Abstract
Methods, apparatuses and systems directed to the coordinated classification of network traffic. In one implementation, the present invention enables a coordinated network environment for traffic classification where an upstream network device classifies a data flow and adds traffic class information to at least one packet in the data flow. Downstream network devices in the communications path to the destination host can use the traffic class information in the modified packet, bypassing at least some of the local traffic classification operations and thereby reducing CPU utilization. In one implementation, the last downstream network device strips the traffic classification information from the modified packet before it is forwarded to the destination host. Embodiments of the invention reduce or eliminate redundant network traffic classification operations performed by a plurality of network devices in a communications path.
