“…For example, our analysis indicates that the average local avatar count is 1.59 across all 125 regions. This is inline with previous work, e.g., Varvello et al [11] report that 45% of regions are empty, while only 2% of them have global avatar counts higher than 20. Hence, we do not consider avatar counts.…”

Virtual worlds, such as Second Life, are computer-simulated spaces divided into multiple regions, in which each user controls an avatar to perform actions (such as run and fly) in order to interact with other users. From a set of publicly available Second Life traces [1], we find that Second Life incurs diverse traffic patterns in different regions and with different actions. We therefore propose region-and action-aware Second Life clients, which adapt to and take advantages of the diverse traffic patterns for user-specified optimization criterion. For example, to prolong battery life, a mobile Second Life client switches from high capacity WiFi network to energy efficient cellular network when a Second Life client incurs low bit rate traffic. To efficiently achieve this, we propose a parameterized traffic model to accurately predict Second Life traffic patterns. We systematically derive the traffic model parameters using public Second Life traces, and we validate the model accuracy using another set of real network traces. To the best of our knowledge, region-and action-aware Second Life clients have never been considered in the literature, while the proposed parameterized traffic model is of interest in its own right, for Second Life developers, researchers, and Internet Service Providers (ISPs).

“…Mean playing time in WoW, for example, has been measured as 168 min (10080s) [109], with players staying for at least an hour and usually not longer than five hours per session. In Second life, 50% of users stay connected for less than 10 min (600s), 15% stay connected for 100 min or more and 5% of users stay connected for more than 10 hours [116].…”

“…Each test had 3 runs and each run lasted for 10 minutes. In this experiment the users' avatars spend 80 to 90 percent of their time standing and doing nothing as Varvello et al (Varvello et al, 2008) describe. The remainder of the time was spent walking around.…”

Abstract:Multi User Virtual Worlds provide a simulated immersive 3D environment that is similar to the real world. Popular examples include Second Life and OpenSim. The multi-user nature of these simulations means that there are significant computational demands on the processes that render the different avatar-centric views of the world for each participant, which change with every movement or interaction each participant makes. Maintaining quality of experience can be difficult when the density of avatars within the same area suddenly grows beyond a relatively small number. As such virtual worlds have a dynamic resource-on-demand need that could conceivably be met by Cloud technologies. In this paper we make a start to assessing the feasibility of using the Cloud for virtual worlds by measuring the performance of virtual worlds in virtual machines of the type used for Clouds. A suitable benchmark is researched and formulated and the construction of a test-bed for carrying out load experiments is described. The system is then used to evaluate the performance of virtual worlds running in virtual machines. The results are presented and analysed before presenting the design of a system that we have built for managing virtual worlds in the Cloud.
