The IESG has approved the following document: - 'Segment Routing IPv6 for Mobile User Plane' (draft-ietf-dmm-srv6-mobile-uplane-24.txt) as Informational RFC This document is the product of the Distributed Mobility Management Working Group. The IESG contact persons are Erik Kline and Éric Vyncke. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-dmm-srv6-mobile-uplane/ Technical Summary This document specifies the applicability of SRv6 (Segment Routing IPv6) to the user-plane of mobile networks. The network programming nature of SRv6 accomplishes mobile user-plane functions in a simple manner. The statelessness of SRv6 and its ability to control both service layer path and underlying transport can be beneficial to the mobile user-plane, providing flexibility, end-to-end network slicing, and SLA control for various applications. Working Group Summary The main issue during working group development was the document's intended track. There was consensus to aim for PS, save for one objection. Upon consultation with the 3GPP liaison from CT/CT4 it was decided that the document indeed had to be Informational (this was the reason for its 2nd IETF LC). Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Yes, there are product implementations already. Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? Joel Halpern's concern about the intended track was borne out, and his concern prompted important communications with 3GPP that resulted in useful, decisive feedback. Lionel Morand's time and energy as liaison were essential to getting 3GPP's input on the document. Suresh Krishnan helped coordinate relevant communications, many times. These folks, and all reviewers, are greatly appreciated. Personnel Document Shepherd: Sri Gundavelli Responsible Area Director: Erik Kline IESG Note This document had two IETF Last Calls: one as PS (per the authors' desire) and a 2nd as Informational (per feedback from 3GPP liaison communications). IANA Note The values defined by this document come from the FCFS portion of the "SRv6 Endpoint Behaviors" registry. There are placeholders entries already pointing to this draft.
