Paper Abstract

All-optical networks, employed wavelength division multiplexing (WDM), is the core part for the next generation backbone networks, the technology concerning how to make the network stronger is the key research topic on the construction of WDM networks. We study the protection mechanism for WDM works with mesh topologies and discuss the algorithms for virtual-circle protection in this paper. The algorithms discussed as following can be applied to networks with arbitrary topology, and meanwhile, avoid searching issue in the "Hamilton" circle.
