Packet Loss Rate

Packet Loss Rate is a measure of network congestion, expressed as a percentage of packets lost with respect to packets sent.

Constant loss refers to the condition where a channel is losing packets at a constant rate. In such cases, the SRT overhead is lower bound limited, such that:

Minimum Bandwidth Overhead = 1.65 * Packet Loss Rate

Burst loss refers to the condition where a channel is losing multiple consecutive packets, up to the equivalent of the contents of the SRT latency buffer. In such cases, the SRT overhead is lower bound limited, such that:

Minimum Bandwidth Overhead = 100 ÷ RTT Multiplier

Burst losses that last longer than the SRT Latency will result in stream artifacts. SRT Latency should always be set to a value above your worst case burst loss period.
