为了增加分布式虚拟环境系统的规模可扩充性,在经典的客户/服务器(C/S)结构中引入P2P的概念,提出了复合分布式虚拟环境结构.理论上对该结构下中心服务器的负载进行了建模分析,并利用仿真试验对该结构进行了试验验证.该结构在系统客户规模增大时,动态地利用客户端资源减弱服务器端的负载,在相同的服务器硬件条件下拓展系统的客户可扩充性,同时中心服务器的存在还保持了C/S结构易于管理的特点.而由于临时服务器退出导致的服务器负载“抖动”问题,可通过更优化的临时服务器选取策略以及控制临时服务器的客户规模来加以减弱.理论分析和仿真试验表明,动态复合结构融合了C/S结构和P2P结构的优点,可有效改善DVE系统的规模扩充性.
In order to increase the scale scalability of distributed virtual environment system, the concept of P2P is introduced in the classic client / server (C / S) structure and a composite distributed virtual environment structure is proposed. Theoretically, the load of the central server under this structure The model was analyzed and the structure was tested by the simulation test.When the scale of the system was increased, the structure dynamically utilized the client resources to weaken the server-side load and extended the system’s customers under the same server hardware conditions Scalability, while the presence of the central server also maintains the C / S structure is easy to manage features.Because of temporary server out of the server load caused by the “jitter” problem, through a more optimized temporary server selection strategy and control of the temporary server customers The scale to be weakened.Theoretical analysis and simulation experiments show that the dynamic composite structure combines the advantages of C / S structure and P2P structure, which can effectively improve the scalability of DVE system.
