QuakeWorld
QuakeWorld, developed by id Software, is an enhanced multiplayer-focused version of Quake that utilizes UDP ports 27500 through 27900 for network gaming communication. These ports enable player discovery, real-time gameplay data exchange, and server management within the QuakeWorld network, supporting its fast-paced first-person shooter multiplayer environment..
QuakeWorld is a modified client-server architecture designed to enhance online playability of the original Quake released in 1996 by id Software. It uses a range of UDP ports, primarily 27500 through 27900, for facilitating session initiation, gameplay data transfer, and server communication. This design helps reduce latency, thereby improving the online experience for players using dial-up or other network connections at the time.
QuakeWorld servers listen on these UDP ports for incoming player connections and real-time game state updates, such as player movements, actions, and environment changes. Since it operates predominantly on UDP, which is connectionless, it achieves faster packet delivery by forgoing built-in reliability measures like retransmission, favoring speed over guaranteed delivery—crucial in fast-paced gaming scenarios.
Aside from player gameplay data, these ports also handle game session management tasks like server queries, player authentication, and customization data. The use of a wide port range supports running multiple game servers or sessions concurrently, enabling scalability within competitive multiplayer gaming environments.
