基于事故链的光纤网络通信传输脆弱性评估方法

Fiber network communication transmission vulnerability assessment method based on accident chain

为了提高光纤网络通信传输的稳定性和安全性,需要对光纤网络通信传输的脆弱性进行评估。采用当前方法对光纤网络通信传输的脆弱性进行评估时,存在预测精准度低、评估误差率高和评估效率低的问题。在事故链的基础上提出一种光纤网络通信传输脆弱性评估方法,将光纤网络的主网作为研究对象,以增幅低频震荡和等幅低频震荡作为最终结果,生成光纤网络通信传输的事故链。在光纤网络潮流转移、网络频率和低电压变化的基础上,结合故障发生后产生的后果和事故链环节发生的概率,通过事故链构建光纤网络通信传输的脆弱性评估模型,根据脆弱性评估模型对光纤网络通信传输的脆弱性进行评估。实验结果表明,所提方法的预测精准度高、评估误差率低、评估效率高。

In order to improve the stability and security of fiber-optic network communication transmission,it is necessary to evaluate the vulnerability of fiber-optic network communication transmission. When the current method is used to evaluate the vulnerability of fiber-optic network communication transmission,there are problems of low prediction accuracy,high evaluation error rate and low evaluation efficiency. Based on the chain of accidents,this paper proposes a vulnerability assessment method for fiber-optic network communication transmission. The main frame of the fiber-optic network is taken as the research object,and the low-frequency oscillation and equal-amplitude low-frequency oscillation are used as the final results to generate the accident chain of the fiber-optic network communication transmission. Based on the trend of fiber network power flow,network frequency and low voltage,combined with the consequences of the failure and the probability of the accident chain,the vulnerability assessment model of the fiber network communication transmission is constructed through the accident chain,according to the vulnerability assessment model. Evaluate the vulnerability of fiber-optic network communication transmissions. The experimental results show that the proposed method has high prediction accuracy,low evaluation error rate and high evaluation efficiency.
