In embodiments described herein, one or more stream classifications are incorporated into a plurality of flows within a network. These flows can have a number of characteristics associated with it, such as, but not limited to quality of service requirements that can dictate how the flow should be processed. A device associated with the flow can transmit a stream classification service (SCS) request. This SCS request can be received and processed to determine a scheduling behavior that should be adopted by various network device / nodes associated with the flow. The scheduling behavior can be transmitted to those network devices which can then modify the processing of the flow(s). In some cases, the network device can classify the packets associated with the flow(s) and prioritize them. In additional cases, the network device can generate one or more new queues that can be configured to best serve the requirements of the flow.

Packet switching operations in network devices are managed based on detection of excess rate traffic flows. A network device receives data units, determines the traffic flow to which the data units belong, and updates flow tracking information for the flow.

The network device can enable one or more excess rate policies for excess rate traffic flows. Such policies can include any number of features affecting how the device handles data units belonging to the flow, such as excess rate notification, differential discard, differential congestion notification, and reprioritization. Memory and other resource optimizations for such flow tracking and management are also described.
