On an IP-centric optical control plane

This article presents an experimental study on adopting and integrating the existing IP protocols and mechanisms into an optical network control plane . Although there has been much research effort on the conceptual and functi onal requirements for the control of optical networks, this article focuses on the design and implementation of an optical control plane. The proposed control plane implements the key functions such as routing, signaling, pro tection/restoration, and quality of service.
