Interworking Between OpenFlow and PCE for Dynamic Wavelength Path Control in Multi-Domain WSON

Free registration required

Executive Summary

OpenFlow, as a promising control plane technique for a software-defined network, has been attracting much attention from both academia and industry in recent years. In, an OpenFlow-based control plane for a single domain Wavelength Switched Optical Network (WSON) has been experimentally presented. However, to the best of the authors' knowledge, the usage of the OpenFlow protocol/architecture to provision a wavelength path in a multi-domain WSON has not been addressed so far. They experimentally present the seamless interworking between OpenFlow and PCE for dynamic wavelength path control in multi-domain WSON, assessing the overall feasibility and quantitatively evaluating both the path computation and light-path provisioning latencies.
