摘要:

针对如何有效地限制网络随机故障对电力通信业务通道可用性的影响展开深入研究,将业务通道累积故障时间超出规定的概率模型定义为业务通道失效风险度,并对其作进一步研究. 波动变化是导致电力通信事件的根本原因,并推导出业务通道失效风险度的概率模型. 最后,将上述概率模型作为规划通道路由的决策参数,提出了面向可用性的电力通信业务通道路由选择算法,并通过仿真实验验证了其有效性.

Abstract:

How to limit impact of the availability of power communication services caused by random failures was presented. The business model of the cumulative probability of failure channel beyond prescribed time is defined as failure risk of service channel. A mathematical model for fluctuations of service channel availability was built and a probabilistic model of service channel failure risk was derived. This model proposed a planning decision parameter of channel routing algorithm based on random selection algorithm of failure risk degree of electric power communication service. Simulations verify the effectiveness of the algorithm.

Key words: power communication services channel, routing algorithm, failure risk, random process, availability
