A new dynamic wavelength assignment algorithm: load equalization algorithm

Routing and wavelength assignment is a key problem of WDM networks. A new dynamic wavelength assignment algorithm: load equalization algorithm is proposed. This algorithm equalized the load on wavelengths, maximizes the wavelength number reserved on each link; at the same time, it models the influence of assigning a wavelength on the network more accurately and minimizes the influence. The simulation results show that it performs better than other previously proposed algorithms in most cases.
