Embodiment Construction

[0035] The client of the instant messaging system can realize functions such as registration, login after identity verification, friend status display, friend addition and deletion, sending messages, group messages, and file transfer; at the same time, the client can realize P2P chat and file sending.

[0036] The client can be a network application developed by VC++MFC under the Windows platform. All static data (data that needs to be saved when the service is stopped) is saved and organized in a database.

[0037] The functional modules of the client include user registration module, user login module, add / delete friend module, user message sending module, group message sending module, file sending module, and user logout module. When these modules communicate with the client or server, they parse the message according to the protocol analysis method agreed in advance, and then transfer the message through the underlying network communication module.

[0038] 1. The implementation...

Abstract

The invention relates to an instant messaging system and an instant messaging method. The method and the system realize the functions of user registration, user login, friend addition and deletion, friend data examination, message transmission, message mass texting and file transmission. A text messaging main server for managing and maintaining on-line users and realizing text messaging is designed around the basic text interchange function of instant messaging. In order to relieve the load of the server, P2P (Peer-to-Peer) transfer is tried for the transfer of basic text message of a client side by using a UDP (User Datagram Protocol), and an attempt is made to transfer the basic text message from the main server if the P2P transfer fails; and according to the scheme, the processing capacity and the response speed of the server are greatly improved.

Description

Technical field [0001] The invention relates to an instant communication system and method. The instant communication method and system realize the functions of user registration, user login, friend addition and deletion, friend information viewing, message sending, group message sending, file transfer and the like. Background technique [0002] With the popularization and development of informatization, the network is now not only more and more widely used in various enterprises and institutions, but also gradually integrated into everyone's life, gradually becoming an indispensable part of people's lives. Many school users consider using instant messaging to improve the quality of internal communication, streamline internal communication channels, and reduce internal communication costs. Especially universities are in urgent need. If school users all use several free instant messaging software, they will not be able to take full advantage of being in the same local area networ...
