In this paper we explore the performance of SONET/SDH & OBS architectures connected as mesh topology, for optical metropolitan networks. Network throughput and protection to link failure. The results are based on analysis of simulations and we present a comparison between OBS architectures (with centralized & distributed scheduling schemes), SONET & NG-SONET. The OBS framework has been widely studied in past days because it achieves high traffic throughput & high resource utilization. A brief comparison between OBS & SONET is studied
