<DIV dir=ltr><FONT face=Arial size=2>Thank you very much for the reply. However, I think tcpcp will not solve the problem because tcpcp is useful to migrate tcp connection from place to place <FONT face=Arial size=2>(correct me if I am wrong). W</FONT></FONT><FONT face=Arial size=2>hat I want to achieve is to replace the warm-up connection with an already established actual connection (so that replaced new connection both does have the same previous flow control of actual connection and doesn't go into slow start process by having congestion control state of warm-up). </FONT></DIV>

<DIV dir=ltr>I have a question on the TCP handoff. Let's assume that there is an actual TCP connection between host-1 (H1) and Host-A (HA). Meantime, host-2 and Host-A (HA) establishes a warm-up connection to be handovered. Is it ever possible to replace the actual connection with the warm-up connection let's say that because H1 moves? (is this against to the end-to-end semantics of TCP?) If so, what mechanisms could be used to achieve the handoff? (i.e. TCP stack modifications, socket layer modifications, middleware on top of TCP, etc...)</DIV>
<DIV dir=ltr>I appreciate your answers.</DIV>
