Web页面获取延时模型研究

Researches on Web Page Access Latency Model

由于Internet的复杂性,至今还没有一个精确的模型用来描述Web的性能.要想得到一个比较精确的Web页面获取延时模型,必须以传输层的TCP模型为基础,再结合HTTP层的WRDM模型来建模.文中提出了一个结合TCP和HTTP性质的数学模型和算法.从模型出发,指出TCP、HTTP等协议以及网络上各种算法的改进方向.

As yet,there is not such a precise model to depict the Web performance because of the complex of Internet.To obtain a more precise latency model via Web page,it is necessary for modeling to base on TCP model of the transport layer and combine with WRDM model of the HTTP layer. A new mathematics model and algorithm which combines TCP with HTTP is proposed. Starting with the model,the paper has pointed out the directions of TCP and HTTP protocols and various algorithms on the network.
