This is a use case: The user plane of 5G is distributed, and MEC is deployed as part of the user plane to provide some functions at Access Aggregation Ring or Regional Aggregation Ring or at the border between Regional Aggregation Ring and the National Core. Using TTZ, MEC or part of it can be virtualized and topologically simplified. Note that the outside really doesn’t care about the internals of MEC.
Thanks, Richard From: Lsr <[email protected]> On Behalf Of Robert Raszuk Sent: Tuesday, August 18, 2020 2:25 PM To: Acee Lindem (acee) <[email protected]> Cc: [email protected] Subject: Re: [Lsr] LSR WG Adoption Poll for "IS-IS Topology-Transparent Zone" - draft-chen-isis-ttz-11.txt Dear WG, The draft in question does not describe even a single practical use case. While it describes the mechanics on how to construct the new model of the abstraction it fails to prove we need it. Not everything which can be invented should be standardized or implemented therefore until the document extensively describes the real use cases with justification why use of areas may not be sufficient for such use cases I don't think LSR WG should adopt it. Regards, Robert.

These differences include abstraction at arbitrary boundaries and IS-IS extensions for smooth transition to/from zone abstraction. We are now starting an LSR WG adoption call for draft-chen-isis-ttz-11.txt. Please indicate your support or objection to adoption prior to Tuesday, September 2nd, 2020.
