With the development of the network applications and services (e.g., video conferencing and streaming, online gaming, e-commerce, etc.), the user experience is becoming increasingly important. For network operators, deploying effective Quality of Service (QoS) technologies is a key approach to ensure a high-quality user experience. Despite a large volume of works from both academia and industry, QoS has not been completely deployed in today's networks. The primary reasons are the complexity of proposed QoS solutions and largely manual per-device configuration of QoS knobs by network administrators. Software-defined networking (SDN) provides a promising alternative due to its centralized global network view, flexible match fields and the separation of the control plane and data plane. In this paper, we present S5, an application sensitive QoS assurance system via SDN. In S5, we propose a novel QoS measurement framework based on the vertical QoS mapping between the metrics at different network layers. Based on the precise and fine-grained QoS measurement, our system provides a series of QoS guarantee mechanisms, including intelligent call admission control, optimized queue management, and QoS-routing, to guarantee the QoS metrics for the corresponding application. We implement a prototype to validate the feasibility and effectiveness of our system, and get inspired results.
