How Gaming Servers Work • The moment When you input information from your computer it bounces. • Here is a technical example: Tracing route to 220.127.116.11 over a maximum of 30 hops 1 10 ms 10 ms 10 ms 10.116.182.1 2 17 ms 13 ms 34 ms boi-edge-01.inet.qwest.net [18.104.22.168] 3 14 ms 17 ms 24 ms boi-core-02.tamerica.net [22.214.171.124] 4 132 ms 130 ms 127 ms sea-core-03.tamerica.net [126.96.36.199] 5 114 ms 111 ms 120 ms unknown.Level3.net [188.8.131.52] 6 110 ms 104 ms 102 ms ge-4-0-1.mp1.Seattle1.level3.net [184.108.40.206] 7 135 ms 131 ms 142 ms so-3-0-0.mp2.LosAngeles1.Level3.net [220.127.116.11] 8 152 ms 171 ms 168 ms gige9-0.hsipaccess1.LosAngeles1.Level3.net [64.1 59.1.209] 9 148 ms 153 ms 206 ms unknown.Level3.net [18.104.22.168] 10 145 ms 148 ms 144 ms cor01-vl-127.ca-pasadena0.ne.earthlink.net [22.214.171.124] 11 175 ms 177 ms 178 ms dir01-vl-264.ca-pasadena0.ne.earthlink.net [126.96.36.199] 12 137 ms 143 ms 135 ms 188.8.131.52 Trace complete.
How Gaming Servers Work • The route that the data packet takes would be from a house in Southern Idaho to several places across the country until it reaches the game server in Pasadena.
How Gaming Servers Work Layman’s Explanation: Say you see the enemy right in front of you. LIKE SO
You tell the computer to shoot (Normally by pressing the left button on the mouse) How Gaming Servers Work The data packet is then sent to the server, via traceroutes. The server then receives the information and sends another data packet known as a reply packet which confirms the packet has been received.

It will then calculate whether or not you successfully hit your target. The server decides that you successfully hit your target. It then sends data packets (hit points lost, armor, etc.) to both you and the enemy telling you that the enemy has been hit.
