Bandwidth calculator for hosting
Bandwidth calculator for hosting
I created a small sheet to calculate number of pilots and spectactors a server can support, accordingly to its upload bandwidth available.
(No pretention here, I'm a noob in Excel)
EDIT: Updated to include UDP packet header size and specify values are in kilo bytes.
Just select your connection speed (warning: UPLOAD, not download!)(No pretention here, I'm a noob in Excel)

Re: Bandwidth calculator for hosting
Today we ran a server with everything set to unlimited. At peak 84 pilots and 4 Spectate! Users were connected. We run a 1000 Mbit server in a datacenter in Amsterdam. Pings were almost all below 100. Flying in large gaggles gives a bit of a FPS hit (around 30 FPS for me running everything on max settings). Users with the settings turned down reported less of a FPS drop and still very much playable framerates. Once the field spread, normal FPS for everybody. No glitches or freezes reported.

I think you missed the 8 byte header for UDP?BOD1 wrote: ↑Mon May 11, 2020 11:18 pmI created a small sheet to calculate number of pilots and spectactors a server can support, accordingly to its upload bandwidth available.

This is very helpful, thank you. For the avoidance of doubt, can you confirm the upload speed is mega/kiloBYTES per second not BITS?BOD1 wrote: ↑Mon May 11, 2020 11:18 pmI created a small sheet to calculate number of pilots and spectactors a server can support, accordingly to its upload bandwidth available.

Well connections are always specified in kilobits or megabits. I have never seen one specified in megabytes/sec
In any case, divide bits by 8 to get bytes.

Re: Bandwidth calculator for hosting
In my array, it's in KB per second(KiloBytes, 1 kilo = 1024 bytes), I thought KB would be more meaningful than bits for average users, internet browsers indicate download speeds in bytes.
@Oxo "I think you missed the 8 byte header for UDP?"
Probably, I used the value given by Uros for a single plane location (105 bytes), and I don't know how many packets are used to send it.
I don't take in account all overhead due to joining, chat, ...
File has been updated (see first post).

Re: Bandwidth calculator for hosting
ISP's usually communicate in Mb (Megabits) per second to their costumers. That looks nicer (more).
But most costumers often think in MB (MegaBytes) per second. And some even think they get MB while in reality they only get Mb...

BOD1 could you reload attachment? I can't download it - get info that is missing.

Thx BOD1
I have 50Mb/s upload (6.25MB/s) so I get all green spreadsheet
