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 1 switching networks. Such Layer 1 VPN (LI VPN) services enable multiple customer networks to share a single transport network. In this work, we propose an architecture for LI VPN management. Our approach has been to use Policy-Based Management (PBM) to provide customers with some level of control and management over their LI VPNs. We also present a prototype implemented to validate the proposed architecture and discuss implications of policies for LI VPN configuration management.
