Abstract
Embodiments of the invention relate to providing quantized congestion notification (QCN) in networks. One embodiment includes a method that includes determining a traffic flow congestion by a particular congestion point (CP) unit of multiple CP units that communicate with at least one end unit, at least one reaction point (RP) unit and at least one controller in a network. A first congestion notification message (CNM) and a second CNM are generated by the particular CP unit. The particular CP unit sends the first CNM directly to the controller and the second CNM directly to the RP unit. Traffic flow is managed among the multiple CP units by the controller based on the first CNM.
