基于交换操作和再分配的区域-服务器动态分配算法

Dynamic allocation algorithm of region to servers based on swap operation and redistribution

为了提高分布式虚拟环境中用户的交互性,作者提出了一种区域-服务器的动态分配算法.具体实现是在服务器和所管理的区域之间不断执行交换操作,来达到动态地再执行区域-服务器的分配,以提高分布式虚拟环境中用户的交互性,并给出了何时执行再分配和如何执行再分配的条件.仿真结果表明,提出的方法不仅能减少全部用户的平均通信延迟,而且降低了服务器CPU的使用率.

A dynamic allocation algorithm of regions to servers is proposed in this paper to enhance the inter- activity of users in distributed virtual environments. The concrete implement is that swap operations are continu- ously executed among servers and regions controlled by servers to achieve dynamically redistribution of regions to servers, and enhance the interactivity of users in distributed virtual environments. The aim is that the interactivity of users in distributed virtual environments is enhanced and the conditions on when to carry out the rearrangement and the way how to carry out the rearrangement are given. Simulation results show that the methods proposed not only reduces the average communication delay of all clients, but also decreases the usage rate of servers CPU.
