摘要：

为克服B/S(Browser-Server)方式只能请求-应答传送数据（拉取方式）,而服务器不能主动推送数据到客户端浏览器的不足，研究了pushlet推技术，使服务器可将变化的数据主动地推送到客户端的浏览器中（推送方式），设计并实现了一个基于浏览器的网上粮价实时发布系统。该系统的服务器采用pushlet推技术，客户端采用动态网页技术。结果表明，采用pushlet推技术的通信流量是传统通信流量的15%,解决了传统B/S方式通信流量大、不能实时推送更新数据的不足。

Abstract:

To resolve the disadvantage of traditional server-client request-response mode，the pushlet technology which is a kind of network push technology is studied，with which the server can push variant data to client browser actively which is also called push mode. An online foodstuff-price real-time publishing system based on the pushlet technology is designed and realized. The system server uses pushlet technology, the client technology used is dynamic pages.By test and measuring, it is only 15% communication overload of tradition pulling mode by using the pushlet technology. The pushlet technology has solved the disadvantage that the traditional B/S mode network applications couldnt update real-time data and have heavy communication overload when updating.

Key words: pushlet networks, push technology, information publishing, real-time Web system
