Influence of topological connectivity for transport in optical networks with amplified photonic switches

The present work analyzes the performance of optical networks with architecture based on mesh topology and photonic switching. We describe the analytical calculus based on theory concepts to estimate the standard performance and results of computer simulation to validate our expectations. The main adopted parameters for this analysis are the packet loss fraction (PLF) and average number of hop (ANH). We observe that the combination of these elements leads to a consistent account of performance, in terms of network traffic and packet delivery for optical packet and burst switching (OPS/OBS) metropolitan networks. Results show that combination of highly connected mesh topologies having an ingress e-buffer present high efficiency and throughput, with very low packet loss and low-latency, ensuring fast data delivery to the final receiver.
