Abstract

The invention discloses a method for realizing SCTP (streaming control transmission protocol) protocol hot backup, a system and a server host. The method comprises the following steps: a first host is coupled with a client SCTP and backs up the coupled COOKIE to a second host; the second host activates the coupling when the fist host cannot work as usual; the kernel of the second host sets the timestamp of the COOKIE according to the current time, and computes the signature by use of a secret key so as to generate a TCB corresponding to the coupling , a server-side SCTP coupling finishes the recovery; the kernel of the second host generates and restarts the COOKIE_ECHO, and sends to the client. Therefore, the backup of the SCTP is realized by use of the features established by the SCTP; the main-standby switching of the SCTP is realized by use of the restarting process of the SCTP, the hot backup can be realized without frequently synchronizing and coupling the data between two hosts, and the process is simple and easy to realize.

Description

technical field

[0001] The invention relates to the application field of the SCTP protocol in telecommunication equipment, in particular to a method, a system and a server host for realizing hot backup of the SCTP protocol. Background technique

[0002] Usually, the hot backup of SCTP (Stream Control Transmission Protocol) is realized by synchronizing the TSN (transmission sequence number) between the active host and the backup host. Every time a data is sent and received, the active host and the backup host need to be synchronized. complex.

[0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention

[0004] In view of the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a method, system and server host for realizing SCTP protocol hot backup, so that hot backup can be realized without frequent synchronous coupling data between two hosts.

[0005] In order to achieve the abo...

Embodiment Construction

[0038] The present invention provides a method, system and server host for realizing SCTP protocol hot backup. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] see figure 1 and figure 2 , the present invention provides a method for realizing hot backup of SCTP protocol, especially suitable for realizing SCTP 1+1 hot backup of Linux kernel. The method includes a first host 10 and a second host 20, and the two hosts can communicate with each other. Specifically, the first host 10 is provided with a first internal IP and an external IP for client access; the second host 20 is provided with a second internal IP and the same external IP as the ...
