I'm sorry, it is error in my last e-mail. It should be section 9.4 rather than section 9.5 which is inconsistent with section 11.

Section 9.5 doesn't actually conflict with the notion that the initial attach is routed to the JP's resource-id, though. 9.5 simply says that if peer A learns of peer B through peer C, it needs to send the ATTACH through peer C. This is simply because A may not have connectivity with B other than through peer C, such as when an overlay has been partitioned and is now healing. The initial ATTACH is essentially handled the same way, because it is routed via the BP. Bruce On Mon, Oct 25, 2010 at 6:56 PM, <[email protected]> wrote: Yes, these methods are also ok. It appear to be inconsistent between section 9.5 and section 11. I think the method in section 11 is more efficient.

So JP either can a) Send a ping to the resource id+1 (as the node_id of JP) to get the node-id (in the RELOAD message signature of the Ping answer) to then perform an attach to this node_id (this is mentioned in 9.4) or b) directly form a resource-id+1 (as JP's node_id) and send an attach. Do you agree ? Cheers, Frederic On Mon, Oct 25, 2010 at 9:04 AM, <[email protected]> wrote: I think JP is correct. The Node of JP is as Resource-ID in Attach. Before Attaching, a Ping message is redundant. There is the description above the second dirgram in the draft: "It sends an Attach to the Resource-IP AP+1, which gets routed to NP." "Resource-IP" should be "Resource-ID".

I think it should be AP ? JP has got the node-id of AP from a previous ping, right ? If that assumption is not right, the attach to node-id JP will fail, because 5.5.1 states that the attach to a node-id which isn't reached will fail.
