Research On NSIS NATFW Signaling Application In Mobile IPv6 Network

With the development of network technology and the popularization of notebook, mobile work becomes more and more important to people's life and work. Mobile IPv6 can help people realized this demand. Now, although firewalls are deployed widely, there are many problems on the integration of Mobile IPv6 and firewall to be solved. Those problems will encumber the Mobile IPv6's application and needs to be solved in time.In this paper, we introduce a new protocol-NSIS NATFW NSIS Signaling Layer Protocol. NSIS Signaling Layer Protocol proposes that we can change the firewall's ruler in the data path through signaling. So we propose that we can use the NSIS NATFW NSIS Signaling Layer Protocol to solve those problems. When the mobile node finds that he left the home link, we will introduce the firewall finding mechanism and the mobile node will implement the firewall detection procedure. If the firewall existed, NSIS Signaling Layer Protocol is needed which can communicate with these firewalls and instruct them to bypass these Mobile IPv6 messages. And in order to solve those problems, it can instruct the firewall to change their rules after authenticating. At the last, we analyze the feasibility of this protect.
