Research And Establishment Of Communication Network Risk Assessment Model

With the continuous expansion of communication network scale and the rapid increase of data,how to meet the needs of users and ensure the safe and reliable operation of communication network becomes more and more important.Communication network risk assessment management can effectively predict the impact of various risks on the communication network,improve the ability to avoid and cope with the risks,avoid network congestion or paralysis,reduce the probability of risk occurrence and the impact range of risk occurrence as far as possible,and ensure the stable operation of communication network and the normal provision of business.This paper applied in special environment risk(crowded places during holidays or big events environment,etc.)of the lack of a reliable and efficient communication network risk evaluation system and evaluation model of the problem,from the following several aspects of risk factors affecting the safe operation of the communication network are analyzed:the network structure,network quality risk,risk of network management,network security risk,environment risk,risk of supporting facilities,etc.At the same time,the identification and assessment methods of communication network risks and the establishment of indicator system are studied.This paper analyzes the importance of risk factors in communication network by using two kinds of algorithms combining subjective and objective weights,such as improved scale analytic hierarchy process(ahp)and projection tracing method.The evaluation index system and evaluation model modeling method of various risk factors analysis are put forward,the risk assessment model of communication network is established by the improved fuzzy mathematics algorithm,and the model is simulated by the real data of simulation environment.The results show that the two methods of improved scale analytic hierarchy process(ahp)and projection tracing method can correctly reflect the actual risk factors of the communication network after comparing the ranking of weight importance obtained by various analytical methods with the actual situation.The prediction and evaluation data output by the established evaluation model can accurately predict the operation status and risk of the communication network.It provides a reliable evaluation system and prediction model for the possible risks of the network in large-scale events or other special risk environments,and provides theoretical and technical support for the safe and reliable operation of the communication network.Figure[17]table[13]reference[84]...
