Adding congestion control and fail-over functionality to a UDP-based multiplayer framework
2012 (English)Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
Abstract [en]

The goal of the project was to improve a multiplayer framework for games by adding a system for congestion control and a fail-over system that would allow a client in a game to take over as host if the original host were to crash or leave the game. An existing game engine was used for the project. The methods that were used to detect network congestion was to check for network packet loss and increased packet round-trip time at the frameworks network layer. When network congestion was detected, the application would adapt the amount of network data sent to avoid flooding the receiver. The fail-over system used a lobby that both the games host and clients would register themselves with. When the host was shut down, the lobby would choose a new host among the clients and start the fail-over process which involved converting a game client to a game server, having clients connect to the new host and synchronizing the game worlds of the games new host and its clients. While the fail-over system worked relatively well the congestion control system had some issues with detecting packet loss and insufficient testing.
