<PRE>According to Charles Dupont:
><i> How much band width do you think you will need for your server cluster
</I>><i> when your service is up and running?
</I>
About an OC12 (655Mbits) per user.
Ooops, sorry, was thinking about the pan-sensorial version with direct
neural feed for complete immersion :)
By design, we want to restrict the bandwidth to at most what a user with
a 57.6K modem can 'swallow' realistically, which means a bandwidth
of compressed data that tops at around 4Kbytes/s (or 32Kbits/s).
Multiply by the number of simultaneous people a cluster has to serve,
which we aim at around 3000-3500 players, and you get a little under
an OC4 per cluster (about 110Mbits) for theoretical peak usage.
