Multi-AS needs : draft-zhang-mpls-interas-te-req-02.txt

[Jim Boyle <jboyle@pdnets.com>]

It seems to me that there are a few different requirements in this draft, 
taking a look at the scenarios in section 4, we have

1) Virtual POP - extend network through another's, place your
	edge router (PE) in someone elses POP w/o direct connectivity
	to your network.

2) Similar to 4.1, but in this case virtually extend your edge port
	onto another providers router (or all the way to customer).

3) CE to CE w/ QOS quarantees from multiple providers

4) Multi-AS TE within one Provider (e.g. global)

5) Extend one's network through another

Scenarios 1-3 and 5 to me just seem to be inter-provider VPN requirements 
(w/ a little QoS for flavor).  So it seems the bulk of the discussion 
should happen elsewhere, right?

Scenario 4 looks right up our alley though.  So I have to ask - what about 
current protocol specifications limits you from trying a few different 
approaches to Multi-AS TE?

thanks,

Jim
