Thanks Minh-Ngoc,

Leveraging a DSD(Direct Segment Discovery) advertisement to find computing resources identified with CATS IDs sounds interesting. 

Let me see more detail considerations described in your draft. My first point for that would be:

- NLRI in a DSD route corresponds which ID, CS-ID, or CIS-ID, while MUP ext-comm identifies,
- Direct segment ID in a MUP ext-comm identifies which ID, CS-ID, or CIS-ID.

IMO so far was that DSD route NLRI for CIS-ID, MUP ext-comm for CS-ID. Let me think more on that, and get back to you.

Cheers,

Abstract:

   The document [I-D.draft-mhkk-dmm-srv6mup-architecture] describes the
   Mobile User Plane (MUP) architecture for Distributed Mobility
   Management.  The proposed architecture converts the user mobility
   session information from the control plane entity to an IPv6
   dataplane routing information.  When there are multiple candidate
   instances located at different location to serve an user request, the
   MUP Provider Edge (PE) might prioritize the closest service location.
   However, the closest routing path might not be the optimal route.

   This document discusses how the mentioned MUP architecture can be
   leveraged to set up dataplane routing paths to the optimal service
   instance location with the assistance of computing-aware traffic
   steering capabilities.  For each session request, based on the up-to-
   date collected computing and network information, the MUP controller
   can convert the session information to the optimal route.
