Method Detail

reset

public void reset()

Overrides:

reset in class TrafficShaper

info

public java.lang.String info(java.lang.String prefix_)

Description copied from class: TrafficShaper

Prints out the content of this traffic shaper instance. This class prints out the associated traffic model and the buffer. A subclass only needs to call super.info(prefix_) and then supply the content of the parameters defined in the subclass.

Overrides:

info in class TrafficShaper

Parameters:

prefix_ - prefix_ that should be prepended at each line.

adjust

protected double adjust(double now_,
                        int size_)

Description copied from class: TrafficShaper

Returns the time adjustment (relative to the current time now_) for outputing the packet. This is the main method a subclass must override to regulate the incoming packets. The current time passed to this method is maintained relatively to the time when this component starts.

Specified by:

adjust in class TrafficShaper

Parameters:

now_ - current time, relative to the start time of the shaper.

size_ - the packet size.

getTrafficModel

public TrafficModel getTrafficModel()

Description copied from class: TrafficShaper

Returns the associated traffic model.

Specified by:

getTrafficModel in class TrafficShaper

setTrafficModel

public void setTrafficModel(TrafficModel traffic_)

Description copied from class: TrafficShaper

Sets the associated traffic model.

Specified by:

setTrafficModel in class TrafficShaper

setOutputRate

public void setOutputRate(double rate_)

getOutputRate

public double getOutputRate()

setTokenGenRate

public void setTokenGenRate(int rate_)

getTokenGenRate

public int getTokenGenRate()

public int getBucketSize()

setInitBucketSize

public void setInitBucketSize(int size_)

getInitBucketSize

public int getInitBucketSize()

getMTU

public int getMTU()

setMTU

public void setMTU(int mtu_)

set

public void set(int bsize_,
                int initbsize_,
                int trate_,
                double outrate_,
