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.

Abstract: A method to investigate congestion in a computer network may include network devices to route data packets throughout the network. The method includes, for example, sending a probe packet to network devices from a source node to gather information about the traffic queues at each network device that is examined by the probe packet. A routing table at each network device that receives the probe packet is based on the gathered information for respective each traffic queue.

Abstract: A system to manage data congestion in a computer network may include network devices to route data packets throughout the network. The system may also include a source node that sends data packets to any of the network devices. The system may further include a routing table at each network device that is updated by the source node, and the route the data packets are sent by any network device is based upon each respective routing table.
