Method and apparatus for backing up TCP connection

摘要

A method for backing up a TCP connection includes: a data transmission process and a data receiving process. The data transmission process includes: obtaining, by an AMB of a transmitting end, boundary information of data; backing up the data and the boundary information of the data to a SMB of the transmitting end; the data receiving process includes: backing up, by the SMB, data received from a peer side of the TCP connection and the boundary information of the data received by the peer side to the AMB; deleting the data received by the peer side from the data backed up by the SMB during the transmission process according to the boundary information of the data received by the peer side. The present invention also provides an apparatus for backing up a TCP connection. The method and apparatus for backing up TCP connection ensure the integrality of the data, the reliability of the switchover and improve the transmission efficiency. Furthermore, the method and apparatus for backing up TCP connection may be implemented without the dependency on the application module, therefore has a wide range of applications.
