DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware
A modular big data platform can solve 80% of the big data problems. To solve the other 20% of the problems, big data platform vendors must meet the special needs of industry customers for customized development. ZTE's DAP 2.0
