Abstract :
In this study the design of reliable network topologies is applied to a typical metro network scenario. Results show that, with an increasing amount of traffic, ring topologies represent a less attractive solution and, on the other hand, highly connected DWDM mesh networks are required to grant the required level of throughput for bandwidth demanding applications and services.
