The Research Of Embedded Web Server Based On Dual Stacks

Embedded Internet is abroad applied to such home electric and industry control field. Especially, the embedded Web Server is developing quikly. On the background of the embedded home gateway, the embedded Web Server which can support IPv4 and IPv6 dual stacks on the low speed CPU with limited resources has been studied. The main contributions of the paper are as follow.At first, the research actuality of embedded Web Server is introduced. Compared with the variety of embedded Web Server technology, the feasibility of constructing Web Server on low-speed CPU is analysis from network access, encapsulation of sending data and analysis of receiving data. The architecture of the home gateway based on the embedded Web Server with dual stacks is structured. The thinking of subset partition and protocol optimization of TCP/IP is given. The IPv6 protocol is introduced into embedded system. So the system can run on IPv4 and IPv6 dual stacks and it will have aboard development foreground. The interactive processing of client/server in embedded Web Server has been studied .The constructing of http protocol and common gateway interface is discussed. Also, the safety of the system is illustrated in brief. At last, an example based on dual stacks embedded Web Server is given combined with the above-mentioned research content.
