BF2S Forums When will be the day of world wide servers?

,

yeah common you wankers.

You laugh now, but one day, a game like that will be a real thing.

Its a cool idea, and a cool dream.

At this time it is physically impossible to acheive a ping of 20-30ms especially in the worst case scenario where a player is located on the opposite side of the globe from the server. The limiting factor is the speed of light (c). For example, given that the equatorial circumference of the Earth is 40,075 km and c = 299,792 km/s, the theoretical shortest amount of time for a piece of information to travel half the globe along the surface is 0.066838 s (ping=67). Double that for the signal to be returned to the originating source (ping=134). Bear in mind that does not take into account other factors. The actual propagation delay is going to be significantly longer due to the fact that the speed of light is slower by about 30% in an optical fiber (ping =95 one way and 190ms round trip) Also the cable will not be directly connected from server to source and will have to repeated many times to prevent signal degradation. Typical single-mode systems can sustain transmission distances of 80 to 140 km (50 to 87 miles) between regenerations of the signal. 40075km/140km = 286 repeaters best case. Each repeater will add to the ping.

two words...flux capacitor

Then we will need 1.21 GigaWatt power supplies

No problem.  Everyone log in at exactly 10:04 PM Saturday.  Lightning should strike the clock generating 1.21 gigawatts and the flux capacitors will work!  I am gonna be pissed if my ping isn't under 100.
