Abstract-Understanding the impact of network conditions on player satisfaction, which is one of the major concerns of network game designers, is a popular research topic. Of the various ways to gauge user satisfaction, in this paper, we focus on how network quality affects a player's decision to leave a game prematurely. To answer this question, we analyze a 1, 356-million-packet trace from a large commercial MMORPG called ShenZhou Online.We show that both network delay and network loss significantly affect a player's decision to leave a game prematurely. It is feasible to predict whether players will quit prematurely based on the network conditions they experience. The proposed model can determine the relative impact of different types of network impairment. For our traces, the degrees of player intolerance of network delay, delay jitter, client packet loss, and server packet loss are in the proportion of 1:2:4:3 approximately. The model can also be used to make system design decisions. Through simulations, we show that by prioritizing server processing according to the goodness of network conditions, employing de-jitter buffers, or replacing TCP with a more lightweight transport protocol, the probability of premature departure can be significantly reduced. In this way, we demonstrate how our model of players' network experience provides feedback for the design of online games.

“…First, this index is correct, since the rate of commands sent by slow and fast clients is homogeneous and comparable. Second, each client remains connected for a certain amount of time that has a pre-defined average value [43]. There are many motivations that justify this choice in the model parameterization: mainly, slow clients are usually modem connected, hence they pay for time of connection, and, also, they may experience sudden death of their avatars due to connection delays.…”

Abstract-In recent years many popular interactive computer games have gained online remote multiplayer functionalities, supported by standard Internet communication protocols and architectures. Due to the heterogeneous communication infrastructures and network asymmetries, some users (i.e. clients) may be suffering slow, congested and unreliable Internet connections, while others may have access to fast and reliable links. A different rate and latency in the delivery of users' commands and event notifications may lead to unfairness issues during the game play, specifically, for the class of real time and interactive games. A dynamic adaptation of the gaming architecture to the limitations of the communication infrastructure could be exploited to reduce these problems. In this paper we present a simple client migration algorithm which can be adopted on a generic multiplayer, multiserver online gaming architecture. Client migration among the servers of the gaming infrastructure is exploited to adapt to the dynamic performances of the general communication network infrastructure. The proposed mechanism has been modeled and simulated for the class of distributed multiplayer and multi-server interactive games, implemented over a general communication network infrastructure. Results show a significant fairness improvement, more homogeneous performances, and the absence of significant overheads.
