Cloud-mist combined internet of things application construction system based on SDN

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...
