SRv6 for Mobile User-Plane
draft-matsushima-spring-dmm-srv6-mobile-uplane-01
Abstract
This document discusses the applicability of SRv6 (Segment Routing
IPv6) to user-plane of mobile networks that SRv6 source routing
capability with its programmability can fulfill the user-plane
functions, such as access and anchor functions. It takes advantage
of underlying layer awareness and flexibility to deploy user-plane
functions that enables optimizing data-path for applications.
Network slicing and an interworking way between SRv6 and existing
mobile user-plane are also discussed in this document.

1. Introduction
In mobile networks, mobility management systems provide connectivity
while mobile nodes move around. While the control-plane of the
system signals movements of a mobile node, user-plane establishes
tunnel between the mobile node and anchor node over IP based backhaul
and core networks.
This document discusses the applicability of SRv6 (Segment Routing
IPv6) to those mobile networks. SRv6 provides source routing to
networks where operators can explicitly indicate route for the
packets from and to the mobile node. SRv6 endpoint nodes act as
roles of anchor of mobile user-plane.
