Example Embodiment

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

[0097] Such as 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 a wireless link 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 consists 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 through wireless links. Used to process data at the infrastructure layer and send the data processing results to the cloud service layer and sensor nodes or smart terminals in the infrastructure layer;

[0100] The cloud service layer, connected to the fog computing la...

Abstract

The invention relates to a cloud computing network architecture and a method for enhancing the reliability of the cloud network architecture. The cloud computing network architecture comprises an infrastructure layer, a fog computing layer and a cloud service layer. The method for enhancing the reliability of the cloud network architecture comprises the following steps: (1) constructing a weighted undirected graph of the cloud network architecture; (2) constructing a time delay optimization model of business processing in the cloud network architecture when the fog computing layer is not broken down; (3) constructing an average time delay optimization model of business processing in the cloud network architecture when the fog computing layer is broken down; and (4) constructing the time delay optimization strategy under the condition that the fog network is not broken down and constructing the average time delay optimization strategy under the condition that the fog network is broken down.

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...
