Research and Realization of Mobile IPv6 Protocol Software Based on Vxworks

This paper first introduces the principle of mobile IPv6 with the mobile node, communication node and home agent, illuminates the operating process when it moves from the home chain-circuit and designs the module structure that was disassembled into smaller ones for different function. Secondly, IP working process can be logically divided into three subsystem that are home agent subsystem, mobile node one and mobile communication one and realizes the IPv6 protocol stack for mobile characteristic by cooperating with each other. Then a design scheme is brought based on the real-time embedded operating system of Vxworks including software and hardware. Finally a mobile IPv6 protocol testing program is practiced in the protocol stack software system and the result shows that achieve the expectant effect.
