Abstract
A method for hybrid arrival-occupancy based congestion management includes increasing a recent arrivals counter associated with a data flow from one or more sources in response to receiving a data packet from one of the sources and storing the data packet in a buffer including multiple storage units. The method includes determining if a buffer is congested, randomly selecting an occupied unit of the buffer and determining the source of the packet stored in the occupied unit of the buffer, generating a congestion notification message, sending the congestion notification message to the source of the packet stored in the occupied unit of the buffer if the recent arrivals counter exceeds a threshold value and decreasing the recent arrivals counter associated with the source of the packet stored in the occupied unit of the buffer and discarding the congestion notification message if the recent arrivals counter has a zero value.
