Net quality latency settings

Post by Digital1955 »

Can you please tell me how many ms of latency each of the the "Net Quality" settings introduce? I assume Optimal = 0ms and Very slow is around maybe 100 ms? I realize that VBAN was spec'd for LAN usage, but I would love to see a dynamic buffer employed such that it could be more optimized for WAN usage.

"Optimal" mode introduces a minimal buffering (< 15ms) to let you get the best latency on your receptor device (can be < 50ms on WIFI link).
"Very slow" introduces around 100ms buffering.

Note outgoing streams must keep "Optimal" settings (if it does not work in this mode it means the UDP stack is busy, so means the Ethernet stack is busy, no way to make it work better).

While receptor can be set in "Slower" mode if the network connection is bad...
Our test are always made in Optimal Network mode(even on WIFI connection) but we recommend the FAST mode on WIFI link to get a better stream stability.
