Abstract

5G networks are already being implemented around the globe. One of the most important enablers of their penetration are the Software Defined Networking (SDN) technologies and the Network Functions Virtualization (NFV) architecture, which allow the needed flexibility of the network and the composing elements. In such circumstances, the Internet-of-Things (IoT), which has been long awaited, is becoming feasible and economically reasonable. This setup has its challenges, especially due to the network expansion toward the edge, where the number of networking elements and service consumers is rapidly rising. The compute resources and the storage have to be brought in the network proximity of the access network, so that the latency of the service is kept under 1ms, which is one of the base 5G requirements. For our research, we have made an experimental setup of a distributed NFV architecture on a multiple geo-location, with a main objective to review the network latency caused by the architectural distribution of the services that are built in it. The results can be used by researchers and network architects to build reliable and costeffective distributed services with the lowest possible latency, as well as to plan possible disaster recovery scenarios when some physical location is unavailable.

NFV资源分配对子网间时延的影响

5G网络已经在全球范围内实施。软件定义网络(SDN)技术和网络功能虚拟化(NFV)体系结构是它们渗透的最重要的推动因素之一，它们允许网络和组成元素所需的灵活性。在这种情况下，人们期待已久的物联网(IoT)变得可行且经济合理。这种设置有其挑战，特别是由于网络向边缘扩展，其中网络元素和服务消费者的数量正在迅速增加。计算资源和存储必须被引入接入网的网络附近，从而使服务的延迟保持在1ms以下，这是5G的基本要求之一。在我们的研究中，我们在多个地理位置上建立了一个分布式NFV架构的实验设置，其主要目的是检查由其中构建的服务的架构分布引起的网络延迟。研究人员和网络架构师可以使用这些结果以尽可能低的延迟构建可靠且经济有效的分布式服务，并在某些物理位置不可用时规划可能的灾难恢复场景。

期刊介绍： The TELFOR Journal is an open access international scientific journal publishing improved and extended versions of the selected best papers initially reported at the annual TELFOR Conference (www.telfor.rs), papers invited by the Editorial Board, and papers submitted by authors themselves for publishing. All papers are subject to reviewing. The TELFOR Journal is published in the English language, with both electronic and printed versions. Being an IEEE co-supported publication, it will follow all the IEEE rules and procedures. The TELFOR Journal covers all the essential branches of modern telecommunications and information technology: Telecommunications Policy and Services, Telecommunications Networks, Radio Communications, Communications Systems, Signal Processing, Optical Communications, Applied Electromagnetics, Applied Electronics, Multimedia, Software Tools and Applications, as well as other fields related to ICT. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies towards the information and knowledge society. The Journal provides a medium for exchanging research results and technological achievements accomplished by the scientific community from academia and industry.
