Abstract:
In this paper, we propose the design of an electronic circuit that maps the whole optical system into the electronic domain and helps in intelligent routing by using simulated electrical network approach (SENA) method. The losses of a linear optical network due to the losses in propagation over the wavelengths and related optical components are modeled as resistances in order to simulate an equivalent electrical network. The concept used in SENA is that current flows in the path of least resistance, which provides a simulation tool to evaluate the optical path with a minimum loss. The developed model has been used to implement an intelligent routing algorithm to find the optimal path without going for time-consuming recursive algorithms for evaluating all possible path combinations. A novel modeling method incorporating some logic control circuitry and memory has been developed to achieve the best optimized path in WDM network
