A management architecture for layer 1 VPN services

A distributed control plane architecture enhances transport networks with dynamic and flexible connection control. As a result, it allows the provisioning of advanced connectivity services, like virtual Private Networks (VPNs), on layer I switching networks. Such Layer 1 VPN (L1VPN) services enable multiple customer networks to share a single transport network. In this work(1), we propose an architecture for L1VPN, management. Our approach has been to use Policy-Based Management (PBM) to provide customers with some level of control and management over their L1VPNs. We also present a prototype implemented to validate the proposed architecture and discuss implications of policies for L1VPN configuration management.
