【摘要】：提高节点的负载容忍度可提高相依网络的鲁棒性,合理的负载冗余策略有助于降低成本。为研究相依网络节点负载容忍度与相依网络鲁棒性之间的关系及影响容忍度的因素,定义了节点负载容忍度和高容忍度节点比例两个参数,对负载失效和相依失效作用下相依网络的级联失效过程进行分析。结果表明在一定相依网络鲁棒性下负载容忍度存在上下两个阈值,且平均度是影响阈值大小的主要因素,同时证实了提高部分节点的负载容忍度也能提高相依网络的鲁棒性,可为设计相依网络系统提供借鉴。
[Abstract]:Increasing the load tolerance of nodes can improve the robustness of dependent networks, and a reasonable load redundancy strategy is helpful to reduce the cost. In order to study the relationship between node load tolerance and robustness of dependent network and the factors affecting tolerance, two parameters, node load tolerance and high tolerance node ratio, are defined. The cascade failure process of dependent network under load failure and dependent failure is analyzed. The results show that there are two upper and lower thresholds for load tolerance under the robustness of certain dependent networks, and the average degree is the main factor affecting the threshold size. At the same time, it is proved that increasing the load tolerance of some nodes can also improve the robustness of dependent networks. It can provide reference for the design of dependent network system.
