基于SDN的物联网架构分析

摘要

With the rapid development of Internet of things in recent years, more and more devices formed a huge physical network, which use a lot of switches and routers to control data forwarding network architecture is becoming more and more complex inefifcient. Aiming at this problem, this article will SDN (Software Deifned Networking) network architecture in the introduction of the Internet of things, in this paper, a forward with perception layer, layer, control layer and application layer 4 layer iot architecture reference model, and to achieve the main function of each part are discussed. Finally, choose the OpenFlow agreement as south interface protocols, analyzes the data forwarding process in architecture. Through the separation of control plane and data plane reference model, and makes the network deployment and management of the Internet of things more convenient.%随着近年来物联网的快速发展，越来越多的设备组成了一个庞大的物理网络，其中沿用大量交换机和路由器来控制数据转发的网络架构变得越来越复杂和低效。针对此问题，文章将SDN（Software Defined Networking）网络架构引入物联网中，提出一种具有感知层、转发层、控制层和应用层的4层物联网体系架构参考模型，并对各部分实现的主要功能进行讨论。最后，选择了OpenFlow协议作为南向接口协议，分析了数据在体系架构中的转发过程。通过控制面与数据面分离的参考模型，使得物联网的网络部署和管理更加方便。
