C++ definition

Reads the DSCP (lower six bits of ToS/TrafficClass) from the received datagram, and forwards the datagram to the corresponding output gate.

DSCPs are enumerated in the dscps parameter, first value is for out[0], second for out[1], etc. If the packet has no DSCP, or its value is not enumerated in the dscps parameter, it will be forwarded via the defaultOut gate.

Inheritance diagram

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

Used in compound modules

Name	Type	Description
DiffservQueue	compound module	This is an example queue that can be used in interfaces of DS core and edge nodes to support the AFxy (RFC 2597) and EF (RFC 3246) PHBs.
DiffservTrafficConditioner	compound module	TODO documentation
DSQueue1	compound module	Diffserv Queue used in Experiment 1.1 - 1.6 and 5.1.
DSQueue2	compound module	Diffserv Queue used in Experiment 2.1 - 2.4.
TrafficConditioner	compound module	TODO documentation

Extends

Name	Type	Description
PacketClassifierBase	simple module	Base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"classified %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
dscps	string	""	Space-separated dscp values of the gates, both names (e.g. AF11, EF) and numbers (0x0A,0b101110) can be used

Properties

Name	Value	Description
class	BehaviorAggregateClassifier
display	i=block/classifier

Gates

Name	Direction	Size	Description
in	input
out [ ]	output
defaultOut	output

Signals

Name	Type	Unit	Description
pkClass	long

Statistics
