Quick and dirty delay and jitter estimation, implementing the jitter algorithm originally from RFC 18...
void RecordRx(Ptr< const Packet > packet)
static void PrepareTx(Ptr< const Packet > packet)
uint64_t GetLastJitter(void) const
The jitter is calculated using the RFC 1889 (RTP) jitter definition.
Time m_transit
Relative transit time for the previous packet.
Time m_jitter
Jitter estimation.
Simulation virtual time values and global simulation resolution.
