Повний текст джерелаTack vare den senaste tekniska utvecklingen inom beräkningar i molnet(“cloud computing”) används allt fler tillämpningar i molnlösningar. Flera avdessa moderna molnbaserade tillämpningar kräver korta svarstider är låga ochatt dessa ska vara förutsägbara och ligga inom givna gränser. Den nuvarandemolninfrastrukturen är dock otillräcklig eftersom den inte kan uppfylla dessa krav,på grund av olika typer av begränsningar i både hårdvara och mjukvara. I denna licentiatavhandling beskrivs försök att minska fördröjningen iinternettjänster genom att noggrant studera den nuvarande tillgängligainfrastrukturen, optimera den och förbättra dess prestanda. Fokus ligger påatt optimera prestanda för nätverksfunktioner som realiseras med hjälp avstandardhårdvara, känt som nätverksfunktionsvirtualisering (NFV). Prestanda hosNFV är en av de viktigaste källorna till fördröjning i internettjänster. Det första bidraget är relaterat till att optimera mjukvaran. Detta projektbörjade med att undersöka möjligheten att “superoptimera” virtualiseradenätverksfunktioner (VNF). Detta inleddes med en litteraturöversikt av tillgängligasuperoptimeringstekniker, och sedan valdes ett av de toppmodernasuperoptimeringsverktygen för att analysera de viktiga mätvärden som påverkartillämpningssprestanda. Resultatet av vår analys visade att bättre cache-mätningar potentiellt skulle kunna förbättra prestanda för alla tillämpningar. Det andra bidraget i denna avhandling utnyttjar resultaten från den förstadelen genom att ta ett steg mot att optimera cache-prestanda för tidskritiskakedjor av NFV-tjänster. Genom att göra så reducerade vi de långa fördröjningarnahos sådana system som kördes vid 100 Gbps. Detta är en viktig bedrift eftersomdetta ökar sannolikheten för att uppnå en begränsad och förutsägbar fördrörninghos internettjänster.

Visser, Riaan. "Operational-cost optimisation and cost management in the sourcing and supply chain : a conceptual framework for a medium-sized service company without a central procurement function." Thesis, Stellenbosch : Stellenbosch University, 2008. http://hdl.handle.net/10019.1/997.
Повний текст джерелаENGLISH ABSTRACT: A typical medium-sized service company in South Africa faces definite challenges and misses opportunities in optimising and managing its operational expenses in its sourcing and supply chain. Medium-sized companies generally do not have the benefit of sophisticated in-house procurement divisions and extensive buying power but they still have to optimise their expenses in order to ensure maximum profitability and business longevity. The study addresses these challenges and opportunities by developing and proposing a framework for a typical medium-sized service company that does not have a central procurement function related to the cost optimisation and management of the identified sourcing and supply-chain elements. The research process entails the development of a conceptual framework developed from literature analysis and a representational practical environment as well as the testing, reviewing and validating of the test implementation of the framework. The results flowing from the testing and implementation of the framework are excluded from the research project. The results are displayed in the form of a summary of specific relevant information around each framework element as well as a conceptual framework. Recommendations are made in relation to the implementation and practical adaptation of the framework. It is concluded that a medium-sized service company can successfully optimise and manage its costs in the sourcing and supply-chain elements in the absence of a central procurement function. This requires the effective implementation of the developed framework, which was adapted from sophisticated larger companies. Implementation and the measurement process need to be driven or, preferably, conducted by the medium-sized company owner or management. Buy-in of the framework and the processes around it needs to be obtained from employees, suppliers and other stakeholders.
AFRIKAANSE OPSOMMING: ’n Tipiese mediumgrootte diensverskaffingsonderneming in Suid-Afrika staar spesifieke uitdagings in die gesig en ontbeer geleenthede met betrekking tot die optimalisering en bestuur van die bedryfsuitgawes in sy aankoop- en verskaffingsketting. Mediumgrootte ondernemings beskik in die algemeen nie oor die voordeel van ’n gesofistikeerde interne aankoopafdeling en groot aankoopkrag nie, maar hierdie ondernemings moet nog steeds hulle koste-uitgawes optimaliseer in die nastreef van maksimale wins en besigheidsukses. Die navorsingstudie neem hierdie uitdagings en geleenthede onder die loep deur die ontwikkeling en aanbeveling van ’n raamwerk vir ’n tipiese mediumgrootte diensverskaffingsonderneming wat nie oor ’n sentrale interne aankoopafdeling beskik nie. Die raamwerk is gebaseer op koste-optimalisering en -bestuur van die geïdentifiseerde aankoop- en verskaffingskettingelemente. Die navorsingsproses behels die ontwikkeling van ’n konseptuele raamwerk deur literatuuranalise en ’n verteenwoordigende praktiese omgewing, sowel as die toetsing, hersiening en geldigverklaring van die raamwerk tydens die toets-implementering daarvan in die praktiese omgewing. Die resultate van die toets en implementering van die raamwerk vorm nie deel van hierdie studie nie. Die navorsingsresultate word ten toon gestel in die vorm van ’n opsomming van die relevante raamwerkelemente sowel as ’n ontwikkelde raamwerk. Aanbevelings ten opsigte van die implementering en praktiese aanpassing van die raamwerk word dan gemaak. Die gevolgtrekking word gemaak dat ’n mediumgrootte diensverskaffingsonderneming wel in die afwesigheid van ’n sentrale interne aankoopafdeling sy kostes in die aankoop- en verskaffingsketting suksesvol kan optimaliseer en bestuur. Dit kan gedoen word deur die doeltreffende implementering en aanwending van die ontwikkelde raamwerk wat vanaf groter ondernemings aangepas is. Die raamwerk se implementering- en metingsproses moet deur die eienaar of bestuur van die mediumgrootte onderneming gelei, of verkieslik uitgevoer, word. Die werknemers, verskaffers en ander belanghebbendes se ondersteuning vir die raamwerk en gepaardgaande prosesse is baie belangrik vir die implementering en sukses van die raamwerk.

Current Network Function Virtualization (NFV) with Virtualized Network Functions (VNFs) running as virtual machines on commodity servers enables flexibility to Service Function Chaining (SFC). Specific applications may require Quality of Service (QoS) on end-to-end latency. However, the processing delay and the queuing delay of VNFs varies with virtual resource configurations (vCPU and vMemory), as well as physical usage (traffic amount, CPU utilization). Moreover, packet delays are randomly distributed, instead of a fixed value. To accurately model the latency distribution of one VNF, a prediction method using random-forest regression is proposed. Evaluation results show that our method can precisely predict the latency distribution of the two sample VNFs with only 10% errors. On the basis of the model, a QoS-assured SFC deployment algorithm is also presented to guarantee end-to-end latency and bandwidth consumption of users. Experiments show that our algorithm enables high degree of scalability, and meanwhile maximizes user acceptance rates with 6% difference from the optimal solution from the mixed integer programming.

Software-defined network(SDN) is shifting data communication in network toward more centralized control. The controller manages all necessary information and decides the transit path through commands. Middleboxes such as firewalls, decryptors, load balancers, etc., are functional hardware devices that are indispensable in the cloud and in corporate networks, but are expensive and difficult to maintain. The availability of virtual machines enables dynamic placement of virtual network functions(VNFs) on demand, it can reduce a large number of manual configuration processes, introduce flexibility, and increase deployment efficiency. Service requirements may need more than one VNF. Instead, it may need to traverse a set of sequential functional services called Service Function Chain (SFC). For example: first through the firewall, then through the encryption device, and finally through the decryption device, if these functional services are unordered, it will affect the correctness of the entire service requirements. A key challenge is to efficiently route service function chains and place processing functions in a network under operational constraints. We must overcome two challenges: (1) determining a flow path that traverses suitable processing nodes in the correct order to meet the requirements of a given service chain, and (2) considering network load and other dynamic characteristics when routing through existing VNFs. We present a method to solve the node-constrained service chain routing problem in a software-defined network. The main idea is to transform the network representation to a layered graph that considers processing steps and allows the use of conventional shortest path algorithms, such as Dijkstra’s algorithm, to solve the problem. We are not only pursuing the high efficiency of acceptance ratio, but also taking into account the execution time of the algorithm.

In recent years, as growth of the cloud computing technology, more demand for network resources allocation and management of value-added services are appeared. The new concept of network service architecture, Service Function Chain (SFC), has been proposed. The specification of various vendor equipments is unique, prompts the traditional network to change. The purpose of Software-Defined Network (SDN) is to change the physical, complex network into a virtual, programmable and open network architecture. OpenFlow protocol is the most common technology for SDN architecture. The Network management can be more flexible by the centralized and programable property of OpenFlow. VLAN and OpenFlow based Service Function Chain (VOFSFC) and services deployment mechanism are proposed to improve the flexibility of the network service deployment and reduce the consumption of network resources. VOFSFC use the virtual LAN (VLAN) technology to develop VLAN of Path adoption mechanism. It can identify different requirements of network traffic, steer/deliver packets to service functions and record information of the traffic. In addition, consider the placement of service functions, develop and propose GARCH and K-Means Service Function Placement (GKMSFP) mechanism to cluster and deploy service functions for reduce the load of network resources. The results shows the proposed VOPSFC system can provide high elasticity and flexibility for the network management, and the proposed GKMSFP mechanism can reduce 45.6% network resource consumption from the general situation which without cluster mechanism. It shows that mechanisms can reduce the traffic load of network in the SFC system.

Network function virtualization (NFV) is a new architecture that implements network functions in a virtialized environment. However, the platform for deploying network functions may be insecure. To eliminate the threat, network functions can be deployed with a trusted execution environment (TEE) mechanism such as Intel Software Guard Extension (SGX) in a secure region called enclave. In existing studies, all the network functions in a service chain are deployed in one enclave, but the enclave size is limited (up to 128MB in our investigation). In addition, the network functions need to be re-implemented from scratch to meet the requirements. In this work, we propose an approach, a service function chain with SGX-based containers, and study the performance issues on it. We deploy the network functions in several situations: on the same host, in the same container or on different hosts. We estimate the performance of packet transmission between the network functions in the same container with the shared memory mechanism (emulated by RAMdisk). In the other situations, the packets are transmitted via a switch and/or the virtual network interface controller (NIC). We also build two open-source network functions in SGX-based containers with few modifications for demonstration. In the experiments, we evaluate our system and find the throughput in shared memory can be as high as 400MB/s in packet transmission. We also find the encryption operation (AES in our experiments) and the receiving buffer size also have an impact on the throughput.

Network function virtualization (NFV) has changed the traditional usage of network functions from hardware appliances to software implementation. Placement of virtual network functions (VNFs) has become a fundamental problem in NFV. In this study, relation in VNFs, including dependency and changes of flow size, would be important factors in placement of VNFs onto virtual machines on servers. Metric embedding is adopted to combine the relation of VNFs and virtual machines on network servers. The structures shown in service chains are seized by embedding algorithm and thus reflect the result on placement of VNFs on the network. In the simulation section, the proposed technique is evaluated and performs well in test cases, showing that the proposed technique gives a fine solution to VNF placement problem.

In recent years, mobile communication technology continues to explode the progress of the relative, the network management costs are growing, because the network needs to configure a lot of settings, such as: Route, VLAN (Virtual Local Area Network), QoS (Quality Of Service), STP (Spanning Tree Protocol) and LACP (Link Aggregation Control Protocol), etc., in a large network, because the traditional network of each node settings are rigid configuration, there is no way to achieve the global vision , Resulting in network administrators from time to time need to change these configurations, for example, whenever the New Year, the crowd brought huge amounts of information poured into, causing some switches overload and collapse. SDN (Software-defined networking) is a new concept of network architecture, the main purpose is to network Flexibility, Manageability, Scalability, SDN is the biggest feature of the traditional network is divided into the control layer (Control Plane) and the data layer (Data Plane), the data forwarding decision by a single or multiple Controller to deal with, as long as the control layer and the data layer through the same open protocol OpenFlow communication, it is no longer rigidly adhere to the hardware label or model, the administrator or programmer can write software to easily achieve load balancing, so the appearance of the SDN improved Traditional networks can only be partially optimized and can not be fully configured shortcomings. Considering the network packet of the various forwarding are bundled behind a number of network services, so we think that the use of SDN project Service Function Chain architecture so that the data can be flexible to do the forwarding action, select Service Function Chain is different from the use of flow table , the flow can also be real-time conversion when the traffic generated , even when the user made a different request, but also Automatically redirect packets to the desired service, in order to achieve the balance of traffic mechanism, the use of Network Service Header attached to the data, so that the data can be indicated by the Network Service Header to go through the node, the experimental structure of this study based on an physical machine simulation of eight virtual machines, through the design of the greedy algorithm based on the service function chain to add and modify the direction and order of the various services forward, after the experimental results, the use of this method can effectively relieve traffic in high-density environment caused by congestion problems.

Due to swift Internet technology and computer hardware development in recent years, the demands of network functions are rising. Compared to hardware-based network services, it is faster and more flexible to virtualize the network services and a flows may be processed by multiple network services as a Service Function Chain (SFC). Using Software Defined Network (SDN) is highly popular in the world because it can reduce deployment cost and time. However, the performance of Network Function Virtualiza- tion will be troubled by some congenital drawbacks. For instance, Network Function Virtualization usually suffers from I/O latency because it causes lots of interrupts that decreases CPU utilization. Although this can be solved somehow such as using SR-I/OV network card to reduce the system interrupts, the methods are still not perfect because it is not compatible with existing Software Defined Network system. For example, we often runs OpenvSwitch, an OpenFlow virtual switch supporting Software Defined Network, in general purpose server’s host OS to manage all the network packets forwarded to Virtualized Network Functions (VNFs). However, with OpenvSwitch, network packets must bypass host OS to guest OS when we use SR-I/OV network card. We will lose the benefit of SR-I/OV to enable SDN by using OpenvSwitch. Therefore, we propose an integrated architecture from a wider perspective in system design to overcome main defects described above. We modify appropriate components in SR-I/OV driver and OpenvSwitch to make Service Function Chain constructed by Virtualized Network Functions perform better and compatible with Software Defined Network environment.

The purpose of this study is to understand the consumers’ acceptance over self-order service and the key function needs. Hopefully the result of this study would furnish the chain fast food restaurants with a good reference regarding to offering self-service. Based on Technology Acceptance Model (TAM), Direct Benefit and Deferred Benefit are adopted as external variables for Perceived Usefulness and User Interface and Information Content are adopted as external variables for Perceived Ease of Use. Totally 130 responses were collected via an internet based questionnaire. Among these responses, 109 responses are valid. Regression and Partial Least Squares (PLS) were used to analyze the responses collected. According to the responses, Deferred Benefit is positively related to Direct Benefit and Direct Benefit is positively related to Perceived Usefulness. Information Content is positively related to User Interface and User Interface is positively related to Perceived Ease of Use. Comparing the results with TAM, this study found that Intention to Use is more significantly positively related to Perceived Ease of Use than to Perceived Usefulness. This study also found that Direct Benefit, such as discount, and User Interface, such as provide content for the latest order, are very important for consumers. The results provide the chain fast food restaurants a useful reference for providing self-service.
