Segment routing (SR) for IPV6 (SRV6) techniques for steering user plane (UP) traffic through a set of user plane functions (UPFS) with traffic handling information

摘要

A user plane function (UPF) for use in a mobile network may receive an Internet Protocol version 6 (IPv6) data packet which includes a segment routing header and a payload containing user plane (UP) traffic data associated with a user equipment (UE). The segment routing header may indicate a list of segment identifiers comprising IPv6 addresses. Each first address portion of an IPv6 address may indicate a location of a corresponding UPF in a set of UPFs which define a forwarding path of the IPv6 data packet in the mobile network. Each second address portion of an IPv6 address may indicate one or more rules, actions, or parameters (e.g. forwarding action rules, buffering action rules, etc.) to be applied to the IPv6 data packet at the corresponding UPF in the set of UPFs indicated by the first address portion that is associated with the second address portion.
