[Abstract]:The importance evaluation of the power communication network can identify the key nodes and links of the network. It is of great significance to improve the network reliability and reduce the loss of the network. At present, most of the evaluation methods of the importance of the power communication network are based on the topology structure, and the methods of considering the business characteristics are relatively small, and are concerned about the effectiveness evaluation of the power communication network. Because the business in the power communication network has the specialty of industry, it is limited to measure the importance simply from the topology level. The development of this topic, considering the network topology and the influence factors of the business layer, make up the shortage of the existing research and effectively improve the accuracy of the evaluation. The method and the existing related achievements are deeply studied, and the evaluation methods of cross layer fusion are put forward. Firstly, the research results related to this subject are analyzed, and the evaluation methods of the power communication network are summarized. The topology parameters of the power communication network and the main requirements of the carrier and their performance requirements are analyzed, and the characteristic index method is refined. The comparison value of the importance of the power communication network is evaluated. Secondly, the natural connectivity is chosen as the network topology destruction measure to measure the damage degree of the topology layer after the failure of the network elements, thus the topology importance is obtained, and the importance of the node business and the link business importance are expounded in combination with the network model of the power communication network. In addition, the network weighted value of network elements is introduced into the calculation of natural connectivity. The weighted natural connectivity of the network is defined. The concept of the fusion importance and the link fusion importance of the fusion topology layer and the business layer is given according to the changes of the weighted natural connectivity after the link failure. In this paper, the importance evaluation of the cross layer fusion of the power communication network is presented. Thirdly, in view of the effectiveness evaluation of the power communication network, combined with the node and link importance as the index, the ADC method is used to establish the effectiveness evaluation model of the power communication network. The model is clear and helpful to the calculation. Finally, the experiment is carried out to verify the fusion evaluation method. Feasibility and effectiveness.
