Detailed Description

classifies IP packets accoding to Traffic Flow Templates (TFTs)

Note

this implementation works with IPv4 only.

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

Definition at line 49 of file epc-tft-classifier.cc.

References NS_ASSERT, and NS_LOG_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.

Returns

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