Abstract

Distributed simulations that support a massive number of users typically divide the virtual world into zones that are managed by separate servers to evenly distribute resources and achieve scalability. However, such zoning restricts cross-zonal interactions and exposes the division of the world to the participating parties. Problems such as crowding one zone among others defeats the very purpose of interest management and makes geographic partitioning inefficient for modeling interactions. In this work, we have designed and implemented a visibility-driven approach to make the partitioning transparent to users. The effectiveness of this distributed architecture is tested through a prototype implementation. We also introduce a novel idea to dynamic load balancing that can be achieved in real-time without modifying the communication architecture. By increasing the granularity of the partitioning and providing a layered approach to zoning, transient crowding can be handled by adoptively dispersing parts of the crowded zone to adjacent servers.
基于动态负载平衡的分布式仿真兴趣管理的可见性驱动方法
支持大量用户的分布式模拟通常将虚拟世界划分为由独立服务器管理的区域,以均匀分配资源并实现可伸缩性。然而,这种分区限制了跨区域的互动,并将世界的划分暴露给参与各方。将一个区域挤在其他区域中的问题会破坏兴趣管理的真正目的,并使地理划分在建模交互时效率低下。在这项工作中,我们设计并实现了一种可见性驱动的方法,使分区对用户透明。通过原型实现测试了该分布式体系结构的有效性。我们还引入了一种新的动态负载平衡思想,可以在不修改通信体系结构的情况下实时实现。通过增加分区的粒度和提供分层的分区方法,可以通过将拥挤区域的部分分散到相邻的服务器来处理短暂的拥挤。
