Problems solved by technology

[0002] In the prior art, the session information corresponding to a cluster device that needs to be backed up is usually backed up in one or several devices corresponding to the cluster. For example, one or more central Control devices to achieve session backup, thus increasing the complexity of the entire cluster operation; at the same time, because the backup device itself is a full backup, there will also be storage data redundancy problems; and if multiple full backup devices are set , there will be dedicated line overhead between each device; further, when the cluster expands, the above-mentioned various drawbacks will become more prominent

Embodiment Construction

[0041] The application will be described in further detail below in conjunction with the accompanying drawings.

[0042] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0043] Memory may include non-permanent storage in computer-readable media, in the form of random access memory (RAM) and / or nonvolatile memory, such as read-only memory (ROM) or flash memory (flashRAM). Memory is an example of computer readable media.

[0044] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), sta...

Abstract

An aim of the application is to provide a method and device for creating a session backup at a user device end, a first access request of a user device for an object application is sent to a first network device; first access response information, comprising the application session information to be backuped, returned based on the first access request by the first network device is received; the application session information is extracted from the first access response information and is then stored. Compared with technologies of the prior art, the method and device for creating the session backup are advantageous in that the application session information can be directly stored in the user device corresponding to the access request without any special-purpose backup device, backup device deployment can be simplified, cost can be lowered, expenditure on primary and standby special-purpose line arrangement can be saved because no backup device is required, fully distributed type storage of the session information can be realized in a network device cluster environment, and a problem of limited cluster capacity expansion caused by information backup can be well solved.

Description

technical field [0001] This application relates to the field of computers, in particular to the technology of session backup. Background technique [0002] In the prior art, the session information corresponding to a cluster device that needs to be backed up is usually backed up in one or several devices corresponding to the cluster. For example, one or more central Control devices to achieve session backup, thus increasing the complexity of the entire cluster operation; at the same time, because the backup device itself is a full backup, there will also be storage data redundancy problems; and if multiple full backup devices are set , there will be dedicated line overhead between each device; further, when the cluster expands, the above-mentioned various drawbacks will become more prominent. Contents of the invention [0003] The purpose of this application is to provide a method and device for session backup. [0004] According to one aspect of the present application,...
