Scientific applications require to process, analyze and transfer large volumes of data in the shortest possible time from distributed data sources. In order to improve their performance, it is necessary to provide them with specific QoS parameters. On the other hand, SDN is presented as a new paradigm of communications networks that facilitates the management of the communications infrastructure and consequently allows to dynamically incorporate QoS parameters to the applications running in this type of network. With both these paradigms in mind, we conducted this research to answer the following questions: Do scientific applications that are running in an SDN-Enabled distributed data centers improve their performance? Do they consider network QoS parameters for job scheduling? The methodology used was to consult articles in specialized databases containing the keywords SDN and for scientific applications: HPC and Big Data. Then, we analyzed the articles where these keywords intersect with some of the parameters related to QoS in communications networks. Also, we reviewed QoS proposals in SDN to identify the advances in this research area. The results of this paper are: i) QoS is an open issue to incorporate in scientific applications that are running in an SDN ii) we identified the challenges to join both these paradigms, and iii) we present a strategy to provide QoS to scientific applications that are being executed among SDN-Enabled distributed data centers.

As a new network paradigm, software-defined networks (SDN) are able to cope with the limitations of traditional networks. SDNs use a management controller with a global view of the network and switching devices that act as packet forwarding equipment, known as «OpenFlow switches». Network resources limitations and ensuring quality of service requirements lead to an important need for load balancing between SDN switches. The purpose of work research and analysis of load balancing processes in SDN based on genetic algorithm. To confirm the effectiveness and correctness of the genetic algorithm in SDN, the software for modeling the load balancing processes has been developed. The simulation results confirmed the efficiency of the genetic algorithm in SDN for balancing and redistributing network traffic in order to ensure the required quality of service and reduce network congestion.

Ожидается, что рост числа мобильных устройств и потребность в пользовательских данных к 2030 году окажут беспрецедентное давление на текущую мобильную сеть. У будущих мобильных сетей должно быть несколько требований в отношении объема данных, задержки, качества обслуживания и опыта, мобильности, спектра и энергоэффективности. Поэтому в последнее время начались усилия по созданию более эффективных решений для мобильных сетей. С этой целью балансировка нагрузки привлекла большое внимание как многообещающее решение для более эффективного использования ресурсов, повышения производительности системы и снижения эксплуатационных расходов. Это эффективный способ сбалансировать трафик и уменьшить перегрузку в гетерогенных сетях в будущих сетях 5G / IMT-2020. Балансировка нагрузки - одна из наиболее важных задач, необходимых для максимального повышения производительности, масштабируемости и надежности сети. В настоящее время с появлением программно-конфигурируемых сетей (SDN) балансировка нагрузки для SDN стала важной проблемой в будущей сети 5G / IMT-2020. SDN позволяет использовать программируемые балансировщики нагрузки и обеспечивает гибкость для разработки и реализации стратегий балансировки нагрузки. В этом обзоре мы выделяем методы балансировки нагрузки на основе сетей SDN и предполагаемые требования к балансировке нагрузки в сетях 5G The growing number of mobile devices and the demand for user data by 2030 are expected to put pressure on the current mobile network in an unprecedented way. Future mobile networks must have several requirements regarding data amount, latency, quality of service and experience, mobility, spectrum, and energy efficiency. Therefore, efforts have recently begun for more efficient mobile network solutions. To this end, load balancing has attracted much attention as a promising solution for greater resource utilization, improved system performance, and reduced operating costs. This is an effective way to balance traffic and reduce congestion in heterogeneous networks in future 5G/IMT-2020 networks. Load Balancing is one of the most critical tasks required to maximize network performance, scalability, and robustness. Nowadays, with the emergence of Software-Defined Networking (SDN), Load Balancing for SDN has become a significant issue in future network 5G/IMT-2020. SDN allows for programmable load balancers and provides the flexibility to design and implement load balancing strategies. In this survey, we highlight the methods of load balancing based on SDN networks and prospective load balancing requirements on 5G networks

Full textAbstract:
With the exponential growth of the Internet of Things (IoT) devices connected to the internet, resource provisioning for such the heterogeneous network is a challenging task for the traditional network architecture. In this context, the Software-Defined Networking (SDN) introduces many opportunities and provides the potential to overcome challenges associated with traditional network architecture. This work presents a Software-Defined IoT (SDIoT) architecture. The main focus of this research is to design a control plane (CP) for the SDIoT. The scope of this work is limited to the introduction of an overlay SDN CP in the traditional IoT network architecture. The proposed architecture focuses on resource provisioning while ensuring the quality of service (QoS) satisfaction for the network. A comparative analysis between the traditional and the SDN network approach was done in terms of Jitter, Latency and Throughput. From the latency, delay and throughput performance results, the SDN-based IoT network improves network efficiency by reducing network overheads generated from frequent communication between the nodes and the controllers. Precisely, the average latency and average jitter percentile improvement from the traditional IoT network to the SDIoT for all the nodes is 574% and 600% respectively. Also, an overall throughput improvement is recorded for the SDIoT when compared to traditional IoT network for all the nodes.

Full textAbstract:
The integration of Software Defined Networking (SDN) technologies in Passive Optical Networks (PONs) would provide great advantages to Internet Service Providers (ISPs) and Network Operators, since they can optimize the network operation and reduce its complexity. However, some tasks regarding online service and network configuration strategies are difficult to move to external SDN-controllers since they are time-critical operations. However, the control of some of these policies by SDN techniques could lead to better network and management configuration in a centralized and automatic way. As a consequence, we propose and experimentally test the integration of an OpenFlow approach over legacy Gigabit Passive Optical Networks (GPONs), which allows moving some global service configuration policies to an external SDN controller implementing an SDN management layer that adjust these strategies according to dynamic Quality of Service (QoS) requirements of services in residential users. The viability and efficiency of our approach are demonstrated using a GPON testbed and proposing a new business scenario for ISPs and Network Operators.

Full textAbstract:
Despite the huge success and adoption of computer networks in the recent decades, traditional network architecture falls short of some requirements by many applications. One particular shortcoming is the lack of convenient methods for providing quality of service (QoS) guarantee to various network applications. In this dissertation, we explore new Software-Defined Networking (SDN) mechanisms to provision QoS to targeted network flows. Our study contributes to providing QoS support to applications in three aspects. First, we explore using alternative routing paths for selected flows that have QoS requirements. Instead of using the default shortest path used by the current network routing protocols, we investigate using the SDN controller to install forwarding rules in switches that can achieve higher bandwidth. Second, we develop new mechanisms for guaranteeing the latency requirement by those applications depending on timely delivery of sensor data and control signals. The new mechanism pre-allocates higher priority queues in routers/switches and reserves these queues for control/sensor traffic. Third, we explore how to make the applications take advantage of the opportunity provided by SDN. In particular, we study new transmission mechanisms for big data transfer in the cloud computing environment. Instead of using a single TCP path to transfer data, we investigate how to let the application set up multiple TCP paths for the same application to achieve higher throughput. We evaluate these new mechanisms with experiments and compare them with existing approaches.

Full textAbstract:
Resource management is of paramount importance in network scenarios and it is a long-standing and still open issue. Unfortunately, while technology and innovation continue to evolve, our network infrastructure system has been maintained almost in the same shape for decades and this phenomenon is known as “Internet ossification”.
Software-Defined Networking (SDN) is an emerging paradigm in computer networking that allows a logically centralized software program to control the behavior of an entire network. This is done by decoupling the network control logic from the underlying physical routers and switches that forward traffic to the selected destination. One mechanism that allows the control plane to communicate with the data plane is OpenFlow. The network operators could write high-level control programs that specify the behavior of an entire network.
Moreover, the centralized control makes it possible to define more specific and complex tasks that could involve many network functionalities, e.g., security, resource management and control, into a single framework.
Nowadays, the explosive growth of real time applications that require stringent Quality of Service (QoS) guarantees, brings the network programmers to design network protocols that deliver certain performance guarantees. This thesis exploits the use of SDN in conjunction with OpenFlow to manage differentiating network services with an high QoS. Initially, we define a QoS Management and Orchestration architecture that allows us to manage the network in a modular way. Then, we provide a seamless integration between the architecture and the standard SDN paradigm following the separation between the control and data planes.
This work is a first step towards the deployment of our proposal in the University of California, Los Angeles (UCLA) campus network with differentiating services and stringent QoS requirements. We also plan to exploit our solution to manage the handoff between different network technologies, e.g., Wi-Fi and WiMAX. Indeed, the model can be run with different parameters, depending on the communication protocol and can provide optimal results to be implemented on the campus network.

Vehicle to Everything (V2X), y compris véhicule à véhicule (V2V) et véhicule à infrastructure (V2I), est la base de communications véhiculaires, où Les messages de sécurité routière active, d’infotainment et de gestion du trafic sont transmis sur des liaisons à bande passante élevée, à faible temps de latence et à haute fiabilité, ouvrant ainsi la voie à une conduite totalement autonome. L’objectif ultime des systèmes de communication V2X de la prochaine génération est de permettre une conduite coopérative sans accident. Pour atteindre cet objectif, le système de communication devra permettre un ensemble diversifié de cas d'usage, chacun avec un ensemble spécifique d'exigences. L'analyse des exigences relatives aux principales catégories de cas d’usage, en particulier les applications de temps réel critiques, souligne la nécessité d'une conception de système V2X efficace, capable de fournir les performances du réseau. La technologie de cinquième génération (5G), avec sa Qualité de Service (QoS) fournie en termes de capacité élevée et de faible temps de latence, est préconisée comme solution pour faire face aux exigences strictes imposées par les applications V2X.Dans cet écosystème 5G véhiculaire, diverses technologies de communication sont envisagés, allant des communications IEEE 802.11p, LTE, LTE-V aux Visible Light Communications. Par conséquent, l’hétérogénéité des technologies d’accès radio suscitera des inquiétudes quant à la gestion transparente de la mobilité et à la garantie de qualité de service.Cette thèse propose un nouveau système de gestion de la mobilité conçu pour les réseaux de véhicules 5G, basé sur la technologie émergente SDN (Software Defined Networking). SDN offre une programmabilité réseau qui vise à obtenir une allocation efficace des ressources du réseau et une gestion de la mobilité.Notre travail de recherche vise trois objectifs. Dans un premier temps, nous concevons une architecture de réseau de véhicules. Au sommet de cette architecture, nous implémentons deux Applications SDN, à savoir application de sélection de réseau et gestion de la mobilité Application. L'architecture proposée est renforcée par une solution de placement de contrôleur visant à réduire le temps de latence des communications. De plus, une préoccupation particulière est consacrée à la conception d’une application de sécurité active de la route SDN contrôlant l’emplacement des capteurs de vitesse sur les routes. L’application proposée vise à réduire le taux d’accidents, objectif principal du futur système de transport intelligent.Le deuxième objectif de cette thèse aborde le problème de la gestion de la mobilité.Ceci est réalisé en implémentant des applications liées à la mobilité SDN au sommet de la topologie de réseau adoptée. La première application est dédiée à la résolution du problème de sélection du réseau. Son objectif est de mapper les sessions V2X en cours sur la technologie correspondante. La deuxième application est conçue pour résoudre le handover; ceci est réalisé en utilisant la duplication de paquets et en introduisant un algorithme de routage efficace.Le troisième objectif de la thèse est axé sur l’approvisionnement en qualité de service pour les communications V2XVehicle to everything (V2X), including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure(V2I), is the umbrella for the vehicular communication system, where active road safety, infotainment and traffic management messages are transmitted over high-bandwidth, low-latency, high-reliability links, paving the way to fully autonomous driving. The ultimate objective of next generation V2X communication systems is enabling accident-free cooperative driving that uses the available roadway efficiently. To achieve this goal, the communication system will need to enable a diverse set of use cases, each with a specific set of requirements.The main use case categories requirements analysis, specifically the critical realtime applications, points out the need for an efficient V2X system design that could fulfill the network performance. The Fifth Generation (5G) technology, with its provisioned QoS features in terms of high capacity and low latency, is advocated as a prominent solution to cope with the firm requirements imposed by V2X applications.In this multifaceted vehicular 5G ecosystem, diverse communication technologies are envisioned, spanning from IEEE 802.11p, LTE, LTE-V to vehicular visible light communications. Therefore, the heterogeneity of radio access technologies will raise a concern regarding the seamless mobility management and the quality of service guarantee.This thesis provides a novel mobility management scheme devised for 5G vehicular networks based on the emerging Software Defined Networking (SDN) technology.SDN provides network programmability that strives to achieve an efficient network resource allocation and mobility management.Our research work tackles three objectives. At a first stage, we design a software defined vehicular network topology. On the top of this topology, we implement twoSDN applications, namely Network Selection Application and Mobility Management Application. The proposed architecture is enhanced by a controller placement solution that aims at reducing communication latency. Moreover, a special concern is devoted to design a SDN road active safety application that controls speed traps placement. The proposed application aims at reducing accidents rate which is a main purpose of future Intelligent Transportation System.The second objective of this thesis tackles the mobility management problem. This is achieved by implementing SDN mobility related applications on the top of the adopted network topology. The first application is dedicated to solve the network selection problem; it aims at mapping running V2X sessions to the corresponding technology. The second application is conceived to solve the handover procedure; this is achieved using packets duplication and introducing an efficient routing algorithm.The third thesis objective is focused on QoS provisioning for V2X communications

SDN centralise le plan de contrôle du réseau et gère les ressources des liens tandis que NFV virtualise les ressources des nœuds et transforme les fonctions réseau en VNFs. Dans cette thèse, nous analysons et proposons de résoudre certaines difficultés que pose la mise en place de services réseau dans cet écosystème. Nous abordons d’abord la mise en place d’un service de connectivité à qualité de service garantie. Afin d’éviter un afflux de messages vers le contrôleur et un délai dans l’application de la politique d’accès nous transférons son exécution dans le plan de données. Nous proposons ensuite de rajouter des fonctions réseau à nos services. Nous formulons un algorithme de placement visant à épargner les ressources là où elles sont rares pour placer un maximum de services. Nous doublons cet algorithme d’une technique d’abstraction de la topologie du réseau afin de permettre aux entités tierces d’exposer et vendre leurs ressources sans divulguer les détails de leurs infrastructures. Enfin, pour permette à l’opérateur réseau d’acheter les ressources nécessaires à l’établissement de ses services pour un coût minimal nous proposons un algorithme d’optimisation des réservations basé sur les offres des opérateurs de datacenters ainsi que sur des prévisions de traficNetwork traffic keep growing and newneeds are emerging today with strong requirements in terms of resources and quality of service. To face them 5G relies on control plane centralization and abstraction of resources based on SDN and NFV which allow network services deployment automation, resources utilization optimization and cost reductions. SDN centralizes the network control plane and manages link resources while NFV virtualizes node resources and turns network functions into VNFs. In this thesis we analyze some of the difficulties raised by the establishment of a network service in this context and we propose solutions to solve them. We first tackle the setup of a connectivity service with guaranteed quality of service. To avoid a massive flow of monitoring information to the controller and a delay in the enforcement of the policy we transfer the policy’s execution to the data plane. Then our goal is to add network functions to our services. We design a placement algorithm that spare resources where they are scarce to save them for services that need them to place a maximum of services. We develop a topology abstraction technique to allow other tenants to expose and sell their resources without disclosing the details of their infrastructures. Finally, to help the network operator to buy the resources required to instantiate its network services at a minimal cost we propose an algorithm that optimizes resource reservations based on cloud operators’ commercial offers and network operator’s traffic predictions

Full textAbstract:
Le concept de réseau véhiculaire qui initialement prônait essentiellement des communications de véhicules à véhicules s'ouvre à d'autres types de communications impliquant véhicules et infrastructure (réseau), cloud ou piétons, etc. afin de pouvoir répondre aux besoins de la grande variété des nouvelles applications envisagées dans le cadre du Système de Transport Intelligent (ITS: Intelligent Transportation System). La multitude des technologies réseau d'accès, la très forte mobilité des véhicules et leur forte densité en milieu urbain ainsi que la prédominance des communications sans-fil en font un réseau hétérogène, avec des caractéristiques très dynamiques, dont certaines peu prévisibles, et sujet à des problèmes d'échelle. Face à ces difficultés, une piste envisagée par la communauté scientifique est d'appliquer le paradigme SDN (Software Defined Network) aux réseaux véhiculaires comme moyen pour, d'une part permettre l'hybridation et l'unification du contrôle des différentes technologies réseaux d'accès et, d'autre part, tirer partie de la vue centralisée du réseau et des données contextuelles venues du cloud pour développer des nouveaux algorithmes de contrôle pouvant potentiellement reposer sur la prédiction/estimation de l'état du réseau et donc anticiper certaines décisions de contrôle. C'est donc dans ce cadre que s'inscrit ce travail de thèse dont les contributions visent à développer le concept de réseaux véhiculaires définis par logiciel SDVN (Software Defined Vehicular Network). Quatre contributions y sont développées. La première précise l'architecture d'un réseau véhiculaire SDN hybride capable de répondre aux défis décrits ci-avant. Cette architecture est complémentée par une solution de placement des contrôleurs SDN. Nous proposons une approche dynamique capable d'ajuster le placement optimal des contrôleurs en fonction des changements de la topologie réseau dues aux fluctuations du trafic routier. Ce travail aborde également le problème de la vision globale du réseau qu'un contrôleur SDN peut se constituer, vision préalable et pierre angulaire à toute fonction de contrôle réseau. A ce problème, nous proposons des amendements et extensions au service de découverte de topologie "de fait" conçu pour les réseaux filaires pour l'adapter au contexte véhiculaire. En complément au service de découverte, nous proposons également un service d'estimation de topologie basé sur des techniques d'apprentissage automatique (Machine Learning) pour offrir aux fonctions de contrôle réseau une vision potentielle de l'état futur du réseau et donc les ouvrir à un contrôle proactif et intelligent du réseauThe vehicular network concept, which initially focused on vehicle-to-vehicle communication, is opening up to other types of communications involving vehicles and infrastructure (network), cloud or pedestrians, etc. to meet the needs of the wide variety of new applications envisaged in the framework of the Intelligent Transportation System (ITS). The multitude of network access technologies, the very high mobility of vehicles and their high density in urban areas, and the predominance of wireless communications make it a heterogeneous network, with very dynamic characteristics, some of which are difficult to predict, and subject to scalability problems. Given these issues, one direction, considered by the scientific community, is to apply the SDN (Software Defined Network) paradigm to vehicular networks as a means of, on the one hand, enabling the hybridization and unification of control of different network access technologies and, on the other hand, taking advantage of the centralized view of the network and contextual data from the cloud to develop new control algorithms that can potentially rely on the prediction/estimation of the network state and thus anticipate certain control decisions. Therefore, this thesis is part of this framework. Its contributions aim at developing the concept of SDVN (Software Defined Vehicular Network). Four contributions are developed. The first one specifies the architecture of a hybrid SDN vehicular network capable of meeting the challenges described above. This architecture is complemented by an SDN controller placement solution. We propose a dynamic approach capable of adjusting the optimal placement of controllers according to network topology changes due to road traffic fluctuations. This work also covers the problem of global network vision that an SDN controller can build up, which is a prerequisite and the cornerstone of any network control function. To this problem, we propose amendments and extensions to the "de facto" topology discovery service designed for wired networks to adapt it to the vehicular context. As a complement to the discovery service, we also propose a topology estimation service based on Machine Learning techniques to provide network control functions with a potential vision of the future state of the network and thus open them to proactive and intelligent network control

In a smart grid machine to machine communication environment, the separation of the control and data planes in the Software Defined Networking (SDN) paradigm increases flexibility, controllability and manageability of the network. A fully integrated SDN based WSN network can play a more prominent role by providing ‘last mile' connectivity while serving various Smart Grid applications and offer improved security, guaranteed Quality of Service and flexible interworking capabilities. Hence, more efforts are required to explore the potential role of SDN in Smart Grid communications and thereby ensure its optimum utilization. In this chapter we provide a description of how SDN technology can be used in WSN with an emphasis on its end-to-end network architecture. We then present its novel application to Advanced Metering Infrastructure, Substation Automation, Distributed Energy Resources, Wide Area Measurement Systems, and Roaming of Electric Vehicles in Smart Grids.

Full textAbstract:
In applications such as video surveillance systems, cameras transmit video data streams through network in which quality of received video should be assured. Traditional IP based networks cannot guarantee the required Quality of Service (QoS) for such applications. Nowadays, Software Defined Network (SDN) is a popular technology, which assists network management using computer programs. In this paper, a new SDN-based video surveillance system infrastructure is proposed to apply desire traffic engineering for practical video surveillance applications. To keep the quality of received videos adaptively, usually Constraint Shortest Path (CSP) problem is used which is a NP-complete problem. Hence, heuristic algorithms are suitable candidate for solving such problem. This paper models streaming video data on a surveillance system as a CSP problem, and proposes an artificial bee colony (ABC) algorithm to find optimal solution to manage the network adaptively and guarantee the required QoS. The simulation results show the effectiveness of the proposed method in terms of QoS metrics.
