Module Interface IOutputQueue

Package: inet.common.queue
File: src/inet/common/queue/IOutputQueue.ned

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.

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.
