| 摘 要： | 对WDM光网络中的波长分配问题进行了研究,采用波长均衡分配的思路解决瓶颈容量对网络性能的影响,并给出了一种启发式算法--最大剩余瓶颈容量算法(Maximum Bottleneck Capacity,MaxBC).该算法把负载引起的波长损失均衡地分布在网络中,使得链路的信道容量受到的影响更小.通过仿真比较了MaxBC与MaxSum、RCL算法在网络拥塞概率等网络性能上的优劣.

| Abstract: | This paper reports that the current authors' researches on the wavelength assignment problem in WDM networks. The equalization policy is used to eliminate the influence caused by the bottleneck capacity for the network. And we propose a new heuristic algorithm entitled maximum bottleneck capacity algorithm (MaxBC), which distributes the wavelength loss to the whole networks. The simulation results show that MaxBC algorithm performs better in blocking probability than MaxSum and RCL algorithms. |
