In order to detect the network traffic anomaly better,it uses the cloud computing technology to study the network anomaly traffic detection method under the large data environment,and tests the network traffic anomaly detection effect. The abnormal network traffic detection task in large data is allocated to many sub task computing platforms. The results show that the average accuracy of the proposed detection method is improved by17. 08%,the false alarm rate is reduced by 65. 7%,the accuracy of the proposed method is higher,the false alarm rate is lower,and the detection performance is better. This method can meet the requirements of the network abnormal traffic detection under the current large data environment. Using the proposed network anomaly traffic detection method,the detection time is only 8. 81% of the conventional single network anomaly traffic detection method,which has better real-time performance compared with the conventional method.
