【摘要】：电力通信网是智能电网的重要支撑网络,针对如何对其脆弱性进行综合、有效评价的问题,该文提出一种基于信息熵的电力通信网脆弱性跨层综合评价方法。首先给出了一种业务重要度计算方法,并将业务重要度作为网络参数,在业务层建立网络模型,定义边业务重要度(EBI)作为边在业务层的重要性指标;然后综合考虑网络的业务层、传输层和物理层,定义了边跨层重要度(ECI),进而将边跨层重要度的全网信息熵-边跨层信息熵(ECE)作为电力通信网脆弱性的评价指标;最后,以某实际电力通信网络为仿真背景,在不同路由策略下,通过对比网络脆弱性曲线和信息熵值的变化,证明了该方法对电力通信网脆弱性评价的有效性。该方法不仅限于电力通信网,还可推广至其它非一致性业务的承载网络。
[Abstract]:Power communication network is an important supporting network of smart grid. Aiming at the problem of how to synthesize and evaluate its vulnerability effectively, this paper presents a comprehensive evaluation method of power communication network vulnerability based on information entropy. First, a calculation method of service importance is given, and the service importance is taken as the network parameter, the network model is established in the service layer, and the edge service importance (EBI) is defined as the importance index of the service layer. Then considering the service layer, transmission layer and physical layer of the network, the paper defines the edge cross layer importance (ECI), and then takes the whole network information entropy (ECE) of the edge cross layer importance as the evaluation index of the power communication network vulnerability. Taking a real power communication network as the simulation background and under different routing strategies, the effectiveness of this method in evaluating the vulnerability of power communication network is proved by comparing the network vulnerability curve and the change of information entropy. This method is not only limited to power communication networks, but also can be extended to other non-uniform service carrying networks.
