摘要
The fault-tolerance of TCP is a key technology to guarantee the availability of services for servers. A fault-tolerant TCP scheme based on multi-images is discussed in this paper. Each TCP connection in this scheme exists two synchronous connection images and it is no need to backup the status of every TCP connection. It issues a module mechanism in the kernel of Linux and does not affect the software running on both client and server. It also guarantees each TCP connection be taken over seamlessly when it fails, transparent to the user. At the same time, it also tries to reduce the side effect to the system performance on the premise of ensuring the fault tolerance of each connection.
