In this paper, the authors analyze the wavelength assignment problem in case of WDM optical networks. The random wavelength assignment algorithm is compared with the first - fit wavelength assignment algorithm. These two assignment strategies are also compared with wavelength conversion case. These comparisons are made on the basis of blocking probability, keeping the number of channels and number of links constant and the response is calculated by varying load per link (in erlangs). Blocking probability on a link is calculated by using famous Erlang B formula.
