Preconfigured protection cycles or “p-cycles” can attain high capacity efficiency and fast protection switching times when deployed in WDM mesh networks. We consider the survivability of p-cycles in presence of multiple failures which can occur in larger networks.

Single-hop wavelength division multiplexing (WDM) ring networks operating in packet mode are a promising architecture for the design of innovate Metropolitan Area Networks. They allow a cost-effective design, with a good combination of optical and electronic technologies, while supporting features like restoration and reconfiguration that are essential in any metropolitan scenario. In this arti...

We consider the problem of traffic grooming in wavelength division multiplexing networks. Our objective is to minimize the required number of electronic add-drop multiplexers. We investigate the problem of efficiently provisioning connections of different bandwidth granularities in a heterogeneous WDM mesh network through dynamic traffic grooming schemes under traffic engineering principles. We...
