Session synchronization method based on instant copying among cluster nodes

Abstract

The invention discloses a session synchronization method based on instant copying among cluster nodes. Session identification information is stored in a client, and storage of complete session information in the client is avoided, so that the potential safety hazard of exposure of user identity information can be prevented; meanwhile, in a process of sending a request to a server by the client, only the session identification information, instead of the complete session information, is carried, so that a volume of transmitted data is greatly reduced, and access frequency of the client to the server is improved; the session information is synchronized among the cluster nodes without being acquired from a database, so that a performance bottleneck caused by frequent use of the database is avoided; and a special session caching server also does not need to be used, so that development and deployment cost is reduced, and the session synchronization method has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of distributed architecture, and relates to a session synchronization method based on instant copy between cluster nodes. Background technique [0002] In the distributed architecture, the server uses a cluster environment. When the client accesses the server, how to synchronize the session information among the cluster nodes. At present, more mature solutions include: session synchronization based on cookies, session synchronization based on database, and session synchronization based on distributed For cached session synchronization, the above three methods all have deficiencies, as follows: [0003] 1. The session synchronization scheme based on Cookies, the steps are as follows, (1) When the client accesses the cluster service for the first time, the current cluster node creates session information for the client, saves the session information in the memory of this node, and saves the session information...

AI Technical Summary

Problems solved by technology

The main problem is that each request from the client needs to carry complete session information. If the session information is too large, it will take too long for the request to reach the server, which will affect the access efficiency; at the same time, since each request needs to carry Complete session information will increase the risk of exposing user information

The main problem of this solution is: If the access volume is too large, the frequent operation of the database will easily cause performance bottlenecks

The main problem of this solution is: since all session information is stored on the cache server, an additional cache server must be added during system deployment, and all operations on sessions must be performed on the cache server, which undoubtedly increases the Difficulty of system development and deployment
