Abstract

The paper proposes to use a solution based on software-defined networks (SDN) to control traffic flows in wireless local area networks (Wi-Fi). The paper examines the testing methods for a software-configurable wireless local area network based on the model network of the St. Petersburg State University of Telecommunications. Classify traffic based on DSCP values in the IP-headers of packets. After classification, traffic will be given priority over the OpenFlow port of the switch. This method allows for end-to-end quality support and support for traffic classification when interworking. In the course of practical experiment, the interaction of access points (AP), which are emulated in Mininet with the SDN controller, is considered. When using the OpenDaylight controller, the network topology can be controlled through the user-friendly graphical interface (GUI) of the SDN. As a result, methods were examined using DSCP values for QoS management in SDN networks.

基于SDN概念的无线局域网流量集中控制

本文提出了一种基于软件定义网络(SDN)的无线局域网(Wi-Fi)流量控制方案。本文研究了基于圣彼得堡国立电信大学模型网的软件可配置无线局域网的测试方法。根据报文ip头中的DSCP值对流量进行分类。分类后的流量将优先通过交换机的OpenFlow端口。这种方法允许端到端质量支持，并在互通时支持流分类。在实际实验过程中，考虑了在Mininet中仿真的接入点(AP)与SDN控制器之间的交互。使用OpenDaylight控制器时，可以通过SDN的GUI (user-friendly graphical interface)对网络拓扑进行控制。因此，研究了在SDN网络中使用DSCP值进行QoS管理的方法。
