PacketMeterBase

Package: inet.queueing.base

PacketMeterBase

simple module

C++ definition

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

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the 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

the statistical value is the data rate of the outgoing packets

incomingDataRate incoming data rate throughput(merge(packetPushedIn, packetPulledIn)) vector bps linear

the statistical value is the data rate of the incoming packets

outgoingPacketLengths outgoing packet lengths packetLength(merge(packetPushedOut, packetPulledOut)) sum, histogram, vector b none

the statistical value is the length of the outgoing packet

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

incomingPacketLengths incoming packet lengths packetLength(merge(packetPushedIn, packetPulledIn)) sum, histogram, vector b none

the statistical value is the length of the incoming packet

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

incomingPackets incoming packets merge(packetPushedIn, packetPulledIn) count pk

the statistical value is the incoming packet

outgoingPackets outgoing packets merge(packetPushedOut, packetPulledOut) count pk

the statistical value is the outgoing packet
