基于软件定义网络的物联网网络管理关键技术研究

The Internet of Things (IOT) has important research significance and practical value because it’s increasingly extensive applications and the unresolved issues of network management. According to the research object of the network management model and protocol design, the topic divides massive multi-source heterogeneous network management problem into the following categories which is caused by the large number of nodes and diversification of data type:.Firstly, we need make use of the centralized management and custom programming to build the IOT’s network management architecture which is based on the software defined network structure and the foundation of analyzing the traditional network management protocol and pattern;.Secondly, we need build the network management model through abstracting the device of the IOT and extracting the management information;.Thirdly, we need encapsulate the various events and massages and propose a network management interface programming language and in order to improve effectively improve management efficiency and performance, we need transform the network management from manual mode into the program mode according to the IOT to give the optimize compilation;.Finally, we achieve a simple, easy to use, scalable and open Common Cloud Management Platform, for example, the IOT equipment management cloud platform of smart home..This subject puts forward new ideas and theoretical basis for the further research and application of IOT network management which are the network management modeling, device abstract methods and management of programming language.
