RelayInterfaceLearner¶

simple module RelayInterfaceLearner

Extracts the source MAC address of the packet passing through and stores the mapping from this MAC address to the incoming network interface in the MAC address table (forwarding information database).

Usage diagram¶

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
InterfaceRelayLayer	compound module	Combines the interface MAC address learning from incoming packets with the outgoing interface selection for outgoing packets into a single layer.

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	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
macTableModule	string		Relative module path of MAC table
interfaceTableModule	string		Relative module path of the interface table

Properties¶

Name	Value	Description
class	RelayInterfaceLearner
display	i=block/blackboard

Gates¶

Name	Direction	Size	Description
in	input

Signals¶

Name	Type	Unit	Description
packetPulledIn	inet::Packet
packetPulledOut	inet::Packet
packetPushedIn	inet::Packet
packetPushedOut	inet::Packet

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
