RESUMO

The present work covers the IP traffic grooming strategies in optical WDM networks. Using an entire wavelength to transport an individual traffic flow in a WDM network is inefficient. The problem known as traffic grooming consists in the multiplexing of different traffic flows in a single wavelength within a lightpath. The allocation of multiple traffic flows is performed by routing and wavelength assignment (RWA) and traffic grooming algorithms. In this work it is simulated the dynamic and elastic behavior of IP traffic directly on top of the optical layer. Based on the simulation results the effects of the IP traffic flow granularity on the network performance parameters are determined. The simulated topologies are the NSFNET and Kyatera. It is also established the correlation between the traffic flow granularity and the network performance parameters.
