NSIS-Based Firewall Detection in Mobile IPv6

Nowadays, most firewalls which are deployed in networks are not compatible with mobile IPv6. And to modify the configuration of firewall by using NSIS signaling is one of signaling solutions. In this paper, the purpose is to resolve the problems which are in mobile IPv6 network environment during the traversal process by using NSIS signaling. We introduce a new method that can reduce the complexity of signaling, decrease the time delay in network. In addition, the process of firewall detection and the process of firewall traversal are both based on NSIS, which can make NSIS more consummate.
