ABSTRACT:
In one embodiment, an intermediate network device includes a communication facility configured to receive a reservation request message that includes a flow spec object. The flow spec object specifies one or more flow parameters that describe a given traffic flow that desires to pass through the intermediate network device. A flow is configured to compare the one or more flow parameters specified in the flow spec object to one or more constants stored in a memory, to determine a type of traffic of the given traffic flow. The flow analyzer determines the type of traffic independent of any differentiated services codepoint (DSCP) values in packets of the given traffic flow. A traffic scheduler is configured to assign the given traffic flow to a particular per hop behavior (PHB) based on the determined type of traffic for the given traffic flow.
