随着物联网设备数量的增加和智能家居技术的发展，提出了一种基于软件定义网络（SDN，Software Defined Networking）的面向物联网智能家居的ISP（Internet Service Provider）带宽QoS管理框架。本研究的应用范围假设ISP应支持数千个智能家居。每个智能家居都配备了数十个具有广泛功能的物联网设备，每个智能家居都利用了各种服务。整个系统架构分为ISP端的SDN智能家居云和大规模的SDN智能家居。智能家居云通过OpenFlow协议与智能家居互联。在这种架构下，我们首先通过调整3GPP LTE QoS类标识符（QCI）来对智能家居服务进行分类。然后，我们提出了一个智能家庭带宽分配（SHBA）策略，计算适当的带宽为每个服务类别，根据不同的QoS要求。因此，ISP可以使用SHBA来优化智能家居的聚合和分类服务的带宽分配。实验在基于Linux的OpenvSwitch、Ryu控制器和Mininet构建的SDN网络环境下进行。实验结果表明，该框架可以有效地提高服务质量，并优于传统的ISP带宽分配策略的平均传输速率，延迟和抖动。
With the increasing number of IoT (Internet of Things) devices and advance of smart home technologies, we propose a SDN (Software Defined Networking) based QoS (Quality of Service) aware bandwidth management framework of ISP (Internet Service Provider) for IoT enabled smart homes. The application scope of this research assumes that an ISP should support thousands of smart homes. Each smart home is equipped with tens of IoT devices with a wide spectrum of functional capabilities and each smart home exploits a variety of services. The overall system architecture is divided into SDN Smart Home Cloud at ISP side and massive SDN enabled Smart Homes. The Smart Home Cloud is interconnected with Smart Homes through OpenFlow protocol. With this architecture, we first prioritized smart home services into categories by adapting 3GPP LTE QoS Class Identifier (QCI). Then we propose a Smart Home Bandwidth Allocation (SHBA) strategy to calculate appropriate bandwidth for each service category according to distinct QoS requirements. ISP can thus use SHBA to optimize bandwidth allocation of aggregated and classified services of smart homes. The experiments are performed under a SDN based network environment constructed by Linux based OpenvSwitch, Ryu controller and Mininet. The experiment results show that the proposed framework can effectively enhance QoS and outperform the traditional ISP bandwidth allocation strategy in terms of average transfer rate, delay and jitter.
