Member Function Documentation

void ns3::EpcTftClassifier::Add	(	Ptr< EpcTft >	tft,
		uint32_t	id
	)

add a TFT to the Classifier

Parameters

tft	the TFT to be added
id	the ID of the bearer which will be classified by specified TFT classifier

Here is the caller graph for this function:

uint32_t ns3::EpcTftClassifier::Classify	(	Ptr< Packet >	p,
		EpcTft::Direction	direction
	)

classify an IP packet

Parameters

p	the IP packet. It is assumed that the outmost header is an IPv4 header.
direction	the EPC TFT direction (can be downlink, uplink or bi-directional)

Returns

the identifier (>0) of the first TFT that matches with the IP packet; 0 if no TFT matched.
