralized land-use planning approaches have been widely practised, with very little success, a result of a lack of flexibility in adapting local peculiarities (Amler et al 1999, Ducourtieux et al 2005, Kauzeni et al 1993). In forest–agriculture mosaic landscapes, the fundamental question is how land-use planning can best conserve forest and agricultural land, both as sources of economic income and environmental services (O’Farrell and Anderson 2010). This paper provides guidance on monitoring integrated tree-based landscape management at commune level, based on the current legal framework related to natural resource management (land and forest) and the requirements of national green-growth development and assessment of land uses in two communes in Dien Bien and Son La provinces. The concept of integrated tree based landscape management in Viet Nam is still new and should be further developed for wider application across levels.

Abstract:
The Covid-19 pandemic has precipitated unprecedented health, social and economic crises across the countries of Latin America and the Caribbean. All countries in the region moved quickly to implement rescue policies to safeguard lives and livelihoods. The rescue phase continues along with the challenge of orchestrating the post-COVID-19 economic recovery: designing packages of investments and initiatives to stimulate employment, liquidity, reignite sustainable and inclusive economic growth and transition towards net-zero emission and climate-resilience economies to confront the worsening climate and ecological crisis. These policies must be sustainable in the short and long term and bring institutional, social, economic/financial, and environmental co-benefits. This working paper proposes criteria for evaluating the sustainability of recovery investments and initiatives, to serve as a checklist for stakeholders to use to ensure a recovery that builds an inclusive, sustainable and resilient future for all.
