It varies by the map and such, but in the middle of a round on cp_follower, our full 30man server is using ~650KB/sec upstream and ~100KB/sec download. I've seen the upstream bandwidth usage spike to 800KB+ occasionally.

This is old as :crab:

Basically for internet connections (bits/second):

    128k uplink = 4 players (2 players for srcds)
    256k uplink = 7 players (4 players for srcds)
    320k uplink = 9 players (6 players for srcds)
    512k uplink = 14 players (9 players for srcds)
    768k uplink = 21 players (14 players for srcds)
    1024k uplink = 28 player (19 players for srcds - note 16 players is max for HL2DM)
    1140k uplink = 32 players (max for HLDS) (21 players for CS:S)
    1708k uplink = 32 players for CS:S (max)

Your particular optimal setting may vary depending on your connection. Local players on LAN are not included in this count.

A good rule for HLDS is 35.6Kbits per player .

A good rule for SRCDS (Source Games) is *53.4KBits per player (about 1.5x more than HLDM).
*6,675KB/s per player wtf ? Could be possible if idle alone in server
Certain maps and MODs may take more uplink bandwidth.

You have not even mention what game you are going host.
Of course you can host 19 player server. No one can't deny you for that.
But don't expect it's "lagless" wth 1Mbps upload.


Cs:s taking 15KB/s ~ 25KB/s by one player, x 19 players
around = 285KB/s ~ 475KB/s
in my opinion
