1. A method for marking an excessive bandwidth packet in a packet switching network, the method comprising the steps of:

  • a. accumulating a count of bytes of data arriving at an access node per interval;

    b. receiving a packet with a number of bytes of data;

    c. comparing the accumulated count of bytes of data arriving at the access node per interval with a predetermined threshold;

    d. if the accumulated count is less than the threshold, incrementing the count in the accumulator by a constant plus the number of bytes of data in the received packet;

    e. if the accumulated count is greater than the threshold, marking the received packet; and

    f. subsequent to step d or e, passing the unmarked or marked packet along in the access node.
