1. A method for dropping lower priority packets for transmission over a communication medium, comprising the steps of:

  • receiving one or more packets to be transferred to one or more data providers, each packet having a priority;

    based on said priority, storing each of the packets in one or more priority queues in a fixed shared memory space in such a way as to maintain the order in which the packets were received in each of said priority queues;

    monitoring the number of packets in each of said priority queues and signaling an interrupt when a packet threshold is exceeded in said one or more priority queues; and

    dropping lower priority packets in said fixed shared memory space based on said order received.
