Design And Implementation of Shortest Path For Wavelength Routed Networks

According to a quick growth of the bandwidth capacity of WDM network, traffic damage due to a failure of network components is becoming unacceptable. To overawe this problem, a protection method that prepares backup light paths for each working path is now considered to improve reliability of networks. In this paper, it proposes an energy efficient routing in WDM passive optical networks. Routing means to provide a connection between source and destination node. Optimal Routing can increase efficiency of wavelength routed optical networks. Provisioning a connection in such a network includes defining a time-slot assignment, in addition to route and wavelength. Then their effect on performance parameters like energy has been calculated. The results show that it reduces the energy consumption. The simulations have been done with MATLAB tool and Its GUI. KeywordsShortest Routing, path in Networks, WDM Networks, Efficient Routing.
