Layer 1 VPN NMS Based on Each VPN Customer

A virtual private network (VPN) makes it possible for a customer to use a wide range network by borrowing a provider network. In addition, by recent emergence of the layer 1VPN (L1VPN), more customers require to control the end-to-end path setting on VPN by using path computation traffic engineering. We propose a customer-based L1VPN network management system (NMS) that is separated from a provider NMS. This customized NMS enables each customer to explicitly control a customer IP path from an end-to-end point of view. The separation of each customer L1VPN NMS from a provider NMS also releases the provider NMS from a huge burden. We implement a management and control function in an L1VPN NMS by using enterprise java beans (EJBs). Then, we discuss and evaluate the merits of the proposed NMS.
