“…The joint optimization of the SFC is carried out by ensuring indicators such as end-to-end QoS are satisfied. However, the reliability is measured by t nor /t en (1) where t nor represents the uptime of VNF, and t en represents the entire working time of VNF. This metric is not a convincing or fundamental generalization.…”

“…NFV makes use of virtualization technologies to divide the functions of each network node into separated blocks. These functional blocks are carried out in software, and are no longer confined to the hardware structure [1]. As shown in the NFV network operation architecture of Fig In a virtualized network, the user requests may need to go through different network functions.…”

With the advancements of Software Defined Networking and Network Function Virtualization technologies, users can access the software-based service function chain (SFC), which is composed of multiple sequential virtual network function (VNF) nodes. Although SFC is more flexible and adaptive in terms of design and deployment, the security risks should not be underestimated. At present, there is a lack of security or risk assessment for SFC, and SFC deployments rarely take their security into account. However, vulnerabilities and risks can cause VNF node failure during operation, which can lead to issues such as disruptions in SFC service and user data leakage. This paper proposes the concept of SFC credibility, which quantifies the authenticity, availability, and reliability of the VNF nodes from both time and space dimensions. Then, a hierarchical credibility evaluation model is built such that VNF nodes can be selected for the user based on their trustworthiness. A credibility-based deployment strategy is further designed for SFC and the corresponding VNF forwarding graph. Furthermore, a comparative study with three existing deployment strategies has shown the advantages of the proposed method. The extensive experimental results demonstrate the improved trust degree and the acceptance rate of SFC with a limited budget.

This Emacs based software 7 harnesses the power of special purpose troubleshooting tools by offering an integrated platform to automate certain parts of the troubleshooting process. EPOXIDE is controlled by a troubleshooting graph (TSG)-a formal description of troubleshooting processes-where graph nodes are wrappers for troubleshooting tools or processing functions and edges direct the data flow among these.…”

This experience paper describes the process of leveraging the NFV orchestration platform built in the EU FP7 project UNIFY to deploy a dynamic network service exemplified by an elastic router. Elasticity is realized by scaling dataplane resources as a function of traffic load. To achieve this, the service includes a custom scaling logic and monitoring capabilities. An automated monitoring framework not only triggers elastic scaling, but also a troubleshooting process which detects and analyzes anomalies, pro-actively aiding both dev and ops personnel. Such a DevOpsinspired approach enables a shorter update cycle to the running service. We highlight multiple learnings yielded throughout the prototype realization, focussing on the functional areas of service decomposition and scaling; programmable monitoring; and automated troubleshooting. Such practical insights will contribute to solving challenges such as agile deployment and efficient resource usage in future NFV platforms. S.

“…On the other hand, the QoS and resource requirements of services vary greatly in different scenarios [Chernyshev, Baig, Bello et al (2017)]. Some of them even have extremely high priority and need to be done without considering QoS and resource requirements [Yousaf, Bredel, Schaller et al (2017); Rossem, Tavernier, Sonkoly et al (2015); Rossem, Peuster, Conceicao et al (2017); David and Lin (2018)].…”

With the popularization of terminal devices and services in Internet of things (IoT), it will be a challenge to design a network resource allocation method meeting various QoS requirements and effectively using substrate resources. In this paper, a dynamic network slicing mechanism including virtual network (VN) mapping and VN reconfiguration is proposed to provide network slices for services. Firstly, a service priority model is defined to create queue for resource allocation. Then a slice including Virtual Network Function (VNF) placement and routing with optimal cost is generated by VN mapping. Next, considering temporal variations of service resource requirements, the size of network slice is adjusted dynamically to guarantee resource utilization in VN reconfiguration. Additionally, load balancing factors are designed to make traffic balanced. Simulation results show that dynamic slicing mechanism not only saves 22% and 31% cost than static slicing mechanism with extending shortest path (SS_ESP) and dynamic slicing mechanism with embedding single path (DS_ESP), but also maintains high service acceptance rate.
