Abstract
Packet metering systems and methods optimize utilization of yellow or excess tokens. The packet metering method includes receiving a packet of size B in an interval; and marking a color of the packet as green for committed, yellow for excess, or red for discard, based on the size B, a current committed token bucket for the interval, a current excess token bucket, and an overflow counter used to preserve unused yellow tokens from previous intervals while preserving Excess Information Rate (EIR) and Excess Burst Size (EBS) for the interval.
