Aspects of networking in multiplayer computer games

Abstract

Abstract-Distributed, real-time multiplayer computer games (MCGs) are in the vanguard of utilizing the networking possibilities. Although related research have been done in military simulations, virtual reality systems, and computer supported cooperative working, the suggested solutions diverge from the problems posed by MCGs. With this in mind, this paper provides a concise overview of four aspects affecting networking in MCGs. Firstly, networking resources (bandwidth, latency, and computational power) set the technical boundaries within which the MCG must operate. Secondly, distribution concepts encompass communication architectures (peer-to-peer, client/server, servernetwork), and both data and control architectures (centralized, distributed, replicated). Thirdly, scalability allows the MCG to adapt to the resource changes by parametrization. Finally, security aims at fighting back against cheating and vandalism, which are common in online gaming.

Massive Multiplayer Online Gaming: A Research Framework for Military Training and Education

“…Smed, Kaukoranta, and Hakonen (2002) note that the variance in latency measures is known as "jitter," and suggest that in MMOGs an acceptable latency might range from 0.1 to 1.0 seconds. In effect, higher latencies might be acceptable as long as there is minimal jitter.…”

Performance modeling of multicast groups for multiplayer games in peer-to-peer networks

“…Jouni Smed et al [2] give an excellent review on networking and multiplayer computer games. The author of the current paper benefits their work from the conceptual view of multiplayer games.…”

“…This is based on "Network Virtual Environment Information Principle" in [2] by Singal and Zyda. It is simply expressed in information principle equation as follows:…”

“…Therefore, a natural way to save bandwidth is to disseminate update packets only to those peers who are interested in them. The basic idea for implementing this approach is to divide a game or its virtual environment into "interest" multicast groups [2] [6][7] [8]. There are different strategies to perform such division.…”
