Abstract: 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.
