Claim One:
1. A method of detecting anomalous behavior of a network fabric, comprising: determining a baseline vector corresponding to nominal behavior of a fabric, the baseline vector comprising at least two different behavior metrics that are correlated with each other; disaggregating anomaly detection criteria into a plurality of anomaly criterion to be distributed among nodes of the fabric, the anomaly detection criteria characterizing a variation from the baseline vector, and each of the plurality of anomaly criterion comprising a function of a measured vector of behavior metrics, the variation calculated based on a variation function applied to a vector of measured behavior metrics having elements corresponding to member elements of the baseline vector; aggregating anomaly criterion statuses calculated by at least some of the nodes to detect anomalous behavior, each anomaly criterion status being calculated by a network node as a function of the node's anomaly criterion and a measured vector of the at least two different behavior metrics; and notifying a manager of the fabric anomalous behavior.
