A static and OSPF routing integration scheme has been proposed to use 2 types of lightpaths: i.e. point-to-point and one-by-one lightpaths in IP-over-CWDM networks. The 2 types of lightpaths cause multipaths with different routing: i.e. static and OSPF routings, and therefore, a suitable scheme is necessary to assure that packets are routed by the shortest route, even if the routings are different...
Lightpath reconfiguration performance has been evaluated experimentally for regional IP-over-WDM network applications, making the network scalable and stable when traffic changes occur. The reconfiguration performance was examined in an experimental network with reconfigurable optical add/drop multiplexers (R-OADMs) to connect 4 nodes with bi-directional dual-fibers. The experiment was conducted by...
We have proposed a fully-native Ethernet (FNE) optical ring, integrating one-by-one (O-O) and point-to-point (P2P) links for customer-owned networks. A case study to design the proposed FNE ring clarified that required number of optical transceivers in the FNE ring is less than that in P2P links, providing a cost-effective solution. The experimental network of the FNE optical ring was constructed...
