摘　　要：分析了现有指标不能评价大规模可扩展交换网络顽健性的问题,结合可扩展交换网络拓扑特性和故障模型,提出了一种基于故障影响的顽健性评价方法,并进一步提出了该方法评价指标的优化算法。通过实验比较了故障影响方法与现有方法对于可扩展交换网络的评价效果,结果表明故障影响方法可以有效地评价大规模可扩展交换网络的顽健性。Traditional robustness measurements are not suitable for large-scale scalable switch fabrics. Therefore, a novel robustness measure named failure influence was introduced, and improved algorithms for its metrics were also proposed. Experimental results showed that failure influence measurement can represented subtle robustness differences among various scalable switch fabrics. Failure Influence measurement was proved to be an appropriate robustness measurement for large-scale scalable switch fabrics.
