This paper proposes management architecture of a multi-layer
virtual private network over the broadband network that will play an
important role at the initial stages of the broadband era. To provide
flexible management capabilities with the administrator of the VPN, we
adopt a 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 the concept of customer
network management for a subscriber's control of their own VPN, and the
information/computational model of VPN with emphasis on the layering
concept based on ITU-T G.803 and G.805. In addition, some advanced
multi-layer VPN features and a generic bearer connectivity model are
presented. We also outline our early experiences with the
implementations of the proposed VPN management architecture based on the
common object request broker architecture and Web technologies

    ABSTRACT: Virtual private network (VPN) not only possesses the low cost, inexpensive fees, and excellent support advantages of the Internet, it also has the benefit of the security as the leased line. How to properly manage the VPN is an issue in which the enterprise IT engineers have to take seriously.This research is based on the new network management technologies such as policy-based network management, mobile agent, etc., to design a VPN monitor and management system architecture that contains high level management with low network traffic load. This system architecture integrates both VPN devices and general network devices, such the feature can integrate the monitor and manage the VPN and Intranet at the same time.The result of this research provides enterprises with a VPN architecture for monitoring and managing the enterprises, as well as to establish a prototype for the enterprise VPN monitor and management system. Such system architecture can effectively assist the semiconductor companies to monitor and manage their enterprise VPN in order to utilize the Internet resources, and to reduce the possible operation off time. The prototype system could proof the feasibility of the systematic architecture, it can automatically detect and activate the backup mechanism according to the preset management policy, and to achieve the effective and fast solution for the enterprise network problems.
