The Multi-layer VPN Management Architecture

This paper proposes management architecture of multi-layer Virtual Private Network over the broadband network that will play an important role at the initial stage of broadband era. To provide flexible management capabilities with the administrator of the VPN, we adopt layering concept and abstraction mechanism to give a simple view of the real connection at service management level. The multilayer VPN management architecture we propose includes concept of Customer Network Management for subscriber's control capabilities of their own VPNs, and the information / computational model of VPN with emphasizing layering concept based on ITU-T G.803 and G.805. In addition, some advanced multi-layer VPN features and generic bearer connectivity model are presented. We also outline our early experiences about the implementations of the proposed VPN management architecture based on Common Object Request Broker Architecture and web technologies.
