Analysis of dynamic traffic grooming in realistic scenarios

IP over Optical networks are emerging as one of the future architectures to support the growth of the Internet by sim-plifying the the network structure and layering. Many eval-uation works on these architectures, however, simply neglect the possible effects of a real network environment. In this pa-per we compare some overlay dynamic grooming algorithms in realistic scenarios from both the topology and traffic pat-tern point of view. As reference we present results where IP traffic is considered as constant bitrate sessions and high-light the differences between the models. Results show that the traffic model, scenario, and topology may have a larger effect than expected in grooming algorithms, specially when dynamic, reactive protocols are deployed
