Algorithm of CVFDT (concept-adapting very fast decision tree) in CDN (content delivery network) operation and maintenance prediction on basis of Storm

The invention discloses an algorithm of a CVFDT (concept-adapting very fast decision tree) in CDN (content delivery network) operation and maintenance prediction on the basis of Storm. The algorithm is mainly used for the field of CDN operation and maintenance; the Storm topology is subjected to corresponding modeling; the possibility that a magnetic disk or a cutter blade server applied at high intensity fails is predicted. Therefore the user feeling is improved; the service quality is improved. Meanwhile, a more reliable standard is provided for the aspects of data migration by background personnel, dynamic load regulation and the like. 本发明公开了基于Storm的CVFDT在CDN运维预测中的算法，主要用于CDN运维领域，通过对Storm拓扑进行相应建模，对高强度的应用下的磁盘或者刀片服务器出现故障的可能性进行预判。从而提高用户感受，提升服务质量。同时也为后台人员迁移数据，动态调整负载等等方面提供了个更可靠的标准。
