public class traffic_TokenBucket

extends TrafficModel

implements TrafficPeriodic

This class describes the token bucket traffic model. It is defined by the following parameters:

Bucket Size

The size of the token bucket (byte).

Initial Bucket Size

The number of tokens that are available in the bucket initially (byte).

Token Generation Rate

Rate of tokens being generated and filled in the bucket (bps).

Output Rate

The rate of outputing packets out of the bucket (bps).

Maximum Transmit Unit (MTU)

The maximum size of a packet (byte).
