ETSI has published a new IPv6 Enhanced innovation (IPE) Group Report (GR) “5G Transport over IPv6 and SRv6” (ETSI GR IPE 005). A joint effort by Post Luxembourg, China Telecom, Globe Telecom, the University of Luxembourg and Huawei, this report discusses the role of networking technologies including Internet Protocol version 6 (IPv6) and Segment Routing version 6 (SRv6) in supporting the current and future requirements of 5G networks and applications:

As 5G networks are deployed worldwide, new services appear and new requirements on the packet transport and backhaul networks arise. Current network architectures may still support the initial demand posed by 5G, yet it is fundamental to make packet networks ready to address the requirements of the coming services. Applications such as Massive Machine Type Communications (MMTC), Industrial Internet of Things (IIOT), Ultra-Reliable Low-Latency Communications (URLLC) and distributed Cloud services will push the demand well beyond the present capabilities.
