Abstract
We analyse the network traffic of the online multiplayer first person shooter game Enemy Territory. The game is based on the Quake 3 game engine but has more complex gaming rules. The data analysed is taken from a public game server run at CAIA, and corresponds to real gaming traffic. Measuring the packet length, inter-arrival time and bandwidth in both directions, this paper describes the impact of map, number of players or client hardware on the traffic. We find the traffic characteristics of Enemy Territory are very similar to the characteristics measured for Quake 3. However, there are some slight differences we point out. We also introduce activity as a new parameter that influences the traffic statistics such as packet length distributions.
