Modelling and analysis of optical packet switched networks in mesh topology

In this work we develop a performance evaluation for optical packet switching network (OPSN) architecture and optimized mesh topology with (OMT) comprising 2times2 optical bufferless nodes configuration. The analysis is carried out with analytic modeling and simulation methods using as basis for comparison the Manhattan Street topology with 16 nodes (MS-16). This work comes to validate our simulation methods, the search for optimized topologies, and the analytic modeling comes to clarify some important conceptual aspects of packet switched network operation. Besides the performance analysis, we have conducted an estimate of packet delay based on average number of hops, which contributes to QoS evaluation.
