Design and Implementation of an Adaptive Flow Measurement for SDN-based Cellular Core Networks

摘要

Network traffic measurement plays a vital role in network monitoring and management. At present, software-defined networking (SDN) has deeply changed the traditional computer network architecture, providing flexibility as well as scalability in network management. However, measurement of cellular core networks is still challenging due to the complexity and stringent requirements of cellular systems. To monitor SDN-based cellular core networks, an adaptive SDN-based flow measurement method is proposed. With the enrichment of diverse IoT applications, we also design an IoT QoS Provider tailored for IoT traffic. In addition, practical approaches are presented to justify our method and experimental results demonstrate the efficiency of our approach.
