TCP Multi-Home Options

{ j, ^[, , j (sw)


In the existing TCP, only one local and one remote address is used throughout a TCP session, even when a client or a server is located under multi-homed site and has multiple IP addresses. When a network outage occurs and the access-line associated with the local and remote addresses is down, the TCP session itself gets lost even if another access-line is alive. TCP MH option makes it possible to handle multiple local and remote address pairs in one TCP session and to survive network outages by finding out an alternative network path. Our path transition mechanism is simple, fast, lightweight and as secure as the existing TCP.
