Embodiment Construction

[0096] Specific embodiments of the present invention will be described in detail below.

[0097] like figure 1 As shown, a cloud computing network architecture includes:

[0098] The infrastructure layer is mainly composed of sensor nodes and smart terminals. The sensor nodes and smart terminals are connected through wireless links to collect data and send the collected data and data processing requests to the fog computing layer;

[0099] The fog computing layer is connected to the infrastructure layer. The fog computing layer is composed of multiple edge network devices with weak computing and storage capabilities. The edge network devices are the fog nodes of the fog computing layer. The fog nodes are connected by wireless links. It is used to process the data of the infrastructure layer, and send the data processing results to the sensor nodes or intelligent terminals of the cloud service layer and the infrastructure layer;

[0100] The cloud service layer is connected t...

Abstract

The invention relates to a cloud and fog computing network architecture and a method for enhancing the reliability of the cloud and fog network architecture. A cloud and fog computing network architecture, including an infrastructure layer, a fog computing layer and a cloud service layer. The method for enhancing the reliability of the cloud-fog network architecture includes the following steps: (1) constructing a weighted undirected graph of the cloud-fog network architecture; (2) constructing a business processing delay optimization model when the fog computing layer in the cloud-fog network architecture is faultless; 3) Construct the average delay optimization model of business processing in the cloud-fog network architecture when the fog computing layer is faulty; (4) The delay optimization in the case of no fault in the fog network and the average delay optimization strategy in the case of a fog network fault.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a cloud and fog computing network architecture and a method for enhancing the reliability of the cloud and fog network architecture. Background technique [0002] The rapid development of technologies such as cyber-physical systems (CPS), Internet of Things, big data, cloud computing, and industrial wireless networks has promoted the arrival of the fourth-generation industrial revolution, namely Industry 4.0. The Industrial Internet of Things (IIoT) is one of the key technologies for implementing Industry 4.0. In the Industrial Internet of Things, the massive amount of smart devices and sensing devices connected to the network generates an explosion of data that needs to be processed and stored. At the same time, in the context of Industry 4.0, more and more industrial Internet of Things applications, such as intelligent production, industrial automation and o...
