摘要
容错性是全面评价分布系统的重要方面。本文讨论了三种评价测度：节点／边连通度，生成树的数目及综合连通度。本文还给出了一个分析算例，算例表明，文中提出的综合连通度测度是合理的。
Fault tolerant ability is an important aspect for overall evaluation of distributed system(DS). This paper discusses three measures for the evaluation: node/edge connectivity, number of spanning trees and synthetic connectivity. A numerical example for illustration and analysis is given, and the synthetic connectivity measure presented by this paper is proved to be rational and satisfactory.
