Member Function Documentation

uint8_t ns3::EpcTft::Add

(

PacketFilter

f

)

add a PacketFilter to the Traffic Flow Template

Parameters

f	the PacketFilter to be added

Returns

the id( 0 <= id < 16) of the newly added filter, if the addition was successful. Will fail if you try to add more than 15 filters. This is to be compliant with TS 24.008.

		uint8_t	typeOfService
	)

Parameters

direction
remoteAddress
