“…An example of the traffic characteristics between the server and a client of an MMO game is illustrated in Figure 3. For RTS games, interestingly, latency has a negligible effect on the outcome of the game, indicating that RTS game-play clearly favors strategy over the real-time aspects [44].…”

This paper assesses whether multi-path communication can help latency-sensitive applications to satisfy the requirements of their users. We consider Concurrent Multi-path Transfer for SCTP (CMT-SCTP) and Multi-path TCP (MPTCP) and evaluate their proficiency in transporting video, gaming, and web traffic over combinations of WLAN and 3G interfaces. To ensure the validity of our evaluation, several experimental approaches were used including simulation, emulation and live experiments. When paths are symmetric in terms of capacity, delay and loss rate, we find that the experienced latency is significantly reduced, compared to using a single path. Using multiple asymmetric paths does not affect latencyapplications do not experience any increase or decrease, but might benefit from other advantages of multipath communication. In the light of our conclusions, multi-path transport is suitable for latency-sensitive traffic and mature enough to be widely deployed.

“…Sheldon et al describe results from a controlled experiment to investigate the effect of latency on user performance in the real-time strategy game Warcraft III [17]. The results of the experiment show that there is no significant effect on the performance of the players when the latency is increased (from 0 to 3500 ms).…”

This paper describes results and experiences from designing, implementing, and testing a multiplayer real-time game over mobile networks with high latency. The paper reports on network latency and bandwidth measurements from playing the game live over GPRS, EDGE, UMTS, and WLAN using the TCP and the UDP protocols. These measurements describe the practical constraints of various wireless networks and protocols when used for mobile multiplayer game purposes. Further, the paper reports on experiences from implementing various approaches to minimize issues related to high latency. Specifically, the paper focuses on a discussion about how much of the game should run locally on the client versus on the server to minimize the load on the mobile device and obtain sufficient consistency in the game. The game was designed to reveal all kinds of implementation issues of mobile network multiplayer games. The goal of the game is for a player to push other players around and into traps where they loose their lives. The game relies heavily on collision detection between the players and game objects. The paper presents experiences from experimenting with various approaches that can be used to handle such collisions, and highlights the advantages and disadvantages of the various approaches.

“…Real time strategy games like Warcraft III, on the other hand, can tolerate up to several seconds of network latency [35], because the emphasis is on strategy rather than direct interaction. Although there is no study of latency tolerance for MMGs, role playing games are generally considered to have a latency tolerance similar to RTS games, since the player controls the game by telling his avatar what to do, e.g.…”

Peer-to-peer support for massively multiplayer games

Abstract-We present an approach to support massively multi-player games on peer-to-peer overlays. Our approach exploits the fact that players in MMGs display locality of interest, and therefore can form self-organizing groups based on their locations in the virtual world. To this end, we have designed scalable mechanisms to distribute the game state to the participating players and to maintain consistency in the face of node failures. The resulting system dynamically scales with the number of online players. It is more flexible and has a lower deployment cost than centralized games servers. We have implemented a simple game we call SimMud, and experimented with up to 4000 players to demonstrate the applicability of this approach.
