Abstract

The invention provides an information backup method. The method is applied to a TCP (transmission control protocol) proxy equipment group. The TCP proxy equipment group comprises main equipment and standby equipment. The method comprises steps as follows: after the TCP proxy equipment group is started, proxy information stored by the main equipment saved during TCP proxy service execution by the main equipment is synchronized to the standby equipment; during operation of the TCP proxy equipment group, data messages received by the main equipment are synchronized to the standby equipment in real time; the standby equipment decapsulates the data messages to acquire proxy information contained in the data messages. With the application of the embodiment, the data messages received by the main equipment are synchronized to the standby equipment, and time consumption caused when the main equipment decapsulates the proxy information from the data message before backup is avoided. When the main equipment goes down, access interruption can be avoided for users who are using proxy services because the proxy information in the main equipment is identical with that in the standby equipment, and better user experience is obtained.

Description

technical field

[0001] The present application relates to the technical field of communications, and in particular to a method and device for backing up information. Background technique

[0002] A TCP (Transmission Control Protocol, Transmission Control Protocol) proxy device is generally deployed on a critical path of the network, and the stability and security of the device directly affect the availability of the network. In order to avoid a single point of failure, two TCP proxy devices are generally deployed on the same path, one as the main device to process business normally, and one as the backup device to keep the standby state, and the main device will back up the proxy information in real time when processing the proxy business to the backup device. When the main device fails, the business traffic can be switched from the main device to the backup device to ensure the smoothness of the network.

[0003] In the prior art, for the information backup of two TCP pro...
