Embedded Web System And Achieve

21 century is the embedded system times, the apparatus and equipment people use in everyday life are all embedded in effective microprocessor. Embedded system has already been widely used in industrial controlling system, electronic production, communication apparatus, medical equipment, military equipment and so on. But most of them are not been covered by Internet.Web technology provides a kind of new method to organize information using hyper link which is convenient for reading, hence it changes the way by which people obtain information and accelerates the development of Internet. HTTP is the key protocol of Web technology which is most popular today, and it is the basis on which communicating between Web browser and Web server. All of these established the theoretical basis for implementation of the embedded Web server.HTTP uses TCP/IP as their underlying transport protocol, which is based on the SOCK_STREAM. After finishing the HTTP communication, Web server and browser transfer their Socket provided by system, then execute Socket (), Bind (), ListenO, Accept (), Recv(), SendO, Close (). But in embedded web circumstance, the embedded web server is restricted by resource, expend, cost and so on, so the Socket provided by system may be programmed by the user.
