TCP Server Fault Tolerance Using Connection Migration to a Backup Server

TCP Server Fault Tolerance Using Connection Migration to a Backup Server
This paper describes the design, implementation, and performance evaluation of ST-TCP (Server fault-Tolerant TCP), which is an extension of TCP to tolerate TCP server failures. This is done by using an active backup server that keeps track of the state of the TCP connection and takes over the TCP connection whenever the primary fails. This migration of the TCP connection to the backup is completely transparent to the client. Because no changes are required on the client machine, any TCP client can access a ST-TCP server. The performance overhead of ST-TCP over standard TCP is minimal, and during normal operation its behavior is the same as that of a regular TCP. In addition, ST-TCP provides a fast and seamless failover whenever the primary server fails. This is veri£ed by a prototype implementation of ST-TCP in the Linux operating system, and experiments with a number of simulated applications which have different communication characteristics.
