| 摘 要： | 针对WDM网状网中业务量矩阵不确知情况下(hose业务模型)的鲁棒资源配置问题,进行了抗毁设计,采用专用通道保护策略,网络设计的优化目标为全网代价最小。提出了DPP-MRU和DPP-MST两种启发式算法,并通过计算机仿真分析,从两种算法在USANET-hose和ITANET-hose模型下的全网代价比较,证实了最大资源利用率算法具有较小的全网代价。

| Abstract: | In the paper, considering the problem of robust resource provisioning in WDM mesh networks under the uncertain traffic matrix (hose model), we design the resilient WDM mesh networks. The strategy of dedicated-path protection is used. We propose two heuristic algorithms whose optimization objective is to minimize total network cost. Some comparisons for these algorithms by simulations, show that the maximal resource utilization (MRU) algorithm has fewer total network cost. |
