The multipoint control unit (MCU) is a very important component of the video conferencing system. In the current video conferencing system, the hardware performance of MCU equipment has more demand with the different requirements of video conferencing type. At the same time, with the physical location of the participants is different, flexibility of the MCU geographical location is also higher. Room size of video conferencing and the number of participants can't match well, resulting in waste

... resources. With the emergence of cloud computing, its advantages (ondemand self-service, broad network access, resource pooling, rapid elasticity, measured service) provide new ideas for solving the problems faced by traditional video conferencing MCU. This paper implements a scheme to deploy software MCU on the cloud platform OpenStack based on the fuel environment, analyzes the advantages of this scheme, and provides a valuable idea into the deployment of MCU to cloud computing.
