SlidingWindowRateMeter¶

simple module SlidingWindowRateMeter

Attaches a RateTag to each packet specifying the data rate and packet rate of the received stream of packets. The algorithm takes packets into account only in the given time window.

Extends¶

Name	Type	Description
PacketMeterBase	simple module	Base module for various packet meter modules. Derived modules must implement a single `meterPacket()` function which meters the flow of and attaches the required tags.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“metered %p pk (%l)”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
timeWindow	double		Amount of time to look back from the current simulation time

Properties¶

Name	Value	Description
class	SlidingWindowRateMeter
display	i=block/star
