Bo Bai, Jihong Zhao, Hua Qu · 2013
With the quick development of service-oriented network, the services of streaming media and their traffic has become a rather important part in the circumstance of virtual network. However, there hasn't been a unified control mechanism to maintain the qualities of these services. The QoS of streaming media is a great concern of current network, and it'll be vital in future network because of the rapid growth of internet users and traffics. This paper describes a mechanism of maintaining the survivalbility of streaming media service in the circumstance of overlay network. We propose a method to calculate the health value of each path and service. Through this mechanism we can evaluate the current quality of services and provide information for further decisions. As a proof of concept we implement an experimental scenario to assess the functionality and the availability of this mechanism. It has managed effectively in the evaluation of streaming services.
