Zusammenfassung:We present an implementation of a fault-tolerant TCP (FT-TCP) that allows a faulty server to keep its TCP connections open until it either recovers or it is failed over to a backup. The failure and recovery of the server process are completely transparent to client processes connected with it via TCP. FT-TCP does not affect the software running on a client, does not require to change the server's TCP implementation, and does not use a proxy.
