摘要: 提出了一种基于Hopfield神经网络新的路由算法, 它可以实现路由选择和波长分配的全局优化.用该方案进行路由选择所得到的最小波长数对业务模式具有相对稳定性, 而且减少了所用波长数目.

Abstract: We propose a routing algorithm based on Hopfield neural networks(HNN). The HNN routing scheme can get the optimal solution. The simulation results show that the algorithm is of parallel and robust. The minimal wavelength numbers the HNN gets is independent of traffic distribution and is robust. Comparing with other solutions, it also reduces the needed wavelength numbers.

Key words: wavelength division multiplexing, all optical networks, virtual wavelength path, Hopfield neural networks
