Radhika,

In my view there is a fundamental difference between the scheme that you are proposing and the other contributions on inter-administrative-domain communication:

Your proposal continues to expect all RAS, call setup, media negotiation and, (for all I know - it's not clear to me in your proposal), data packets associated with a call to follow a path through intermediate entities that are on the path that address resolution messages happened to take.

All the other proposals I have seen preserve a separation between the resolution phase (where messages may indeed need to be sent to a number of different places), and the call signalling stage which follows a more direct route between endpoints.

Your proposal requires the addition of extra fields to almost all RAS messages, and will generate a significant amount of extra call signalling traffic on the global network.

I still fail to understand what the technical (or business) advantages of this extra propogation of messages are. My impression was that the vast majority of the people on last Friday's conference call share my scepticism.

Regards, Chris
