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.
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.
