大规模分布式虚拟环境（DVE）已经成为分布式应用的主要趋势，主要是由于多玩家在线游戏在娱乐行业中的巨大流行。由于基于网络服务器的体系结构似乎不足以支持大规模的多玩家应用程序，对等（P2P）体系结构已被提出作为一种有效的和真正可扩展的解决方案，这种系统。然而，为了设计高效的DVE基于对等体系结构，这些系统必须被表征，测量不同的客户端行为对系统性能的影响。本文提出了对等分布式虚拟环境中的分布式系统中的知名性能指标的实验表征。表征结果表明，由于对等方案，系统饱和本质上是避免的，因为它可以预期的。此外，这些结果表明，给定客户端的饱和度仅对虚拟世界中周围的客户端有影响，对其余化身没有明显的影响。最后，表征结果表明，提供给客户端计算机的响应时间在很大程度上取决于新的连接，这些客户端必须使新的邻居出现在虚拟世界中的数量。这些结果可以作为一个有效的对等DVE系统的设计的基础。
Large scale distributed virtual environments (DVEs) have become a major trend in distributed applications, mainly due to the enormous popularity of multi-player online games in the entertainment industry. Since architectures based on networked servers seem to be not scalable enough to support massively multi-player applications, peer-to-peer (P2P) architectures have been proposed as an efficient and truly scalable solution for this kind of systems. However, in order to design efficient DVEs based on peer-to-peer architectures these systems must be characterized, measuring the impact of different client behaviors on system performance. This paper presents the experimental characterization of peer-to-peer distributed virtual environments in regard to well-known performance metrics in distributed systems. Characterization results show that system saturation is inherently avoided due to the peer-to-peer scheme, as it could be expected. Also, these results show that the saturation of a given client exclusively has an effect on the surrounding clients in the virtual world, having no noticeable effect at all on the rest of avatars. Finally, the characterization results show that the response time offered to client computers greatly depends on the number of new connections that these clients have to make when new neighbors appear in the virtual world. These results can be used as the basis for an efficient design of peer-to-peer DVE systems.
