An Experimental And Analytical Study Of The Elasticity Of Model In Measured Complex Networks

Despite the rapid development of the network,every day there are thousands of network servers open or close.During its operation,the network is also constantly disturbed or damaged,thus resulting in performance degradation or even meltdown.People are more and more reliant on the network,but the impact of network incidents on people is increasing with this dependency.From the blackout in North America to the outbreak of the 20 th century financial crisis,we can see our dependence on the network and the huge losses that caused by the network meltdown For the Internet,the elastic structure is the new idea of evaluating the current network system.In previous studies,few researchers have conducted deep studies on the elasticity of complex networks,and the research on complex networks is limited to the theoretical verification of network's self-recovery.However,these problems are very important for the measurement of how complex networks defend itself against attack and decrease breakdown.So this article focuses on the complex network structure model and the Internet elasticityThis article mainly covers the following three aspects:1.Theoretical analysis of complex network.First start by the deep studies of complex network model,conducting separate formation and analyze each features of regular networks,stochastic networks,small-world and scale-free networks.Then follows the detailed introduction of index distribution,average path length and network clustering coefficient and different network attributes are analyzed by experiment.2.The article introduces the actual measuring method and measurement index of the network,analyzes the existing data at home and abroad,selects the most cost-effective measurement method to measure the Internet and provides the data for the characteristic analysis.By introducing the definition of network elasticity,the measurement data are experimented.The experimental results show that the ER random network is better than other networks in resilience of malicious attacks;BA scale-free network resilient recovery is better;regular network recovery robustness performance is the worst;WS small world is not obvious in features,its elasticity is between ER random network and regular network.In the Internet,the elastic recovery is mainly affected by the recovery measures,elastic connection can not make the network fully restored.3.Considering the static characteristics of the network,the article analyzes the network structure from the point of difference,and introduces the entropy index to the theoretical analysis and simulation experiment of the regular network,stochastic network,scale-free network and small world.The experimental results show that the entropy can reflect the structural characteristics of the complex network.
