PSX Clients getting out of sync
« on: Sun, 25 Oct 2020 09:20 »
I sometimes get my PSX clients going out of sync with the PSX Server. To rectify, I have to disconnect and connect the client's networking in PSX which syncs it back up.

It manifests at the start of the flight, with one client's IRS fully aligned, and the other stuck on 0 min (see photo https://www.dropbox.com/s/2ee4rtjy0n7pbbl/unnamed%20%281%29.jpg?dl=0).

Sometimes the FD disappears too (see photo https://www.dropbox.com/s/pca32imasw2pcuw/unnamed.jpg?dl=0)

Maybe I'm having networking issues (I have a 1 Gbps network between everything). So I did a speedtest between the PSX Server and PSX client PCs and got:

client A to PSX server:
Code: [Select]
TCP Up:   450.00 Mbps (Ave: 450.00)     UDP Up:   483.05 Mbps (Ave: 459.88), Loss: 2.5%
TCP Down: 504.66 Mbps (Ave: 504.66)     UDP Down: 472.45 Mbps (Ave: 435.82), Loss: 4.0%
Round-trip time: 0.8 ms

client B to PSX server:

Code: [Select]
TCP Up:   209.83 Mbps (Ave: 209.83)     UDP Up:   330.84 Mbps (Ave: 427.10), Loss: 34.4%
TCP Down: 525.38 Mbps (Ave: 525.38)     UDP Down: 543.80 Mbps (Ave: 511.02), Loss: 0.2%
Round-trip time: 0.6 ms

Bowing to your collective expert knowledge  ;D

When the FD disappears on just one side, it may be a normal effect due to system logic (onside FD switch OFF, or selected CMD on same onside FCC source).

You can't reasonably test network synchronity by comparing the captain's with the F/O's instruments. You need to compare exactly the same instruments on each network instance. E.g. pan the F/O's layout so that you see the captain's instruments on the F/O's layout (just for the test).
