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 evaluation is the basis of optical fiber communication network application. There are many factors that affect the safety of optical fiber communication network, and it is a complicated nonlinear variation system. Combining with the characteristics of optical fiber communication network evaluation index, a gray relational analysis and least squares support vector Machine Fiber Optic Communication Network Security Evaluation Model. Firstly, the gray relational analysis method is used to eliminate the contingency of the evaluation index of optical fiber communication network, optimize the evaluation index, and then fit the safety value of the least square support vector machine to the evaluation index. Finally, establish the evaluation model of optical fiber communication network security. The results show that different evaluation indexes have different influence on the evaluation results of optical fiber communication network, and the evaluation accuracy is higher than other evaluation models of optical fiber communication networks. This model has certain reference value for the research of optical fiber communication network security.
