ABSTRACT:
A network access device checks communication data flows coming into a network for specific authorization information. The quality of service class (QOS) with which a flow is retransmitted from the network access device through the network is determined by the result of the check. Each end device that transmits a flow to the network access device can first request authorization for the flow from a gate keeper and resource manager mechanism of the network. The mechanism returns specific authorization information which the end device includes in the flow before the flow is transmitted to the network access device. In one embodiment, only if an incoming flow is determined to have the specific authorization information will the network access device allow the flow to be retransmitted through the network with a particular quality of service (QOS) class.
