Comparison and performance of routing protocols in SONET based networks

In this paper, comparison of various protocols used in the SONET based networks has been investigated in terms of the performance characteristics like end-to-end queuing delay, end-to-end link throughput, link utilization, etc. By creating a model to simulate the packet flow within a SONET DCC network characteristics of two routing protocols, the RIP (routing information protocol) and OSPF (open shortest path first) defined in the G.7712 standard are analyzed. Finally on comparing all the performance characteristics of the two routing protocol it is observed that OSPF protocol achieves better performance and is the least obtrusive on network operations.
