Title
Framework and user migration strategy of cloud-based video conference multi-gateway system
Abstract
In video conference system, the multimedia gateway plays an important role in forwarding audio and video data, whose performance is a bottleneck of the system. A flexible framework of cloud-based video conference multi-gateway system is proposed to meet the needs of a high-definition video conference system, which can control a variety of virtual gateway resources based on physical devices, thus multimedia gateways can be deployed dynamically. In addition, a real-time user migration strategy is designed and implemented based on the framework, which combines active pattern with passive pattern. The experiments show that the user migration strategy could control the time delay of user migration under 65 milliseconds, ensure the continuity of audio and video data during user migration, and successfully solve the reliability problems caused by system shutdown or overload of the multimedia gateway.
