A Novel Layer 1 Virtual Private Network Provisioning Architecture in Multi-Domain Optical Networks

A novel multi-domain L1VPN provisioning architecture is proposed based on service plane of the adaptive multiservices provisioning platform. It can provide the inter-domain L1VPN services flexibly, and can establish different L1VPNs by analyzing different service characteristics and constraints. Moreover, the architecture the authors proposed was experimentally demonstrated in the AMSON testbed. Layer 1 Virtual Private Networks (L1VPNs) which is one of the potential value-added services of intelligent optical network has been a win-win solution for both Internet Service Providers (ISPs) and users.
