Bandwidth distribution for applications in slicing network toward SDN on vCPE framework

This paper presents a novel quality-of-service (QoS) management system for SDN networks with the feature of distributing bandwidth for applications in different slicing networks. Thus, the applications in different sliced networks (different divisions of an enterprise) can have different bandwidth management policies. The proposed system is also integrated into a vCPE framework to achieve network function virtualization and easy management. Users are able to subscribe the QoS services for different applications via the proposed web-based user interface. Experiment results demonstrate that the proposed system architecture and algorithms are able to provide efficient QoS services with minimal overhead.
