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 Scheduler

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.

Overrides:

duplicate in class Scheduler

qosEnque

protected void qosEnque(Packet p_,
                        SpecR rspec_)

Description copied from class: Scheduler

Subclasses must override this method to provide its own enqueuing scheme.

Overrides:

qosEnque in class Scheduler

qosDeque

protected Packet qosDeque()

Description copied from class: Scheduler

Subclasses must override this method to provide its own dequeuing scheme.

Overrides:

qosDeque in class Scheduler

setFlowspec

public int setFlowspec(int handle_,
                       long[] tos_,
                       long[] tosmask_,
                       SpecFlow fspec_)

Description copied from class: Scheduler

Adds/modifies the flowspec with the specified handle. If no flowspec exists for the handle, the flowspec is added. Otherwise, the flowspec replaces the original one. No admission control is performed in this method. A subclass may need to override this method to create its own data structure for the successfully installed flow.

Overrides:

setFlowspec in class Scheduler

Following copied from class: drcl.intserv.Scheduler

Returns:

the handle.

removeFlowspec

public SpecFlow removeFlowspec(int handle_)

Description copied from class: Scheduler

Removes a flowspec. A subclass may need to override this method to remove its own data structure for the installed flow.

Overrides:

removeFlowspec in class Scheduler

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 Scheduler
