Abstract

The invention discloses a method for accomplishing fault-tolerant transmission control protocol wherein a cluster system is used as the server for providing internet services, whose upper layer fault-tolerant applied system is consistent with the fault-tolerant TCP state backup granularity. When the TCP state backup is needed, the upper layer fault-tolerant application system performs backup for the previous read-write operation at a predetermined number, thus preventing the logic error on the application layer.íí

Description

technical field

[0001] The implementation method of the fault-tolerant transmission control protocol belongs to the technical field of high-availability transmission control protocol (TCP) in Internet servers and routers. Background technique

[0002] TCP (Transmission Control Protocol), as an important communication protocol in the TCP / IP protocol cluster, is widely used in Internet data transmission applications. It is used as a reliable data flow channel for everything from web browsing, remote login, to file transfer, and even in the router's Border Gateway Protocol BGP interaction. The TCP protocol is used as the fourth layer protocol in the TCP / IP protocol model. It uses the unreliable connectionless packet delivery service provided by the third layer IP protocol to provide reliable data flow-oriented connection data transmission services for the fifth layer. In order to achieve this reliability, TCP uses a "positive confirmation with retransmission" technology as the...
