availableOutgoingBitrate
candidate-pairoutgoingvoicevideo
The available bitrate for all outgoing media streams for this candidate pair.
Description
Real number
It is calculated by the underlying congestion control by combining the available bitrate for all the outgoing RTP streams using this candidate pair.
The bitrate measurement does not count the size of the IP or other transport layers like TCP or UDP. It is similar to the TIAS defined in RFC3890, i.e., it is measured in bits per second and the bitrate is calculated over a 1 second window. For candidate pairs in use, the estimate is normally no lower than the bitrate for the packets sent at lastPacketSentTimestamp, but might be higher.

Notes
- Only exists when the underlying congestion control calculated either a send-side bandwidth estimation, for example using mechanisms such as TWCC, or received a receive-side estimation via RTCP, for example the one described in REMB
- MUST NOT exist for candidate pairs that were never used for sending packets that were taken into account for bandwidth estimation or candidate pairs that have have been used previously but are not currently in use
