Saumitra, Having the flag is not enough since the responding node may not know the address of the requestor since intermediate peers may keep state and give only their address in the via list. The other issue is how does the sending peer know that it has a routable address and this is what the relay draft suggest. Roni Even

I was asking that this support be added to the base draft. I think the relay issue and the direct routing issue can be separated as they require different levels of solutions.

Thanks Roni Even -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Das, Saumitra Sent: Tuesday, February 17, 2009 8:12 AM To: [email protected] Subject: [P2PSIP] direct routing support in RELOAD Hi all, In the last meeting there was a discussion on direct routing and the conclusions were (if I recall correctly) that this should not be something that complicates the protocol and that we could have support for indicating the use of direct routing if the deployment is amenable to such a scenario. I would like to propose we add a flag bit in the forwarding/common header that indicates that a direct routing response to a message be used by the responding node. As a policy, implementations in certain scenarios would enable the flag as necessary. We can indicate that the responding node need not keep state to minimize complications. The sending node can simply resend a request (e.g STORE) with the flag turned off if does not receive a response to the initial STORE request with the flag turned on. This allows direct routing support in scenarios where the deployer or the implementation knows it is dealing with reachable IP addresses. This is also possible without any complications to the base protocol.
