Comparative study of latency and throughput in OPS/OBS metro-access networks

We analyze and compare through network simulation the performance of medium range optical networks in mesh topology, operating in OPS/OBS modes under various link loads. The basic parameters network latency (delay), average number of hops (ANH) and packet loss fraction (PLF), are used as performance metrics. Based on node connectivity, a direct comparison can be established between these parameters in various network configurations and connectivity grades. By the same token, balance between cost and performance can be directly considered, rendering this analysis a useful and flexible network design and planning tool.
