public class TrafficShaperComponent

extends TrafficComponent

This component is the base class for regulating incoming packets and outputing the packets according to the associated traffic model.

A TrafficShaperComponent expects input data in Packet and outputs either the incoming packet or an enclosing packet that encapsulates the incoming packet.

A TrafficShaperComponent holds a TrafficShaper object that does the real job. One may plug in a different TrafficShaper object to create a different traffic shaper component.

Method Detail

reset

public void reset()

Description copied from class: Component

Resets the component for being used anew. All the internal variables must be set to the initial state. All the ports and child components are reset as well.

Overrides:

reset in class Component

Description copied from class: Component

Duplicates the content of source_, including ID, name, child components and connections among them, to this component. Subclasses need to override this method to copy its own variables.

Specified by:

duplicate in interface ObjectDuplicable

Overrides:

duplicate in class TrafficComponent

info

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

Overrides:

info in class TrafficComponent

Description copied from class: TrafficComponent

Returns the associated traffic model.

Specified by:

getTrafficModel in class TrafficComponent

setTrafficModel

public void setTrafficModel(TrafficModel traffic_)

Description copied from class: TrafficComponent

Sets the associated traffic model.

Specified by:

setTrafficModel in class TrafficComponent

setBufferSize

public void setBufferSize(int size_)

Sets the (maximum) buffer size of this traffic shaper (byte).

getBufferSize

public int getBufferSize()

Returns the (maximum) buffer size of this traffic shaper (byte).
