Jeffrey, 

Very good observation! 

The "Sticky to the original server" is the main problem addressed by the \
draft-dunbar-6man-5g-edge-compute-sticky-service. 

The draft-dunbar-idr-5g-edge-compute-app-meta-data is about propagating the \
properties and the preferences about the site to address the "Unbalanced Anycast \
Distribution due to UE Mobility" and the "App Server Relocation". 

We are working on adding more to draft-dunbar-6man-5g-edge-compute-sticky-service to \
address the "App Server Relocation" issue. Your suggestions are greatly appreciated. 

Thanks, 

Linda

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
