A Framework for Differentiated Survivable Optical Virtual Private Networks

摘要

Wavelength division multiplexed (WDM) netowrks are matured to provide, scalable data centric infrastructure, capable of delivering flexible, value added, high speed and high bnadwisth services directly form the optical domain. Optical virtual private networks (OVPNs) make use of the concept of highly reconfigurable nature of lightpaths offered by WDM, to create secure tunnels of high bandwidth across the intelligent WDM optical transport network. An OVPN is a private connection between two or more edge devices (access nodes), that allows a group of clients to fully exploit the flexibility f the switched intelligent optical network.
