Problems solved by technology

However, it cannot solve the problem of the failure of the host A itself. When the host A is abnormal (for example, the server will inevitably have various failures, the reasons may be equipment failures, operating system failures, software system failures, etc.), business still interrupt

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, an embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] According to one embodiment of the present invention, a kind of method based on SCTP protocol dual-system hot backup is provided, involving main machine, standby machine and opposite end, comprising the following steps:

[0038] Step 1: In the SCTP association establishment phase, establish the first SCTP connection between the host and the peer. The first SCTP connection includes two SCTP links, the main link is the link from the host IP to the peer IP, and the backup link is the link from the standby IP to the peer IP.

[0039] In this step, the upper-layer a...

Abstract

The invention provides a dual-engine hot standby method, which comprises the following steps: 1) a main engine initiates a first SCTP connection to an opposite end, and an active link and a standby link are arranged in the first SCTP connection, wherein the standby IP is set as the local standby IP of the main engine; 2 ) the main engine transmits relevant information of the first SCTP connectionto a standby engine in real time; 3 ) the standby engine establishes a second SCTP connection locally according to the relevant information of the first SCTP connection, and the active link and the standby link are arranged in the second SCTP connection, wherein the IP of the main engine is set as a local main IP of the standby engine end, and the actual IP of the standby engine is set as the local standby IP; moreover, the two SCTP connections use the same SCTP connection identifier, and the standby link in the second SCTP connection is kept alive by the standby engine through a SCTP HEARTBEAT message. The invention further provides a corresponding dual-engine hot standby system. According to the method and the system, a user service can be ensured to carry out uninterruptedly and is easyto popularize.

Description

technical field [0001] The invention relates to the technical field of high-availability computer systems, in particular, the invention relates to a dual-machine hot backup method and system. Background technique [0002] A high-availability computer system refers to a computer system that has been specifically designed to reduce downtime and maintain high availability of its services. High availability includes aspects such as protecting the integrity of business-critical data and maintaining continuous operation of applications. High availability generally represents the level of service that applications, services, and systems can provide. It can also be used to describe various enterprise goals and technical requirements, including critical goals from hardware to overall services. Among them, the least downtime is one of the key goals of high availability. [0003] Generally speaking, it may take 10 minutes, hours or even days to restore the server to normal when the t...
