Member Function Documentation

◆ Add()

uint8_t ns3::EpcTft::Add ( PacketFilter  f)

add a PacketFilter to the Traffic Flow Template

Parameters
fthe 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.
