摘要

SDN (Software-Defined Networking)分为两个平面:控制平面和转发平面。控制平面从交换机移到独立的集中式控制器中，负责配置交换机并对数据流使用的路径进行编程。承载应用程序的控制器使用OpenFlow协议从OpenFlow交换机收集信息，并操纵数据包的转发。本文的目的是实现一个QoS/QoE映射和调整应用程序，用于ISP在访问服务后监控用户感知的QoE。该应用程序在RYU控制器平台上实现，用于监控基于openvswitch的OpenFlow交换机的性能。实施结果表明，所设计的应用程序能够直接反映用户的感知质量，为ISP提供有价值的信息，以提供更高质量的服务。

The implementation of a QoS/QoE mapping and adjusting application in software-defined networks

Software-Defined Networking (SDN) consists of two planes: the control and the forwarding plane. The control plane is moved out of the switch and into the separate, centralized controller, and is responsible for configuring the switch and programming the paths to be used by data flows. The controller hosting the applications collects information from the OpenFlow switch using the OpenFlow protocol and manipulates the forwarding of packets. This paper is to implement a QoS/QoE mapping and adjusting application that is used by the ISP to monitor the user-perceived QoE after accessing the service. The application is implemented on the RYU controller platform to monitor the performance of the OpenvSwitch-based OpenFlow switch. The implementation results show that the designed application can directly reflect the perceived quality of users and provide the ISP with valuable information for offering higher quality services.
