What about the old stream, i.e. when do we cut out the stream from the old address. I.e. If I am at address A, and send update for address B, when do the gateway stop sending packets to my A address, and when does it start sending them to B. If I am still able to receive packets in address A, then I would like to get my packets there until they are moved to address B (i.e. no packets dropped there). If I am not able to receive packets in address A, and I am moving to address B, there will be packets dropped anyways, so I could simply inform the gateway that it can stop sending my packets to address A immediately, and continue sending them to B when the RR is finished. -- [email protected]
