【摘要】 基于Jabber协议的P2P即时通讯系统以文字消息通讯和视频通讯为例。在文字消息转发过程中,用户先与服务器建立TCP连接并注册ID、IP个人资料等信息;初始化后,当向其他用户发送文字消息时,先将其发送给本地Jabber服务器,服务器从中读取目的主机的JabberID并解析出其IP地址,然后转发。视频通讯在服务器的协调管理下实现,用户双方采用UDP传输层协议,传送文件数据流不通过服务器,而是用户双方直接交互。更多还原

【Abstract】 Character message and video communication are taken as an example in P2P instant communication system based on Jabber protocol. In the process of character message, users establish a TCP connection with server and register personal data such as ID and IP message. After initialization, before sending the message to another user, the system will send the message to local Jabber server at first. The server reads the host computer Jabber ID and analyzes the IP address, then transmits. The video communication is realized under the server management. The users adopt UDP transport layer protocol. Data flow can not be passed the server, but the users communicate directly.更多还原
