Abstract

As optical networks proliferate, there is a growing need to address distributed multidomain provisioning. Although multi-domain operation has been well-studied in packet/cellswitching networks, the multilayer (granularity) circuit-switched nature of modern optical networks presents a unique set of challenges. This survey addresses control plane design for such heterogeneous infrastructures and describes new challenges in the areas of state dissemination, path computation, and survivability. Sample results from a recent study also are presented.
