Abstract

Current networking devices are limited in their capabilities to dynamically adjust their behaviour with respect to the location changes induced by the mobility of communicating partners. This adversely affects the performance of applications running on top of IP-based wireless networks. Software Defined Networks (SDN) provide the strength of network programability which facilitates on-demand customization of underlying network according to the application context. In this paper, we propose our methodology for seamless mobility in IP-based Wi-Fi networks using SDN. Our solution works for both layer-2 and layer-3 mobility scenarios and is able to cater the needs of Wi-Fi networks. We have evaluated our approach with respect to handover delay, route establishment delay, data loss and throughput both for UDP and TCP traffic. Emulation results obtained establish the applicability of our approach.
基于IP的Wi-Fi网络中的软件定义移动性:设计方案和未来方向
当前的网络设备在根据通信伙伴的移动性引起的位置变化动态调整其行为的能力方面是有限的。这对在基于ip的无线网络上运行的应用程序的性能有不利影响。软件定义网络(SDN)提供了强大的网络可编程性,便于根据应用程序上下文对底层网络进行按需定制。在本文中,我们提出了使用SDN在基于ip的Wi-Fi网络中实现无缝移动性的方法。我们的解决方案适用于二层和三层移动场景,能够满足Wi-Fi网络的需求。我们已经评估了我们的方法关于切换延迟,路由建立延迟,数据丢失和吞吐量都为UDP和TCP流量。仿真结果验证了该方法的适用性。
