ContentBasedScheduler¶

simple module ContentBasedScheduler

Connects one packet collector to multiple packet providers. It can be pulled for packets by the connected packet collector. When this happens, the scheduler pulls a packet from one of its packet providers based on the configured packet filters. The first matching expression determines the index of the input gate.

Extends¶

Name	Type	Description
PacketSchedulerBase	simple module	Base module for various packet scheduler modules. Derived modules must implement a single packet scheduler function which determines the index of the input gate for the pulled packet.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“scheduled %p pk (%l)”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
reverseOrder	bool	false
defaultGateIndex	int	0	Default gate index if no matching labels are found
packetFilters	object		Array of packet filter expressions

Properties¶

Name	Value	Description
class	ContentBasedScheduler
display	i=block/join

Gates¶

Name	Direction	Size	Description
in [ ]	input
out	output

Signals¶

Name	Type	Unit	Description
packetPulled	inet::Packet

Statistics¶

Name	Title	Source	Record	Unit	Interpolation Mode	Description
dataRate	data rate	throughput(packetPulled)	vector	bps	linear	the statistical value is the data rate of the scheduled packets
packetLengths	packet lengths	packetLength(packetPulled)	sum,histogram,vector	b	none	the statistical value is the length of the scheduled packet
packets	packets	packetPulled	count	pk		the statistical value is the scheduled packet
