Abstract
Methods implemented in a network are disclosed for dynamically distributing tasks of traffic anomaly monitoring and detecting traffic anomalies. The method starts collecting traffic statistics of large blocks of traffic flows as traffic aggregates. Based on the traffic statistics of traffic aggregates, a traffic anomaly is detected. Then for a traffic aggregate with a traffic anomaly, increased traffic sampling rate is applied to a smaller set of traffic flows within the traffic aggregate. If the smaller set of traffic flows does not contain a percentage of the traffic within the traffic aggregate, the sampling rate is further increase to an even smaller set of traffic flows until a small set of traffic flows are identified as the ones cause the traffic anomaly.
