分布式即时通讯系统的设计与实现

In recent years, people communicate with each other through instant messaging software, instant messaging software has played a huge role in making the establishment of new interpersonal relationships, expanding the network to improve work efficiency. But the traditional instant messaging system in the face of high concurrent requests is easy to cause the problem of data storage and security, according to the actual project, the overall design of a distributed instant messaging system, then according to the different function module, focuses on the analysis of the system server module such as terminal services, control center, routing, data cache and detail the design idea, this scheme is easy to implement, and have a good scalability, can effectively solve the system in high concurrency , a large amount of data query and operation efficiency, improve the response speed of the database security and scalability and communication applications, ,I hope this scheme can provide cerain reference and some ideas a for the development of related developers.
