Problems solved by technology

Most of these methods only consider the characteristics of the network topology itself when analyzing the importance of nodes, but ignore the impact of network bearer services on the importance of nodes, so the conclusions drawn are sometimes one-sided and cannot accurately reflect the characteristics of nodes in the communication network.

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0038] like figure 1 As shown, a method for identifying the importance of nodes in a power backbone communication network includes the following steps:

[0039] S1. According to the network topology of the actual power backbone communication network, a network model corresponding to it is constructed, and the network model can be expressed as follows in graph G:

[0040] G=(V, E);

[0041] where V={v 1 ,v 2 ,...,v N} is a collection of nodes in the electric backbone communication network, the nodes are mainly optical transmission equipment, N is the number of nodes, E={e 1 ,e 2 ,...,e M} represents the collection of link...

Abstract

The invention discloses a power backbone communication network node importance identification method. The power backbone communication network node importance identification method comprises the following steps: constructing a network node difference matrix based on a power backbone communication network topological structure in combination with complex network heterogeneity; constructing a network link difference matrix by taking the link traffic as the weight of the link according to the characteristics of the communication service; and by comprehensively considering the network node difference and the link difference, constructing a network heterogeneity matrix, and calculating the node importance degree through the heterogeneity matrix. According to the power backbone communication network node importance identification method, the degrees of the nodes and the contribution of degree distribution to the network are considered; meanwhile, the service flow borne by the link connectedwith the communication node is fused; the contribution of the service to the importance degree of the node is reflected; and the algorithm involved in the method is simple in calculation form, low incomplexity and capable of well adapting to node importance degree identification of the large-scale electric power backbone communication network.

Description

technical field [0001] The invention relates to the technical field of power communication networks, in particular to a method for identifying the importance of nodes in a power backbone communication network. Background technique [0002] With the development of communication technology and the rapid growth of information transmission requirements, the network scale of communication network is getting larger and larger, its structure is becoming more and more complex, and the reliability requirements of the network are also getting higher and higher. The communication node is the core element of the communication network, which is responsible for the function of uplink and downlink services and service forwarding. Its importance is closely related to the location of the node in the network and the security level of the carried service, service quality and service quantity. If the core nodes in the network are damaged, it will affect the normal transmission of services. Whe...
