Hi, I did not have time to comment during today's LSR session so I am bringing this to the list. I am also adding IDR and 6man lists because all these three drafts are about the same use case.
There were a long email discussion on the 6man draft here: https://mailarchive.ietf.org/arch/msg/ipv6/4rw-pBcNZN7mzkArjUtVUzLcQJU/ back in March. There are basically two problems here: 1. which server to pick 2. how to stick to the same server when a UE (mobile device) moves The long discussion on the 6man list is mainly focused on #2. I don't know if we can say there was a conclusion, but some people (me included) believe that both problems are best solved at "app layer" instead of routing layer - just put a load balancer next to the 5G UPF.

The two related drafts listed the following three problems respectively: 1.3. Problem#1: ANYCAST in 5G EC Environment.............. 6 1.4. Problem #2: Unbalanced Anycast Distribution due to UE Mobility.................................................. 7 1.5. Problem 3: Application Server Relocation............. 7 1.2. Problem #1: ANYCAST in 5G EC Environment.............. 4 1.3. Problem #2: sticking to original App Server........... 5 1.4. Problem #3: Application Server Relocation............. 5 Why is problem #2 different in the two drafts? Is it true that none of the two drafts address problem #3? The idr draft talk about "soft anchoring" problem and solution - how is that different from the "sticky service"? Thanks.
