Proxies provide redundant points of communication entry. Thankfully, one of the solutions to help drive dedicated server workloads to more redundant and distributed orchestration is the utilisation of traffic proxies!īy using a proxy for multiplayer UDP traffic, in front of our dedicated games servers within a low latency network such as what is available on Google Cloud, we can address these key challenges as follows: If we look at both web and mobile technologies over the past several years, some of these challenges start to look very familiar. Multiple aspects of game server simulation and network communication are tightly coupled in the same process, making reuse and modularity more difficult, and expanding risk of performance issues. The IP and port of connection to the game server is public, and exposed to the game client, making it easy to discover and target. This makes it a target for malicious actors. If it goes down, then the whole game session (or sometimes multiple sessions) fails. Since the entire state of the game is memory resident, each client connects directly to the dedicated game server the player is playing on, which presents several challenges:Įach dedicated game server is a single point of failure. In fast-paced, multiplayer games, the full simulation of a session of gameplay generally occurs within the memory of a monolithic dedicated game server, whose responsibility covers everything from network physics and AI simulation to communications from client back to server and more. Challenges with multiplayer Game Server communication This reusable foundation then allows game developers to spend more of their time focusing on building the game-specific aspects of building their multiplayer communication protocols, rather than these common aspects. Provide this common functionality in a composable and configurable way, such that it can be reused across a wide set of multiplayer games. Pull common functionality, such as security, access control, telemetry and metrics out of monolithic dedicated game servers and clients. This communication is most often bundled into monolithic game servers and clients, pairing the technical functionality of communication protocols, such as custom network physics synchronisation, security, access control, telemetry and metrics, with the extremely high computational requirements of physics simulations, AI computation and more.ĭeveloped in collaboration with Embark Studios, Quilkin is a UDP proxy, tailor-made for high performance real-time multiplayer games. Traditionally, dedicated game servers for real time multiplayer games have used bespoke UDP protocols for communication and synchronization of gameplay among the players within a game.
