StreamFilter

simple module

Implements a packet filter using solely the stream name. The stream name must match the filter criteria in order for the packet to pass through the filter.

Inheritance diagram

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

Extends

Name	Type	Description
PacketFilterBase	simple module	Base module for various packet filter modules. Derived modules must implement a single packet matcher function which determines if a packet is to be passed through or filtered out.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"dropped %d/%p pk (%k/%l)"	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
backpressure	bool	false
mode	string	"both"
streamNameFilter	string	"*"	Filter expression for the stream name

Properties

Name	Value	Description
class	StreamFilter
display	i=block/downarrow

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit	Description
packetPushedIn	inet::Packet
packetPulledIn	inet::Packet
packetDropped	inet::Packet
packetPushedOut	inet::Packet
packetPulledOut	inet::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
flowDroppedDataRate	flow specific dropped data rate	throughput(demuxFlow(packetDropped))	vector	bps	linear	the statistical value is the flow specific data rate of the dropped packets
droppedPackets	dropped packets	packetDropped	count	pk		the statistical value is the dropped packet
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
outgoingDataRate	outgoing data rate	throughput(merge(packetPushedOut, packetPulledOut))	vector	bps	linear	the statistical value is the data rate of the outgoing packets
