Abstract :
Multi-wavelength conversion is a feasible technique to realize optical signal replication. However, there are little work to study the wavelength assignment and network performance in the optical network employing multi-wavelength conversion. In this paper, we investigate the wavelength assignment algorithm in optical networks with multi-wavelength conversion. To improve the resource utilization, multi-wavelength converters are shared at each node in the network. The main object of the proposed wavelength assignment algorithm is to maximize the acceptable destinations and minimize the wavelength conversion at the same time. Simulations are conducted to compute the blocking probability. It can be found that 25% multi-wavelength converters are sufficient to guarantee almost the same performance with full configuration of converters at each node, even when the traffic load is extremely high.
