Design And Implementation Of The Back-End Of Web Acceleration System

Nowadays,Internet has been progressing rapidly.The Web Application is the primary application of Internet.Along with the amount of users of Internet which increases rapidly,how to deal with the acceleration of Web Application becomes the chief problem of improving the service quality and increasing the access speed of users.The main solution of Web Acceleration includes hardware and software.The advance of capability of hardware is the ultimate measure which includes adopting more bandwidth and high-powered servers.But this solution could increase the cost greatly and bring new troubles of updating hardware.Considering with the relative ability of Network,software is just the way which could make a full use of the current system. Software which includes Web Cache and Proxy and so on could make effects a lot.Whether Web Cache nor Proxy are perfect and could make full use of Network Transport Protocols.Now under the condition of limited bandwidth,we supply one solution.It bases on the Web Cache mechanism of End-User,and makes full use of HTTP protocols and the unique feature of content hash values.The Acceleration Proxy is placed nearby the Web server.This solution could decrease the Repeat-Validation processes of Web objects which are requested by End-User.It could control the fluxes of Network and approach the goal of acceleration after the first time access.The Proxy could be divided into some function modules.And the back-end includes server interface module,memory management module,reverse name module,object process module,hash module.The main function of back-end includes communicating with Web Server,calculating hash values,memory maintenance and some logics.This solution could increase the speed of End-User access by experiment.
