Flexible, secure and cost effective in comparison to traditional solutions, IP-VPNs exhibit many of the traits enterprises are seeking today. Mobile VPN users have special requirements relating to resource adoption and customization. In this paper we have discussed how mobile agent technology can be applied to IP-VPN in finding a route for a tunnel with QoS features and also how can it provide service capabilities to mobile users. In our approach, we have considered the requirement from a group of VPN users. We have developed a framework to use active packets that can help us in discovering an optimal QoS route based on the available bandwidth and link cost. Also we have described an alternative approach for resource management between two agents. Taking into account, the structuring mechanisms enabled by standard mobile agent platforms, like regions, agencies grouped within regions, and places belonging to agencies, we have applied these structural principles to our target mobile communications environment. We have assumed that service providers have access to node’s control environment, algorithms and states. A possible framework for supporting mobile user groups after the deployment of the VPN issuggested in this paper. We have considered the concept of Place Oriented VPNs that are based on agent technology and can be built on top of existing VPN infrastructure.
