Hi Fred,

Thanks for the comment. I have read draft-ietf-rtgwg-atn-bgp also. I
think that the hub and spoke architecture will end up being similar,
but I'm not sure that this is exactly the same thing. One difference
is that draft-ietf-rtgwg-atn-bgp is targeted to particular
application, whereas draft-herbert-intarea-ams endeavours to be
general purposes. There are differences especially in scalability. For
instance, rtgwg-atn-bgp mentions network with millions of routes, and
in draft-herbert-intarea-ams the target is to support networks with
billions of active addresses for IoT networks. And if we do get to
unique address per flow, then the total number of addresses to be
managed is much more (hence why hidden aggregation becomes
interesting).

Another consideration is MEC servers providing services to UEs at they
edge. If they participate in the routing/mapping system (as an ASBR-s
in draft-ietf-rtgwg-atn-bgp and AMS-F in AMS) then the end device can
perform overlay routing itself. That is very efficient for lowest
latency. There may be many MEC servers and each one might only be
communicating with a small subset of all possible nodes. This seems to
motivate a working set cache to that limits the number of mappings as
well as the amount of control plane communications.
