Inconsistency is a challenge with many delaysensitive Massively Multiplayer Online Games (MMOGs). In this paper, a framework for inconsistency analysis and control is proposed. A typical situation, called hot-spot region, is considered for resolving this problem, since it is one of major causes of the inconsistency. Stochastic models are presented to abstract the operations of a MMOG in the context of our goal, particularly for examining the impact of various system characteristics and player behaviors on the inconsistency. A definition of game inconsistency together with a method for computing inconsistency rate is also provided. By using our models, we carry out inconsistency analysis quantitatively and obtain a deep insight into its behavior. Based on our analysis, we develop a mechanism for inconsistency control in the context of hot-spot region, so as to illustrate our approach in this area.

“…The delay also causes another problem, called game inconsistency. A typical example of the inconsistency is "a dead man who is able to shoot" problem [4][5] [6]. It is recognized that the inconsistency becomes one of key challenges for many MMOGs design.…”

Online games are more and more popular, resulting in an increasing share in the Internet traffic. These games generate a huge number of packets with typically small payloads, which overloads the network and deteriorates its efficiency. To mitigate these problems, it was proposed to use the tunnelling, compression and multiplexing (TCM) technique. Even though it was claimed via a set of emulations that this technique would enhance the network performance, there were no theoretical nor simulation studies to demonstrate its benefits on online gaming experience. In this paper, we implement TCM in NS-3 and set up online games scenarios in order to evaluate the performance of this technique in terms of delay, jitter and order of packets. The results show that with TCM the delay and jitter are more important than the native traffic for a small number of players due to the multiplexing periods. However, this situation is reversed when the number of players is high. Furthermore, the disorder of packets is always more important with TCM. In order to reduce the delay and the packets disorder, we propose a scenario where the online players are partitioned into subgroups based on their location on the game map. Simulations show that this leads to a significant performance improvement.

In this paper we discuss that the specific consistency and latency requirements of world state updates in Massively Multi-User Virtual Environments (MMVEs) are determined by several characteristic factors of the virtual world, i.e. their Interaction Context. As this context is highly application-dependent, MMVE developers require a simple specification scheme which allows them to specify these requirements for their specific Interaction Contexts. In this paper we present such a scheme, which we believe represents an important step towards dynamic and flexible consistency management for MMVEs.
