Server bandwith needed (DCS 1.2.6)

[VTJS17_Fire]

Hi,

 

long time ago, there was the information here on the forums, that the host should have 256kbit/s per player - or 1Mbit/s for 4 players.

 

Some weeks ago, I hosted a server for 10 clients ... with a 2Mbit cable connection. My own computer was the server.

 

So:

+ Is 256kbit/s for each client still effective?

+ What will happen, if the bandwith for each client is to low?

+ Do you have experience, how many clients I could server with 2mbit upload?

 

 

Note:

Clients are only from Germany (1 from Austria), all with a ping between 40 and 80ms.

 

 

Thanks in advance,

regards Fire

With some of my smaller AI missions I've seen each client drawing 500-740kb/s so the days of 4 per mb are over my friend. 1 mb/s per person (when you factor in voice coms as well) is the more current standard.

 

Insufficient bandwidth will lead to increase in ping / lag not to mention warping and loss of synchronicity in the server between the server and the clients.

 

Sorry to be the bearer of bad news.

1 mb/s per person (when you factor in voice coms as well) is the more current standard.

 

But if this is true, how could I run a server with 10 clients and pings between 40ms and 80ms (depends on bandwith/ fastpath on the clients end) - with my 2Mbit/s upload? :huh:

 

Where can I read, how many upstream is current used?

Where can I read, how many upstream is current used?

For example in Windows Task Manager, tab "Networking". Or you can install some monitoring utility (i.e. NetWorx and many similar tools), this can monitor bandwidth usage in background and generate excel/word/html-reports.

 

But be aware that this tools usually calculate an average value (i.e. traffic per second, as TaskManager). So you might see network traffic never reached limit of your connection speed, but within that averaging interval it might have happened.

By your calculations then I should be able to host a server with over 70 people... when I can't actually host for more than 15 before lag and warping kills the experience.

 

So now we go down to AI units involved... the more AI involved, the more tax on the connection.

 

Were you guys flying a large mission with 100s of AI- or just flying head to head?

 

That is going to be the difference.

What's your bandwidth estimate without voice comms, per person?

[Pman]

on the VA server its generally about 350-500kbps per player and thats with zero AI

 

If you have an AI heavy mission like ENO then I can easily expect that to double, at least.

From my testing 2Mbits with all the bells and whistles is a bit low,I found out that a simple server is best. I recomend that you have atleast 10Mbits(upload speed) for an advanced server,but the internet is just one part you have the hardware and software also. Just test the server and thru testing you will know your server limits. Recommended hardware: I7 series and FX series cpu's,8 gigs ram,Directx 10 or 11 gpu cards. Software: 64bit operating systems Win 7 or Win 8.
