摘要
安全评价是光纤通信网络应用的基础,影响光纤通信网络安全的因素众多,而且是一种复杂的非线性变化系统,结合光纤通信网络评价指特点,提出一种灰色关联分析和最小二乘支持向量机的光纤通信网络安全评价模型。首先通过灰色关联分析法消除光纤通信网络评价指标偶然性,对评价指标进行优选,然后对最小二乘支持向量机拟合安全值与评价指标的关系,最后建立光纤通信网络安全评价模型。研究结果表明,不同评价指标对光纤通信网络安全评价结果影响差异性比较大,评价精度要高于当前其它光纤通信网络评价模型,该模型对光纤通信网络安全研究具有一定的参考价值。
Safety assessment is the basis of the application of optical fiber communication network, there have plerty of factors that affect the safety of optical fiber communication network, and it is a complex nonlinear system, a safety assessment model for optical fiber communication network is proposed in this paper which is grey correlation analysis and least squares support vector machine. Firstly, gray correlation analysis is used to eliminate and select the evaluation index, and secondly the security evaluation model of optical fiber communication network is established by using least squares support vector machine. The research results show that different evaluation indexes have great influence on the safety evaluation results of optical fiber communication network. The evaluation precision is higher than the current evaluation model and the model has some reference value for the research of optical fiber communication network security.
