Embodiment Construction

[0039] With the rapid advancement and implementation of "Made in China 2025", the Internet of Things technology has been vigorously developed and widely used. The number of IoT smart applications and terminal devices with various functions has increased rapidly. The application scenarios involve all aspects of social life. The number of connections brought by it is also growing explosively, and more and more industries are using the power of the Internet of Things to improve efficiency and release the huge potential of industrial innovation. Some industry applications are limited by access bandwidth and cost, and need to aggregate and preprocess the traffic uploaded to the data center. Therefore, a network edge that integrates connection, computing, storage, and application installation capabilities is required near the source of objects or data. The open platform, that is, the edge fog computing platform, is generally implemented on the IoT gateway in consideration of its loca...

Abstract

The invention discloses a cloud-mist combined internet of things application construction system based on a SND. The whole architecture orderly comprises a hardware facility layer, a mist processing layer and a cloud computing layer from bottom to top; the mist processing layer is composed of multiple OpenCPS multi-mode gateways; the whole architecture of the OpenCPS multi-mode gateway orderly comprises a network access layer, a virtualization layer, an API pool layer and an application realization layer form bottom to top. The system disclosed by the invention has the advantages as follows: (1) the dynamic regulation on a network resource can be realized, and the management is easy; (2) the whole structure is reasonable in construction, the delay is reduced by using a cloud-mist combinedframework, and the utilization rate is improved by using the SDN architecture. The system can quickly integrate into the internet of things market, multiple internet of things communication protocolsare both taken into consideration, so that the system can be preferably adapted to the transition of the internet of things market demand.

Description

technical field [0001] The invention relates to an Internet of Things application construction system, in particular to an SDN-based cloud and fog combined Internet of Things application construction system, belonging to the technical field of the Internet of Things. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new type of network innovation architecture, by separating the control plane of network equipment from the data plane, and using the standard API to program the data layer, so as to realize the flexibility of network traffic control. SDN separates the control plane of the network from the data forwarding plane, thereby realizing programmable control of the underlying hardware through the software platform in the centralized controller, and realizing flexible on-demand deployment of network resources. In SDN, network devices are only responsible for simple data forwarding, and general-purpose hardware can be used, while t...
