  • At the network layer, several constraints must be taken into account when calculating multicast routing and wavelength assignment. The constraints mainly include the following four aspects: sparse light splitter constraints, wavelength continuity constraints in WDM optical network, power budget constraints and sparse wavelength convert constraints. So far, most papers analyzed only one or two of these constraints respectively. This paper illuminates these constraints in detail first and then brings forward a heuristic algorithm with multiple constraints. Finally, designs two simulations on CERNET and NSFNET network topology. The results of the two simulations indicate the validity and feasibility of the algorithm.
