Simple Module TokenBucketMeter

Package: inet.networklayer.diffserv
File: src/inet/networklayer/diffserv/TokenBucketMeter.ned

C++ definition

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) cir * (t1 - t0) + 8 * cbs 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.
