1.说明

类似于QQ的局域网聊天软件,包括服务器端和客户端程序,采用tcp/ip socket多线程编程,服务器端主要负责客户端用户的注册登陆,用户资料的获取.客户端负责与其他客户端进行信息控制与传递(包括聊天和传送文件).

2.特点

a.采用tcp非udp的socket编程,保证传输的稳定性和实时性.

b.在同步操作时大多数采用了多线程和超时控制.例如:在传送文件的同时能继续聊天.

c.服务器只负责用户登陆,查询,修改用户的基本信息和实时的在线用户列表.而不参与客户端之间的信息传递.

d.每个客户端既是聊天的发起端,又是接收端,实现了多点同时聊天和传送文件. -1 Descr iption

LAN chat software like QQ, including server and client program, using tcp/ip socket multithreaded programming, registration login server is responsible for client users, access to user data The client is responsible for client information with other control and delivery (including chat and transfer files).

2 Features

a. using non udp tcp socket programming, to ensure stability and real-time transmission.

. b synchronous operation when most uses multithreading and timeout control such as: transferring files at the same time continue to chat.

c. servers are only responsible for user login, query, modify the user s basic information and real-time online user list. not participate in the transmission of information between clients.

d. Each client is both initiator chat, but also the receiving end, to achieve a multi-point simultaneous chat and transfer files.
