Prototype for output queues. Concrete queues can implement drop-tail, RED etc. policy.

The implementation of IOutputQueue can be either a simple module whose C++ class implements (i.e. subclass from) IPassiveQueue, or a compound module whose out gate is connected to a simple module implementing the IPassiveQueue interface. The IPassiveQueue component should send a packet whenever a module asks for one by calling the requestPacket() method.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
DiffservQueue	compound module	This is an example queue, that can be used in interfaces of DS core and edge nodes to support the AFxy (RFC 2597) and EF (RFC 3246) PHBs.
DropTailQueue	simple module	Drop-tail queue, to be used in network interfaces. Conforms to the IOutputQueue interface.
EtherQoSQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and can be parametrized with an IOutputQueue for serving the other frames.

Used in compound modules

Name	Type	Description
EtherQoSQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and can be parametrized with an IOutputQueue for serving the other frames.
IdealWirelessNic	compound module	Highly abstracted wireless NIC that consists of a unit disk radio and a trivial MAC protocol. It offers simplicity for scenarios where Layer 1 and 2 effects can be completely ignored, for example testing the basic functionality of a wireless ad-hoc routing protocol.
Ieee802154UWBIRNic	compound module	(no description)
PPPInterface	compound module	PPP interface. Complements the PPP module with an output queue for QoS and RED support.
