Abstract

In this paper, a realtime testbed for Software Defined Networks (SDN) was implemented using Raspberry Pi as OpenFlow (OF) switches. The implemented testbed provides practical development and testing environment for SDNs. Open vSwitch (OVS) was used to observe the flows and events in the network. With the POX integration, this paper easily provide detailed analysis results for any testing process. Additionally, this study implemented priority queuing algorithm, which manages the flows with respect to their QoS requirements. Priority queuing is a scheduling mechanism that provides a fixed number of priority levels to different service classes and can be used for differentiated services provisioning. Differentiated service is a QoS architecture that seeks to provide service differentiation to a small number of service classes. Finally, this study physically implemented the proposed algorithm to our testbed and validate the improvements of traffic and network utilization in terms of throughput.

服务质量机制在OpenFlow测试平台上的演示

本文采用树莓派作为OpenFlow (OF)交换机，实现了软件定义网络(SDN)的实时测试平台。实现的测试平台为sdn提供了实用的开发和测试环境。使用Open vSwitch (OVS)来观察网络中的流和事件。通过POX集成，本文可以轻松地为任何测试过程提供详细的分析结果。此外，本研究还实现了优先级排队算法，该算法根据流的QoS要求对流进行管理。优先级队列是一种调度机制，它为不同的服务类别提供固定数量的优先级级别，并可用于差异化的服务供应。差异化服务是一种QoS体系结构，旨在为少量服务类提供差异化服务。最后，本研究在我们的测试平台上物理实现了所提出的算法，并验证了在吞吐量方面对流量和网络利用率的改进。
