A novel hypergraph structured optical network model

After entering the 21st century, the annual growth rate of network bandwidth demand is as high as 50-100%. In recent years, Automatic Switch Optical Network (ASON) have been widely studied as a new generation optical network technology with high speed, large capacity and ultra-long distance transmission. Among them, the main research focuses on improving the network bandwidth and transmission rate. However, due to the increasingly stable transmission medium and mode, the improvement of research results is very limited, especially in the current situation of a large number of network nodes. In order to improve the performance of optical network, a new structure model of optical network hypergraph is proposed based on Wavelength Division Multiplex (WDM) and Hypergraph theory. In addition, the routing based on parallel-path-based bandwidth algorithm (PPBA) demonstrates the excellent topology characteristics of the network, such as small diameter, low blocking rate and short forwarding delay.
