Abstract :
In this work we analyze the performance and sensitivity to link failure of metropolitan networks based on the technology of optical packet/burst switching (OPS/OBS). We use ring and mesh topologies to evaluate through analytical modeling and computer simulations the impact of link failure on each topology. We adopt the parameters average number of hops and packet loss fraction to evaluate network performance. It is observed that mesh topologies with triple-connection node configuration (3×3) are more robust; consequently in case of link failure the impact of lost data is minimum compared with the other topologies and configurations considered.
