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:
tftthe TFT to be added

References NS_ASSERT, and NS_LOG_FUNCTION.

Referenced by ns3::LteUeRrc::SetupRadioBearer().

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

classify an IP packet

Parameters:
pthe 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.

void ns3::EpcTftClassifier::Delete ( uint32_t  id)

delete an existing TFT from the classifier

Parameters:
idthe identifier of the TFT to be deleted
