PacketMeterBase¶

simple module PacketMeterBase

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.

Inheritance diagram¶

Known subclasses¶

Name	Type	Description
EligibilityTimeMeter	simple module	A packet meter which measures the packet flow that is passing through and optionally attaches an EligibilityTimeTag to the packets. The tag contains the calculated simulation time when the packet becomes eligible for transmission according to the asynchronous shaper algorithm.
ExponentialRateMeter	simple module	Attaches a RateTag to each packet specifying the data rate and packet rate of the received stream of packets. The algorithm takes older packets into account with an exponentially decreasing weight.
MultiTokenBucketMeter	simple module	Labels packets according to the first token bucket that contains the required number of tokens. If no such token bucket is found then the default label is attached to the packet.
SlidingWindowRateMeter	simple module	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.
TokenBucketMeter	simple module	Labels each packet if the token bucket contains enough tokens for the packet that is passing through. The amount of required tokens is equal to the packet length in bits and is subtracted from the number of stored tokens. New tokens are generated with the provided constant rate and they may also be added by other modules.

Extends¶

Name	Type	Description
PacketFlowBase	simple module	Base module for various packet flow modules. A packet flow module passes or streams all pushed or pulled packets after processing them from its input to its output.

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

Signals¶

Name	Type	Unit	Description

Statistics¶

Name	Title	Source	Record	Unit	Interpolation Mode	Description
flowIncomingDataRate	flow specific incoming data rate	throughput(demuxFlow(merge(packetPushedIn, packetPulledIn)))	vector	bps	linear	the statistical value is the flow specific data rate of the incoming packets
flowIncomingPacketLengths	flow specific incoming packet lengths	packetLength(demuxFlow(merge(packetPushedIn, packetPulledIn)))	sum,histogram,vector	b	none	the statistical value is the flow specific length of the incoming packet
flowOutgoingDataRate	flow specific outgoing data rate	throughput(demuxFlow(merge(packetPushedOut, packetPulledOut)))	vector	bps	linear	the statistical value is the flow specific data rate of the outgoing packets
flowOutgoingPacketLengths	flow specific outgoing packet lengths	packetLength(demuxFlow(merge(packetPushedOut, packetPulledOut)))	sum,histogram,vector	b	none	the statistical value is the flow specific length of the outgoing packet
incomingDataRate	incoming data rate	throughput(merge(packetPushedIn, packetPulledIn))	vector	bps	linear	the statistical value is the data rate of the incoming packets
incomingPacketLengths	incoming packet lengths	packetLength(merge(packetPushedIn, packetPulledIn))	sum,histogram,vector	b	none	the statistical value is the length of the incoming packet
incomingPackets	incoming packets	merge(packetPushedIn, packetPulledIn)	count	pk		the statistical value is the incoming packet
outgoingDataRate	outgoing data rate	throughput(merge(packetPushedOut, packetPulledOut))	vector	bps	linear	the statistical value is the data rate of the outgoing packets
outgoingPacketLengths	outgoing packet lengths	packetLength(merge(packetPushedOut, packetPulledOut))	sum,histogram,vector	b	none	the statistical value is the length of the outgoing packet
outgoingPackets	outgoing packets	merge(packetPushedOut, packetPulledOut)	count	pk		the statistical value is the outgoing packet
