Abstract :
In this paper, we propose a colored multigraph model for the temporarily available wavelengths. Based on this colored multigraph model, a polynomial time algorithm with complexity O(N2) is also proposed to develop an integrated dynamic routing and wavelength assignment, where N is the number of nodes in a WDM network.
