Abstract
A method, device, and system for network traffic analysis are provided. The method comprises obtaining traffic data of current time interval, recording the traffic data in a Chinese Remainder Theorem based Reversible Sketch (CRT-RS) based on a hash operation comprising Modulo operations, detecting abnormal buckets in the CRT-RS based on a change between the traffic data of current time interval and traffic data of previous time interval, and recovering abnormal source address associated information based on the abnormal buckets, wherein the modulus of the Modulo operations are selected from the modulus in Chinese Remainder Theorem (CRT) as pairwise coprime integers and the CRT-RS includes a plurality of buckets. The step of detecting uses a Modified Multi-chart Cumulative Sum.
