Embodiment Construction

[0021] In order to further illustrate the technical means adopted by the present invention and the achieved effects, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] see figure 1 , is a schematic flowchart of the SCTP communication method of the present invention.

[0023] SCTP communication method of the present invention, comprises the following steps:

[0024] S101 sets the IP addresses of the host computer and the backup computer in the local device to be the same, and sets the IP address of the backup computer to be invisible to the peer device;

[0025] S102 When the host in the local device communicates with the peer device, synchronize the SCTP coupling information on the host and the standby device in real time;

[0026] S103 When switching between the main machine and the standby machine occurs, switch the standby machine to the main mach...

Abstract

The invention discloses an SCTP communication method comprising that: IP addresses of a host computer and a standby computer in a home-terminal device are arranged to be identical, and the IP address of the standby computer is arranged to be invisible to an opposite-terminal device; when the host computer in the home-terminal device is communicated with the opposite-terminal device, SCTP coupling connection information on the host computer and the standby computer is synchronized in a real-time way; and when switching of the host computer and the standby computer occurs, the standby computer is switched into the host computer and the IP address of the standby computer is arranged to be visible to the opposite-terminal device, and the standby computer is communicated with the opposite-terminal device via the SCTP coupling connection information of the standby computer. Besides, the invention also discloses an SCTP communication device. IP resource is saved, coupling connection does not need to be reestablished when switching of the host and standby computers occurs, and the opposite-terminal device does not need to execute corresponding operation to match switching. A real-time synchronization mechanism is adopted by the host and standby computers so that consistency of the SCTP coupling connection information on the host and standby computers during switching is ensured, and thus speed of switching of the host and standby computers is greatly enhanced and switching time is shortened.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an SCTP communication method and an SCTP communication device. Background technique [0002] SCTP (Stream Control Transmission Protocol, Stream Control Transmission Protocol) is a transport layer protocol, which is mainly used to transmit SCN (Switched Circuit Network, circuit switching network) narrowband signaling messages through IP (Internet Protocol, Internet Protocol) network . SCTP is actually a connection-oriented transport protocol used to provide reliable connections in unreliable IP networks. Compared with TCP (Transmission Control Protocol, Transmission Control Protocol), the concept of SCTP coupling has a broader concept than TCP connection. SCTP has made some improvements to the defects of TCP, making signaling transmission more reliable. The design of SCTP includes support for proper congestion control, better real-time performance and multi-homing ...
