DSCPMarker

simple module

This module sets the DSCP field (lower six bit of Tos/TrafficClass) of IP datagrams to the value specified by the dscps parameter.

The dscps parameter is a space separated list of DSCP values. Packets arrived at gate in[i] are marked with the ith value. If there are fewer dscp values given than input gates, then the last one is repeated.

Parameters

Name	Type	Default value	Description
dscps	string		space separated list if dscp values; both names (e.g. AF11, EF) and numbers (0x0A,0b101110) can be used

Properties

Name	Value	Description
display	i=block/star

Gates

Name	Direction	Size	Description
in [ ]	input
out	output

Signals

Name	Type	Unit
markPk	cPacket

Statistics

Name	Title	Source	Record	Unit	Interpolation Mode
markPk	packets marked	markPk	count, sum(packetBytes), vector(packetBytes)		none
