Integrated Native-Ethernet Optical Ring Networks for Scalable Customer-Owned Application

We have proposed and examined one-by-one (O-O) and point-to-point (P2P) link integration scheme over native-Ethernet optical ring networks for scalable customer-owned metropolican area network application (CO-MAN). The 2-link integration enables us to construct economical networks, which was clarified by smaller number of optical transceivers required to provide IP services. The experiments clarified that the integration of the O-O and P2P links was successfully made through 35 km long fiber ring. The failure restoraion function was also confirmed to work properly, when the service ring failure occurred. All the packet transmissions were made on the native-Ethernet base, which allows the network administrators of the CO-MAN to manage the network in the same way as in the commonly-used LANs.
