WebSocket服务器推送技术的研究

The research of webSocket of push technology

采用传统的"请求—应答"模式,使用户从互联网中得到有用的数据信息非常困难,如果互联网可以主动将有用的信息发送到客户端,将会跟用户带来很大的帮助。笔者提出了一种服务器推送方案,该方案使用了基于WebSocket协议的服务器推送技术,还利用了复杂事件处理技术对数据进行快速处理。这种方案可以运用到即时通信系统、股票交易系统、即时订票系统、监控系统等多种实时系统中。

The use of the traditional ＂ request-response＂ model makes users getting useful information from the Internet difficult,if the Internet can take the initiative to send information to the client,it will bring a lot of help to users.this paper proposes a kind of server push scheme,this scheme uses the server push technology based on the WebSocket protocol,also uses the complex event processing technology for rapid processing data.This scheme can be applied to real-time communication system,example for trading system,real-time booking in the system,monitoring system and other real-time systems.
