getLossRate

Field Detail

bytes

protected final AtomicLong bytes

The total number of bytes.

packets

protected final AtomicLong packets

The total number of RTP packets. This excludes RTCP packets, because the value is used to calculate the number of lost RTP packets.

bytesRetransmitted

protected final AtomicLong bytesRetransmitted

Number of bytes retransmitted.

bytesNotRetransmitted

protected final AtomicLong bytesNotRetransmitted

Number of bytes for packets which were requested and found in the cache, but were intentionally not retransmitted.

packetsRetransmitted

protected final AtomicLong packetsRetransmitted

Number of packets retransmitted.

packetsNotRetransmitted

protected final AtomicLong packetsNotRetransmitted

Number of packets which were requested and found in the cache, but were intentionally not retransmitted.

packetsMissingFromCache

protected final AtomicLong packetsMissingFromCache

The number of packets for which retransmission was requested, but they were missing from the cache.

bitrate

protected org.jitsi.utils.stats.RateStatistics bitrate

The bitrate.

packetRate

protected org.jitsi.utils.stats.RateStatistics packetRate

The packet rate.

Method Detail

getSSRC

public long getSSRC()

Specified by:

getSSRC in interface TrackStats

Returns:

the SSRC associated with this TrackStats.

packetProcessed

protected void packetProcessed(int length,
                               long now,
                               boolean rtp)

Notifies this instance that a packet with a given length was processed (i.e. sent or received).

Parameters:

length - the length of the packet.

now - the time at which the packet was processed (passed in order to avoid calling System.currentTimeMillis()).

rtp - whether the packet is an RTP or RTCP packet.

getJitter

public double getJitter()

Specified by:

getJitter in interface TrackStats

Returns:

the jitter in milliseconds.

getRtt

public long getRtt()

Specified by:

getRtt in interface TrackStats

Returns:

the round trip time in milliseconds.

getBytes

public long getBytes()

Specified by:

getBytes in interface TrackStats

Returns:

the total number of bytes.

getPackets

public long getPackets()

Specified by:

getPackets in interface TrackStats

Returns:

the total number of packets.

getBitrate

public long getBitrate()

Specified by:

getBitrate in interface TrackStats

Returns:

the current bitrate in bits per second.

getPacketRate

public long getPacketRate()

Specified by:

getPacketRate in interface TrackStats

Returns:

the current packet rate in packets per second.

getCurrentBytes

public long getCurrentBytes()

Specified by:

getCurrentBytes in interface TrackStats

Returns:

the number of bytes in the last interval.

getCurrentPackets

public long getCurrentPackets()

Specified by:

getCurrentPackets in interface TrackStats

Returns:

the number of packets in the last interval.

getInterval

public long getInterval()

Specified by:

the interval length in milliseconds over which TrackStats.getCurrentBytes() and TrackStats.getCurrentPackets() operate.

setJitter

protected void setJitter(double jitter)

Sets the last jitter that was sent/received.

Parameters:

jitter - the new value to set on this instance as the last sent/received jitter (in milliseconds).

setRtt

protected void setRtt(long rtt)

Sets rtt to a specific value in milliseconds.

getBytesRetransmitted

public long getBytesRetransmitted()

Gets the number of bytes retransmitted.

Specified by:

getBytesRetransmitted in interface TrackStats

Gets the number of bytes for packets which were requested and found in the cache, but were intentionally not retransmitted.

Specified by:

getBytesNotRetransmitted in interface TrackStats

Returns:

the number of bytes for packets which were requested and found in the cache, but were intentionally not retransmitted.

getPacketsRetransmitted

public long getPacketsRetransmitted()

Gets the number of packets retransmitted.

Specified by:

getPacketsRetransmitted in interface TrackStats

Returns:

the number of packets retransmitted.

getPacketsNotRetransmitted

public long getPacketsNotRetransmitted()

Gets the number of packets which were requested and found in the cache, but were intentionally not retransmitted.

Specified by:

getPacketsNotRetransmitted in interface TrackStats

Returns:

the number of packets which were requested and found in the cache, but were intentionally not retransmitted.

getPacketsMissingFromCache

public long getPacketsMissingFromCache()

Gets the number of packets for which retransmission was requested, but they were missing from the cache.

Specified by:

getPacketsMissingFromCache in interface TrackStats

Returns:

the number of packets for which retransmission was requested, but they were missing from the cache.

rtpPacketRetransmitted

protected void rtpPacketRetransmitted(long length)

Notifies this instance that an RTP packet with a given length was not retransmitted (that is, the remote endpoint requested it, and it was found in the local cache, but it was not retransmitted).

Parameters:

length - the length in bytes of the packet.

rtpPacketNotRetransmitted

protected void rtpPacketNotRetransmitted(long length)

Notifies this instance that an RTP packet with a given length was retransmitted.

Parameters:

length - the length in bytes of the packet.
