Description
Summary:Multiple fiber ring (MFR) networks employing the optical path (OP) concept are discussed to realize robust networks. The architecture is superior to that discussed in several testbeds, with respect to fault recoverability. Both the OP based and non-OP based MFRs can develop several architectures, each of which provides different performance regarding network resource utilization. The required node system scale can be a good measure in determining the network performance. Network design simulations, varying path distribution patterns, have been performed and they elucidated the criteria for selecting the most suitable architecture in terms of resource utilization.
