Abstract
A network infrastructure device includes a receiver operable to receive packets when operably connected to a communication network; and a processor cooperatively operable with the transceiver. The processor can receive a packet on an interface corresponding to the transceiver. Also, the processor can map the packet to one of several queues and to one of several classifications, based on an indication of priority of handling in a header in the packet and/or an indication of priority in a configuration of the interface. The processor also checks for congestion in the queues with respect to the classification of the packet, and checks for congestion in the one queue with respect to the one classification. The processor queues the packet if there is no congestion, otherwise the processor drops the packet.
