Server 101

[Shifty_DSC]

OK I am the first to admit that I'm Mr. Server Admin newbie.

Anyway, I'm building a new box and CoD will currently be one of the primary games run. Is there any information available as to how much bandwidth up/down is recommended per client?

This box will run on it's own dedicated line but I have to pay (go figure) based on how fat I want the pipe. Looking for any input.

Great site btw, came here with one question and have completely smashed 5 cfg's toying with other things I read here lol.

I would recomend keeping the pipe uncapped - try an keep your server full all month and see what it uses.

It will depend on how many clients you have X maxrate.

You could possibly estimate what you will need but it all depends on how much the server is played in by how many people.

Tighten is correct. Multiply your sv_maxrate (the rate in Kilobytes/sec) you want to send each client. I find sv_maxrate 8000 to be good for RTCW (Same engine as CoD), so your mileage may vary.

do the following calculation:

(sv_maxrate) x (# of slots you want, sv_maxclients) x (8) = bits/sec.

I ran a 34 player RTCW server, sv_maxrate of 8000; which yields:
8000 x 34 x 8 = 2176000 (or just under 2.2 Megabits/sec). I verified this using MRTG on our router & switch ports.

If you only have a DS1 of bandwidth (1.5 Mbits or so), you can only support 24 players at one time; or else you'll hit the upper limit of your pipe.

- R208.

You may want to set the rate as well as cap until you get an idea so you don't get hit with a big bill. I'm not capping the bandwidth or rate on mine and with 40 people it peaked at 4.22 meg. The average is about 2.8 meg. I'm using cricket ( very similar to MRTG ) and it polls every 5 minutes. Resolution, you may want to check out cricket. Same thing as MRTG only better ;). It also does SNMP and you can see your processor usage, paging etc. It's pretty nice.

So if I follow this formula I am looking at roughly 4000GB/month trafic for a 20 player server? If not. What would I be looking at in monthly usage for a 20 player server?

If you are paying per-gig then I guess so? I am not sure if the formula is completely accurate though.

Also mrtg you get charged the average - not usage.
