bytesSent

Total number of RTP packets sent for this SSRC.

Description

Non-negative integer

Total number of RTP packets sent for this SSRC. This includes retransmissions. Calculated as defined in RFC3550 section 6.4.1.

Interpreting Values

  • This is a cumulative counter - it only increases over the lifetime of the connection
  • The raw value is primarily useful for computing send bitrate. Use bytesSent(bits/s) for real-time analysis
  • A flattening of the cumulative curve means sending has stopped or dramatically slowed
