Cloud architecture data center network abnormal traffic filtering algorithm based on improved grey clustering algorithm
Published 2023-07-01“…To avoid abnormal traffic affecting the safe operation of the cloud architecture data center network, it was necessary to filter the abnormal traffic of the cloud architecture data center network.The difficulty of filtering abnormal traffic varies under different signal-to-noise ratios and channel conditions.In order to ensure the filtering effect of abnormal traffic under different filtering conditions, a cloud architecture data center network abnormal traffic filtering algorithm based on improved grey clustering algorithm was proposed.A network traffic transmission model was built for cloud architecture data centers through time-frequency analysis, and network traffic sequences were collected.Weighted generalized distance was introduced to improve the grey clustering algorithm, and the improved grey clustering algorithm was used to calculate the optimal clustering results of network traffic sequence features, achieving traffic sequence feature extraction.The principal component eigenvalues of traffic sequence features were obtained through principal component analysis, two subspaces were constructed, and traffic features were mapped in a matrix manner to the two subspaces.Abnormal traffic was filtered based on the square prediction error of the mapping period vector and the threshold calculation results.The experimental results show that this algorithm can achieve feature extraction of data center network traffic sequences through clustering, effectively filtering abnormal traffic under different signal-to-noise ratios and channel conditions.When the signal-to-noise ratio of the network was 25 dB and the traffic was transmitted in a Gaussian channel, the filtering effect of abnormal traffic was more prominent.…”

STUDY ON RHEOLOGICAL BEHAVIOR AND CONSTITUTIVE MODEL OF TA17 TITANIUM ALLOY AT HIGH STRAIN RATE
Published 2022-01-01“…Based on the dynamic rheological characteristics of TA17 titanium alloy and considering the influence of the coupling between strain and strain rate on its flow stress, a new J-C constitutive model is constructed. based on the obtained experimental data, the model parameters are identified, the predicted values of the model are compared with the experimental data, and the two parameters of correlation coefficient(R) and average absolute relative error are introduced to evaluate the prediction accuracy of the constructed constitutive model.The results show that TA17 titanium alloy exhibits obvious strain hardening, strain rate strengthening and strain rate plasticizing effects, and its rheological behavior is dominated by strain, strain rate and the coupling between them. …”
