摘要: This work proposes a highly reliable hybrid star ring bus architecture (SRBA) for broadband wavelength division multiplexed (WDM) regional access networks A delta slat network on the top level acts as high capacity Punk infrastructure whose weakness in reliability is overcome by the self healing function of the concatenated ring item ark on the lower level The ling network is divided into several delta regions where the traffic load inside each region is unified to minimize the backup resources required in the network On the bottom loci considerable bus subnets are constructed to serve end users The idea of A bands is introduced to efficiently manage wavelength carriers used in the network Moreover by means of the automatic protection switching (APS) systems in all the optical network units (ONUs) a minimum hop rerouting protection scheme against fiber failure(s) is designed Specifically is e cam out an experimental network to demonstrate the feasibility and survivability of the proposed architecture (C) 2010 Wiley Periodicals Inc Microwave Opt Technol Lett 53 102-108 2011 View this article online at wileyonlinelibrary com DOI 10 1002/mop 25628
