摘要:
 
Web服务是Internet上使用最广泛的服务,而Web服务的基础HTTP协议也一直不断在发展.随着互联网的迅速发展,当前协议的主要版本HTTP/1.1已经不能满足用户和开发者对响应速度和协议性能的需求.HTTP/2即超文本传输协议第二个版本还未普及.HTTP/2的主要目标是改进传输性能,实现低延迟和高吞吐量,致力于突破上一代的性能限制.对HTTP协议的发展历史进行了介绍,并对每个协议进行了分析与研究,着重分析了HTTP/1.1协议的设计缺陷.重点阐述了对HTTP/2的新特性以及其工作原理,以及如何改善HTTP/1.1协议连接利用率低、相同字段内容重复传输等缺陷.并设计了在不同网络协议环境下页面加载时间的对比实验,最终得出实验数据.实验结果表明,HTTP/2可以带来Web性能的提升,有助于改善互联网用户体验.
Abstract:
 Web Services is widely used in the Internet,and the HTTP(HyperText Transfer Protocol),the foundation of Web Services,iscontinuous to develop.With the rapid development of the Internet,the current version of the HTTP / 1.1 has been unable to meet the needsof the response speed and protocol performance for users and developers.HTTP / 2,the second version of the HTTP,is not yet available,and it aims to improve transmission performance,achieve low latency and high throughput,and break through performance limits fromprevious generation.For this,the developed history of HTTP is introduced,and each protocol is analyzed and researched,especially for thedesign flaws of HTTP / 1.1.The new features of HTTP / 2 and its working principle,and how to improve the defects like low utilization ratioof HTTP / 1.1 connection and the repeated transmission of the same field contents,are focused.After that,an experiment about thepage load time under different network protocols is designed and the result of that is obtained.According to the experiment,HTTP / 2 canimprove Web performance and is contributed to enhance the experience of Internet users.
