N2003 hosting - max cars on a cable connection

by j[nospam]ca.. » Tue, 06 Jan 2004 07:54:02

        I seem to recall seeing somewhere a formula or some such thing
that let you figure out what the max numbers of cars you could host in
N2003 given upload/download speeds.  Does anyone know of such a
formula, or if not, how many cars can you host in N2003 given certain
upload speeds?   I suppose I could just let people keep joining till
it sucks ;-), but i'd rather know ahead of time what to expect.  I
check the readme, and did a cursory search of google and TLS, but
couldn't find what i was looking for.

thx in advance

Hi,

Extract from server.txt in the N2003 directory:

"For each client connecting to the server using TCP/IP, the server will use
at most about 21K bits per second of bandwidth.  You'll need to experiment
to see how many clients your connection is actually capable of supporting.
It's probably not worth trying to host more than 3 clients on a 56K modem
(and 3 will probably be dicey).  It's probably not worth trying to host more
than, say, 15 to 20 on a cable modem.  If you do try to push the envelope
(you wouldn't do that, would you?) here are some clues that you've gone too
far:

 1. The rate at which clients lose their connection to the server increases
significantly.
 2. The latency for many of the clients increases as new clients connect, or
their quality decreases.  You can monitor this using the Entries table on
the Race Weekend screen.  Clients should monitor their own connection using
the communications meters while on track (hitting Control-C while in car
will toggle the meters on/off).
 3. Clients report more "warping" as yet more clients connect."

Regs.

22k bandwidth per car I believe.

Cable connections are not all that great for hosting, at least with the ISPs
in my area. Most ISPs put a cap on your upload speed much lower than your
download cap. Usally the cap is 128k or 256k. so thats only 2 or 4 times
better than a 56k dail up for band width. At the recomended 21k per car
thats only 6 cars tops with 128k or 12 with a 25k cap. If you know you
upload cap divide it by 21 and then subtract 1 and thats most likely your
practical limit.(5 on a 128 cap or 11 on a 256 cap)
