<p>A system for re-establishing a session between first and second hosts attached to respective first and second access routers. A connection request is sent from the first host to the first access router, the request containing an IP address claimed by the second host, a new care-of-address for the first host, and a session identifier. Upon receipt of the connection request, the first router obtains a verified IP address for the second access router and sends an on link presence request to the second access router, the request containing at least an Interface Identifier part of the second host's claimed IP address, the cue-of-address. and the session identifier. The second access router confirms that the second host is attached to the second access router. The second access router then reports the presence status to the first access router.</p> |
