Bandwidth Consumption Control and Service Differentiation for Video Streaming

Multimedia streaming is resource demanding. It may starve other applications such as file transfer sharing the network, for example, in a smart home. To address the problem, we apply fuzzy logic control to bound the bandwidth consumption of multimedia streams. We also differentiate the video quality for streams with different levels of importance. We have implemented our transmission rate control and service differentiation schemes and evaluated them in our department network where a number of different applications may coexist at the same time. Performance evaluation results show that our video streaming system can support the specified bit rate bound and differentiate the service to efficiently utilize the limited bandwidth.
