Hi, This version follows a careful review by Toerless. There are three significant changes:
1. There is some explanation, mainly in an Appendix, about how this solution can co-exist with existing mechanisms for prefix delegation, especially DHCPv6/PD. In a few words, we'd use the autonomic solution to provide prefixes to edge devices, and conventional methods to delegate prefixes at the edge. Thus the client routers don't need to be in the trusted autonomic domain. 2. There is not complete agreement among the authors, but for now we have removed the "PD" flag from the GRASP objective, because the use case for it was very unclear (why bother to negotiate with GRASP and then add an extra step with DHCPv6?). 3. We have included two possible ways to add IPv4 prefix management. Comments are needed. Especially, should we include one of the IPv4 mechanisms in the final version? For people who like running code, there's a demo version at https://www.cs.auckland.ac.nz/~brian/graspy/pfxm3.py A screen shot of four instances working together is at https://www.cs.auckland.ac.nz/~brian/graspy/prefixen.png Regards Brian + co-authors On 23/06/2017 15:31, [email protected] wrote: > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > This draft is a work item of the Autonomic Networking Integrated Model and > Approach of the IETF. > > Title : Autonomic IPv6 Edge Prefix Management in > Large-scale Networks > Authors : Sheng Jiang > Zongpeng Du > Brian Carpenter > Qiong Sun > Filename : draft-ietf-anima-prefix-management-04.txt > Pages : 21 > Date : 2017-06-22 > > Abstract: > This document describes an autonomic solution for IPv6 prefix > management at the edge of large-scale ISP networks, with an extension > to support IPv4 prefixes.
