Abstract

A network switch comprises a plurality of optical physical transport layer resources and a control plane management engine capable of receiving, via a request over a network interface, at least one control plane provisioning policy that maps at least one upper layer resource to at least some of the optical physical transport layer resources. The control plane management engine provisions at least some of the optical physical transport layer resources for use by at least one virtual control plane, which operates according to rules of the control plane provisioning policy. The control plane management engine is configured to manage network traffic among the at least some optical physical transport layer resources and external networking nodes according to the at least one virtual control plane.
