Problems solved by technology

[0010] The purpose of the present invention is to overcome the shortcomings of the existing dual-machine backup function, solve the problem that the existing backup protocol can only realize the dual-machine backup of the network layer, and propose an extension based on the dual-machine backup protocol to realize the application characteristics The method of dual-machine backup, which is simple, unified and efficient, enables high reliability based on the application characteristics of the network layer, thereby improving the high reliability of the entire network

Embodiment Construction

[0034] The embodiment of the method for realizing dual-device backup of application characteristics proposed by the present invention is based on extending the VRRP dual-device backup protocol to support dual-device backup of application characteristics. As shown in Figure 2, it specifically includes the following steps:

[0035] 1) The application features that require the dual-machine backup function on each device register with the VRRP running on the device, so that VRRP knows which application features on the device need the dual-machine backup function (for unregistered application features, VRRP will not support them) backup function);

[0036] 2) VRRP on each device, according to its priority, determines whether the device is the main device or the backup device (the device with the highest priority is the main device);

[0037] 3) If it is the primary device, the VRRP of the device will notify the registered application features on this device to start backing up key...

Abstract

The method is as the follows: each equipment requiring application characteristic (AC) of double machine backup function is first to be registered on double machine backup protocol of principal equipment (PE) running to confirm PE to be main-use equipment (MUE) or spare equipment (SE); on MUE, registered key data is backed up and sent to SE, on SE, backup key data is received; once SE double machine backup, protocol discovers that MUE is fault, PE is switched to be MUE and to inform received backup data to execute normal function, necessary key data is backed up and sent to new SE.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and particularly relates to helping other application characteristics to realize high reliability of dual-machine backup through binding with a dual-machine backup protocol. Background technique [0002] In an IP network, there is often a problem that the entire network connection is disconnected due to a failure of a single network device. Usually, the countermeasure is that multiple network devices back up each other. When one of the devices fails, the remaining devices will automatically replace the faulty device and continue to work, thereby improving the overall reliability of the network device. This method is called dual-machine backup. . [0003] VRRP (Virtual Router Redundency Protocol) is a dual-device backup protocol, and RFC 2338 describes the protocol specification. Two or more network devices form a backup group by running VRRP. From the outside world, this backup group ...
