public class DropTailPointopointNI

extends QueueNI

The class implements the point-to-point network interface and emulates the physical link propagation. It is fully specified by the bandwidth, MTU and propagation delay. As a network interface, only one packet can be transmitted at a time. However as an emulated link, multiple packets may be outstanding, the number of which dependes on the propagation delay, bandwidth and packet size.

Method Detail

process

protected void process(java.lang.Object data_,
                       Port inPort_)

Description copied from class: Component

The main callback method of a component. Being invoked when data arrives at a port of its.

Overrides:

process in class Component

Parameters:

data_ - the arrival data.

inPort_ - the port where the data arrives.

duplicate

public void duplicate(java.lang.Object source_)

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 QueueNI

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 NI

isReady

public boolean isReady()

Returns true if the interface is ready to transmit more packets.

Specified by:

isReady in class NI

info

public java.lang.String info()

Description copied from class: Component

Returns information regarding this component. Subclasses should override this method to provide useful information at run time.

Overrides:

info in class QueueNI

setCapacity

public void setCapacity(int capacity_)

Sets the capacity of the queue.

Specified by:

setCapacity in class QueueNI

getCapacity

public int getCapacity()

Returns the capacity of the queue.

Specified by:
