一种基于本地滞后的一致性控制技术

提出一种满足协同虚拟环境系统协同操作要求的一致性控制技术.给出协同虚拟环境系统的一致性定义,分析了传统网络虚拟环境系统所采用一致性控制方法不能用于协同虚拟环境系统的原因.对系统同步所有节点物理时钟,通过本地滞后技术进行一致性控制,当由于过大的网络传输延迟产生不一致状态时,通过时间扭曲机制进行状态修复.实验结果表明,在不同网络负载下,该技术均能支持多个用户同时对一个对象进行协同操作.

Local lag based consistency maintaining technology

A consistency maintaining technology for collaborative virtual environment (CVE) systems was proposed to satisfy CVE systems' request for cooperation. The definition of consistency in CVE systems was given, and the reason why traditional consistency maintaining technology used in networked virtual environment systems could not be used in CVE systems was analyzed. System synchronized all sites' physical clock and local lag technology were adopted to maintain the system's consistency. When the system' consistency was broken by long network transmission time, system adopted time warp to repair the object's state. Experimental results show that this technology allows multiple users to operate on the same object simultaneously at different network load.
