Coordinated and unified control technology of IP and optical transport network for power services

Abstract

Based on the advantages of centralized,open and manageable of SDN (software defined networking) technology,a centralized unified control architecture and service coordination control mechanism of IP and optical transport networks for power services was proposed to realize power IP and optical transport network.Under the unified control architecture of IP and optical transport network,the IP layer flow table and optical layer flow table convergence mapping algorithm were proposed based on OpenFlow protocol,and the unified control interaction mechanism between IP and optical transport network was designed to improve power IP and optical transport network.Therefore,the support ability of IP and optical networks to power services can be greatly improved.
