摘要 发言权控制允许网络上的多个多媒体应用的用户使用和共享远程设备、分布式的数据集合和像视频、音频这样的连续媒体而不至于发生访问冲突。发言权是动态分配给协同工作环境下用户的暂时的访问权,其目的是为了缓和竞争条件和保证互斥地使用共享资源。该文首先描述了远程教育虚拟的教室中的发言权控制策略,然后给出了一个发言权控制的API。 Floor control allows users of networked multimedia applications to utilize and share resources such as remote devices,distributed data sets,or continuous media such as video and audio without access conflicts.Floors are temporary permissions granted dynamically to collaborating users in order to mitigate race conditions and guarantee mutually exclusive resource usage.This paper first describes the control policies of floor in virtual learning of distant education and then presents an API of floor control.
