Provider Provisioned Internet VPN for Personal Communication Environment

This paper proposes a new method for provisioning of Internet VPN (Virtual Private Network), which will be used for ad-hoc personal activity and group work across users ’ networks over the Internet. In order to utilize Internet VPN in ad-hoc fashion, the users must configure the VPN routers and hosts in their networks correctly and rapidly. Because these configuration tasks require technical knowledge of the VPN, users often find it difficult and troublesome to accomplish the tasks, even though they are not new to the Internet. In some method to alleviate this difficulty, part of the configuration of VPN routers is provisioned from the management servers on behalf of the users. Unfortunately, it is not sufficient to enable ad-hoc usage. This is because the complex and time-consuming manual configuration of the VPN routers still remains and is required when joining the VPN. It is also because the hosts ’ configuration is out of their scope. In order to enable the ad-hoc usage, we propose a new method for provisioning of Internet VPN as an additional service of an ISP (Internet Service Provider)’s xDSL (x Digital Subscriber Line) or FTTH (Fiber To The Home) service. In our method, the terminal units for such services also serve as a VPN router and DHCP (Dynamic Host Configuration Protocol) relay agent, to minimize the configuratio
