CONGESTION ESTIMATION

An apparatus comprising a plurality of flow model circuits, a categorizer circuit, and a plurality of link model circuits. Each of the flow model circuits may be configured to generate a respective flow measurement signal in response to data packets received from a plurality of links on a network. The categorizer circuit may be configured to present a plurality of link measurement signals, each in response to one or more of the plurality of flow measurement signals. Each of the link model circuits may be configured to generate a respective congestion estimation signal in response to (i) a respective one of a plurality of model parameter signals, (ii) a respective one of the plurality of link measurement signals, and (iii) a respective one of a plurality of score signals. Each of the congestion estimation signals may represent a congestion level of a respective one of the links.
