How Gaming Servers Work

• When a person is playing a game from his or her computer on the net, it connects to game servers such as these

• The following is a basic idea of how information is sent from your computer to the server as well as other computers on the network:

• When a person is playing a game online, what’s a little more important is not the speed but rather the amount of hops, traceroutes, that the data packets from the computer have to bounce through (routers/switches) to get to its destination.

How Gaming Servers Work• The moment When you input information from your computer it

bounces. • Here is a technical example:

Tracing route to 209.179.21.10 over a maximum of 30 hops

Trace complete.


• 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.

You tell the computer to shoot (Normally by pressing the left button on the mouse)

The data packet is then The data packet is then sent to the server, via sent to the server, via traceroutes. The server traceroutes. The server then receives the then receives the information and sends information and sends another data packet another data packet known as a reply packet known as a reply packet which confirms the packet which confirms the packet has been received.has been received.

How Gaming Servers WorkWhile at the same time, the server calculates your position in 3D space, the direction of the projectile, and takes the position of the enemy in 3D space and his movement speed and direction. 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.

“CONGRATULATIONS!!! YOU HAVE ELIMINATED THE ENEMY” - SERVER


• This is the basic idea of how information is sent between gamers and the server.

• KEY TERM: Replication – Taking data from a given client and replicating it (duplicating + adding to it) back to all the clients.
