Optical packet/burst switching node architecture with WDM hierarchical issues

Applications with optical packet switching (OPS and OBS) offer potentially large capacity due to significant increase in optical channel granularity and use. Thus, simulation studies on optical packet/burst switching node architectures, as presented here, are an important strategy to evaluate new designs, joined with provision of quality of service (QoS) and differentiated traffic support. This work presents an innovative node architecture for both OPS/OBS metro-access optical nodes, which has issues on WDM for the hierarchical network core integration.
