Member Function Documentation

Add()

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.

Default()

Ptr< EpcTft > ns3::EpcTft::Default ( void  )

static

creates a TFT matching any traffic

Returns

a newly created TFT that will match any traffic
