The Designs of Interconnected Optical Ring Networks

Optical ring networks have been widely implemented as the major metro network architectures. However, as the network coverage expands, the system performance of the single ring structure degrades significantly. In this paper, we propose an interconnected ring topology to enhance the network throughput and efficiency. The carried out simulation results have revealed the superiority of employing such an interconnected architecture. We also discuss the increased complexities and fairness issues induced by such design.
