Management of a Hub-Spoken Optical Transmission Network with the Point to Multi Point (P2MP) Topology

We have previously proposed and implemented a low cost and small form factor 8x10G optical transmission system based on digital-wrapper technology, which can be used as a Hub node device in the Point to Multi Point (P2MP) or Hub-spoken network application [1]. In this paper, we further develop a small remote edge node device which can complete the full scope work for the Hub-spoken network. Especially, we develop software for the control plane and network management system. This P2MP network management system is based on the fast FPGA processing and the OTN digital wrapper (ITU-T G.709) to provide in-band communication. Our test results show that we can simultaneously do network management from the Hub node to up to 8 remote small edge nodes, which has the great advantage comparing with using multiple OSC (optical supervising channel) of the traditional optical network.
