Member Function Documentation

Time ns3::DelayJitterEstimation::GetLastDelay

(

void

)

const

Returns:

the updated delay.

Time ns3::DelayJitterEstimation::GetLastJitter

(

void

)

const

The jitter is calculated using the RFC 1889 (RTP) jitter definition.

Returns:

the updated jitter.

static void ns3::DelayJitterEstimation::PrepareTx

(

Ptr< const Packet >

packet

)

[static]

Parameters:

packet

the packet to send over a wire

This method should be invoked once on each packet to record within the packet the tx time which is used upon packet reception to calculate the delay and jitter. The tx time is stored in the packet as an ns3::Tag which means that it does not use any network resources and is not taken into account in transmission delay calculations.

void ns3::DelayJitterEstimation::RecordRx

(

Ptr< const Packet >

packet

)

Parameters:

packet

the packet received

Invoke this method to update the delay and jitter calculations After a call to this method, GetLastDelay and GetLastJitter will return an updated delay and jitter.
