Technology Overview

Game server providers (GSPs) are companies that lease game servers. Gaming clans will often lease one or more servers for their chosen game, with members of the clan contributing to the server rental fees. Game server providers often offer Web tools to control and configure the game servers; most allow those that rent or lease to modify the games being leased.

Dedicated game server
Most games use a dedicated server application. This program collects data from players and distributes it to other players. This is more efficient and effective than a peer-to-peer arrangement, but it requires a separate computer to host the server application. The additional computer is a server.

Network bandwidth, in particularly upstream bandwidth, is often one of the major limitations in hosting game servers. Home broadband Internet connections rarely provide the necessary upstream bandwidth to host dedicated game servers with more than 4-10 clients. In the past, this was the only option available. Typically a player would buy the game and host the server, as well as running the client, on their home computer. Even if the bandwidth provided by the latest broadband services at the time could handle the outbound network traffic the computer itself still struggled to provide a good quality of service to the networked players, while simultaneously running the game on the same machine.

A professional server is a computer to read data and transmit vast amounts of data as fast as players need it. A handful of game hosting pioneers realized the need for such systems. They purchased rack mounted server machines and colocated them within datacenters to host their games. They paid between $200 and $700 a month for this luxury, and the teams that could foot such bills were few and far between, but these setups significantly improved the gameplay. Within a few years online multiplayer gaming became a huge success. Prices have lowered dramatically and renting game servers, or dedicated servers to host game servers on, is something that has become very common for online gaming teams.
[edit] Types of game servers

Game servers can be classified as listen servers and dedicated servers. Listen server refers to a situation in which the server typically runs in the same process as the game client, allowing a player to both host and participate in the game. As a side effect, the server is usually terminated when the client is. Listen servers are operated mostly by individuals, often in LAN Party situations rather than over the Internet, and usually with a lower number of players due to the increased processing and bandwidth requirements associated with operating both server and client simultaneously on the same machine. Dedicated servers are servers which run independently of the client. Such servers may be run by individuals, but are usually run on dedicated hardware located in data centers, providing more bandwidth and dedicated processing power. Dedicated servers are the preferred method of hosting game servers for most PC-based multiplayer games. Massively multiplayer online games run on dedicated servers usually hosted by the software company that owns the game title, allowing them to control and update content. In many cases they are run on clustered servers to allow huge environments and large player counts.
