Network Operator Perspectives on NFV priorities for 5G
Today, twenty-three network operators published a white paper to guide the industry on priorities for NFV to deliver the industry vision for 5G systems: “Network Operator Perspectives on NFV priorities for 5G”. The network operator co-authors include Bell Canada, BT, CableLabs, CenturyLink, China Mobile, China Unicom, Colt, Deutsche Telekom, KDDI, KT, NTT, NTT DOCOMO, Orange, Portugal Telecom, Rogers, SK Telecom, Sprint, STC, Swisscom, Telecom Italia, Telefonica, Telenor, and Vodafone. As managing editor for this white paper, I worked closely with colleagues from these leading organisations to document some key consensus requirements that we want the 5G standards community to take into account in their upcoming specification work.
We believe the evolved 5G network will be characterised by agile resilient converged fixed/mobile networks based on NFV and SDN technologies and capable of supporting network functions and applications encompassing many different networks and services domains. The breadth of foreseen 5G use cases and environments implies high scalability, ultra-low latency and ability to support a massive number of concurrent sessions, as well as ultra-high reliability and security. To achieve these ambitious goals, Network Slicing, Cloud-native design principles, End-to-end Service Management, Edge Computing, RAN Cloudification, Multi-site/domain Services, NFV License Management, Security, Reliability, and Scalability are important enablers as outlined in some detail in this paper.
In an era of increasingly stretched resources, it is vitally important for standards development organisations and open source communities to avoid re-invention and wasteful duplication of effort. Hence, an important message is to encourage reference to the extensive body of foundational NFV specification work already published by the ETSI NFV Industry Specification Group over the past four years as the basis for 5G.
As managing editor, I believe this white paper should be used as guidance for the wider industry on how NFV should be used to realise 5G use cases.
