Development Of Embedded Web Server On Cable Modem

Recently, high-speed broadband access technology has become the front line and key problem of communication technology field. HFC broadband access network is an effective solution to the problem.Cable Modem is the terminal device of HFC broadband access network, commonly uses serial terminal,telnet or SNMP methods to manage the equipment. But with the rapid expanding of Web technique, more and more network communication equipments and measure instruments have implemented the Embedded Web Server inside. User and operator can manage the equipment by using Web browser to visit the web pages in Embedded Web Server. Due to support of multiple terminal operating systems and universal user interface, adopting the Embedded Web Server technique is a trend of embedded device's development.The author developed and implemented an Embedded Web Server on the Cable Modem by using pSOSystem real-time operating system as development platform. The server can deal with two request operations specified in HTTP: GET, POST. Then the server offers a manage mode based on web.At the beginning of this thesis, the author analyses the architecture of HFC and the principle of Cable Modem. Then, the author expounds pSOSystem as the software development platform of Cable Modem. Based on the analysis to the HTTP protocol and the research on network server, the author brings forward the development principle and software flow chart of Embedded Web Server, emphatically analyses the software development about the network interface of web server, the establish of IP stack, web server thread, the startup of web server and other main functions of web server...
