Hi Linda, John,

I have the following questions.

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.
Jeffrey
