// Simple token bucket meter.

// IP packets are classified according to two parameters,
// Committed Information Rate (cir), Committed Burst Size (cbs),
// to be either green or red.
//
// Green traffic is guaranteed to be under (in bits)
// <pre>
//     cir * (t1 - t0) + 8 * cbs
// </pre>
// in every [t0, t1] interval.
//
// When operating in color-aware mode, the meter does not classify
// a packet to be green if it was marked with a higher color
// by a previous meter.
