Web-Based Customer Management of VPNs

The use of Virtual Private Networks (VPNs) is one of the major trends in the integrated broadband communications environment. Currently, the control and management of VPN resources is mainly supported by the provider of the bearer telecommunication services, and VPN customers have no control over these resources. The increasing importance of the broadband communication infrastructure in corporate operations and transactions is stressing the requirement for a customizable configuration, operation and management of VPN services. First, this paper discusses the evolution of VPN environments towards customized VPN configurations and goal-driven management of these VPNs. VPN service characteristics and management requirements are analyzed. Then, the paper introduces the proposed customer management architecture satisfying these requirements. The architecture is based on the multi-level virtualization of network resources through the partitioning of resources in the provider's shared communication infrastructure and the dynamic allocation of these resources to customers. A Web-based distributed approach is used for implementing the proposed customer management of VPNs.
