Abstract: Constrained by the price and technology, not only the wavelength converters laid in WDM network but also the Wavelength Per Fiber (WPF) is limited. But there are usually some spare fibers in links, so it is important to make full use of these fibers to lower the blocking probability in WDM networks. This paper proposes a sparse multifiber and wavelength assignment algorithm based on dynamic traffic service WDM-networks. The simulation results show that by assigning sparse multifiber, the blocking performance can be obtained with fewer number of WPF. -
