Network traffic arbitration based on packet priority

A network router, comprising:

• a controller configured to:
• receive two or more network packets over two or more input ports;
• during an observation window, record traffic parameters of the two or more network packets in a traffic history table, the traffic parameters including a Quality-of-Service (QOS) priority value for a network packet of the two or more network packets;
• and
• based at least in part on the traffic parameters recorded in the traffic history table, including the QoS priority value, calculate arbitration weights for each of the two or more input ports for a weighted round robin arbitration process.

A method for network traffic arbitration, the method comprising:

• at a network router, receiving two or more network packets over two or more input ports;
• during an observation window, recording traffic parameters of the two or more network packets in a traffic history table, the traffic parameters including a Quality-of-Service (QOS) priority value for a network packet of the two or more network packets;
• based at least in part on the traffic parameters recorded in the traffic history table, including the QoS priority value, calculating arbitration weights for each of the two or more input ports for a weighted round robin arbitration process, wherein an arbitration weight for the network packet is proportional to the QoS priority value of the network packet;
• and
• sequentially transmitting each of the two or more network packets over an output port of the network router according to the arbitration weight values.
