Verizon experience with NG Ethernet services: evolution to a converged layer 1, 2 network

This article presents Verizon's experience with deploying metro Ethernet services and some of our laboratory activities related to the convergence of layer 2/1 networks. Such convergence leverages the existing SONET and optical transport network infrastructure, and integrates layer 1 and layer 2 transport, control, and management planes within the network. Integrated service provisioning is featured, including service logic and policy that controls the admission, path selection, and transport bandwidth adjustment requirements of provisioning an Ethernet virtual connection within the metro Ethernet network.
