PacketShaper

compound module

This 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.

Known subclasses

Name	Type	Description
AsynchronousShaper	compound module	This module implements an asynchronous shaper. The queue sorts packets based on the transmission eligibility time (EligibilityTimeTag) attached to each packet. The gate prevents packets to be transmitter earlier than the attached transmission eligibility time.
CreditBasedShaper	compound module	This module implements a credit based shaper using a gate submodule to manage the number of credits.
TimeAwareShaper	compound module	This module implements a time-aware shaper using a gate submodule that opens and closes according to a time-based schedule.
