Abstract

In one exemplary aspect, a method of managing computer network traffic flow quality of service includes the step of configuring a configurable network device to provide a specified quality of service to a data packet with a specified quality of service configuration based on a quality of service classification port number in a data packet header of the data packet. At the source node, a data packet is generated. At the source node, replacing the destination port number in the data packet header with a quality of service classification port number. At the source node, the destination port number is included in an options field of the data packet's header. The data packet is communicated to the configurable network device. At the destination node, receiving the data packet, replacing the quality of service classification port number with the original destination port number, and forwarding the packet to a destination process.
