Paper Abstract

The blocking performance of two types of all-optical networks: wavelength-selective (WS) and wavelength-interchangeable (WI) networks, is studied. Efficiency of different dynamic routing and wavelength assignment (RWA) algorithms, including adaptive routing algorithms and dynamic alternate routing algorithms, is investigated. Dynamic wavelength assignment combined with adaptive route selection algorithm is also presented and investigated. Numerical results show that multifiber WS networks may provide a viable and economical alternative to WI networks, and dynamic alternate routing algorithms is also a good substitute to adaptive routing algorithms. The presented dynamic wavelength assignment combined with adaptive route selection algorithms exhibit better efficiency than other ones. The study also shows that the efficiency of different dynamic RWA algorithms is dependent with different topologies, and the performance gain of wavelength conversion in regular topology is not as significant as in irregular topology networks, meanwhile, the efficiency of different dynamic RWA algorithms is closely related with the number of alternate routes.
