Latency can vary from tens of milli-seconds milliseconds to several seconds.
Zixi protocol can be beneficial in as little as one frame (30ms), while increasing the latency will provide more robustness for the error-recovery.
...
For getting sufficient error-recovery we are recommending to set the Latency latency at least 3 times larger than the RTT (i.e Latency >= 3* RTT).
Latency can be set to any value, we can propose recommend two common modes:
- Interactive mode – 500ms
- Non-interactive mode – 4000ms
Latency below 1500ms will add a an FEC overhead of up to 30%.
