Communication network vulnerability analyzing system for large-scale area fault and working method of communication network vulnerability analyzing system

Abstract

The invention discloses a communication network vulnerability analyzing system for a large-scale area fault and a working method of the communication network vulnerability analyzing system. By means of the network vulnerability analyzing system, the level of the effect to a communication network topology design and network cabling from natural disasters (such as earthquakes and water flood), man-made sabotages (such as purposeful EMP attack and fisher trawling) and other regional faults related to geographic positions can be assessed, and the statistical behavior characteristics including average fault link capacity, the end-to-end flow change property and other properties under the regional fault situation of the network are found. According to the network vulnerability analyzing system, the fault region affecting the network mostly can be positioned through the topological information of the physical network, and then the network protecting design is guided. The network vulnerability analyzing system provides a visual interface environment, and can definitely indicate the vulnerability of the system, help communication network designer and maintainer to plan ahead and build the network service with higher robustness.

Description

technical field [0001] The invention relates to network vulnerability analysis, especially analyzing the behavior characteristics of physical network topology under large-scale area faults, and simultaneously locating the potential fault area position that has the greatest impact on the network. Background technique [0002] Computer networks have become the main means of communication in today's society. As people's dependence on the network increases, users have higher and higher requirements for network reliability. On the other hand, due to the rapid development of the network itself, the impact of large-scale regional failures, such as natural disasters and man-made damage on the network is becoming increasingly prominent, and its frequency and degree of damage are on the rise, which has become a major problem that cannot be ignored affecting network reliability. one. [0003] Network vulnerability analysis can help designers and maintenance personnel understand the d...

Problems solved by technology

The location, shape and scope of the failure are unknown, and the impact of network equipment on the failure is also difficult to predict

Simply following the traditional analysis method on the logical network and using the deterministic regional fault model will over-simplify the vulnerability analysis of the network and fail to reflect the important characteristics of regional faults, resulting in the failure of network recovery strategies or over-investment in network protection.
