IPacketShaper¶

module interface IPacketShaper

Interface for packet shaper modules. A packet shaper connects one input to one output. It operates in passive mode both on its input and its output. These modules may delay and reorder packets but they never modify or drop packets.

Implemented by¶

Name	Type	Description
AsynchronousShaper	compound module	Implements an asynchronous shaper. The queue sorts packets based on the transmission eligibility time (EligibilityTimeTag) attached to each packet. The gate prevents packets from being transmitted earlier than the attached transmission eligibility time.
CreditBasedShaper	compound module	Implements a credit-based shaper using a gate submodule to manage the number of credits.
PacketShaper	compound module	Combines a packet queue and a packet gate into a packet shaper module. The queue stores the packets sorted according to its ordering and the gate decides when the first packet can be pulled from the queue.
PriorityShaper	compound module	Combines a classifier, a scheduler, and several traffic shapers into a single packet shaper. Packets are classified into one of the traffic shapers, and the scheduler prioritizes among them.
TimeAwareShaper	compound module	Implements a time-aware shaper using a gate submodule that opens and closes according to a time-based schedule.

Extends¶

Name	Type	Description
IPassivePacketSink	module interface	Interface for passive packet sink modules. A passive packet sink, also called a consumer, has one input that must be connected to an active packet source module. The connected active packet source is expected to push packets into the passive packet sink over time.
IActivePacketSource	module interface	Interface for active packet source modules. An active packet source, also called a producer, has one output that must be connected to a passive packet sink module. The active packet source is expected to push packets into the connected passive packet sink over time.
