Background
The Internet of things is an expanded application and network extension of a communication network and the Internet, and the Internet of things utilizes a sensing technology and intelligent equipment to sense and identify the physical world, carries out calculation, processing and knowledge mining through network transmission and interconnection, realizes information interaction and seamless link between people and objects, and realizes the purposes of real-time control, accurate management and scientific decision making of the physical world.
With the rapid development of the related technologies of the industrial chain of the internet of things, the traditional industry and the internet of things become a necessary way and an effective way for upgrading and modifying the industry. With the continuous integration and innovation of the traditional industry and the internet of things, the number of the network edge side terminals is continuously increased, and the resource demand for the network is more and more. Due to the limited bandwidth carrying capacity of the network, the traditional cloud-based centralized computing processing mode has difficulty in meeting the requirements of a large number of edge devices. In order to solve the problem of network resource demand, an edge computing technology is introduced based on a traditional cloud centralized computing processing mode, and the problem of network resource demand is effectively solved. Edge computing means that an open platform integrating network, computing, storage and application core capabilities is adopted on one side close to an object or a data source to provide nearest-end services nearby. The application program is initiated at the edge side, so that a faster network service response is generated, and the basic requirements of the industry in the aspects of real-time business, application intelligence, safety, privacy protection and the like are met. The edge computing technology has the characteristics of low time delay, high speed and the like, and is widely realized in a plurality of application scenes of the internet of things nowadays.
However, although the edge calculation effectively solves the problem of network resource requirement, as the algorithm and application technology of the edge terminal gradually develop, the difficulty of adapting to the underlying device increases. Manual physical adaptation is time consuming, labor intensive and extremely costly. Meanwhile, the traditional application deploys and uses the virtual machine, and virtualization provided by the virtual machine needs to consume a large amount of resources, so that the whole system becomes heavy, and meanwhile, the function expansion is more limited, the expansion is difficult, and the service performance is reduced. Therefore, in order to solve the above problems, the container technology is adopted in combination with the edge calculation to effectively improve the network efficiency.
A container is a technology that a developer packages a developed application (system) and a required development environment, and then the application can run on different computers through the container without reconfiguring the relevant environment, except that each computer needs to configure a container engine for running the container. The container technology has the characteristics of extremely light weight, second-level deployment, easiness in transplantation, elastic expansion and the like. However, in the prior art, no efficient containerized edge computation engine exists.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1, the provided containerized edge computing intelligent service engine system architecture includes an edge device side, a containerized edge computing module, and an edge application management platform. In this embodiment, the containerization edge calculation module generally includes a containerization module S2, a container orchestration module S3, and an edge computing container platform S4. The edge device can be various types of electronic devices, and when the edge device responds to the edge intelligent service, the containerized edge computing module is used for more effectively utilizing network resources, so that the network redundancy is effectively reduced, and the network performance is improved.
The containerization edge calculation module is used as a core module of the invention and mainly relates to a containerization technology, a container arrangement technology and the like. Referring to fig. 2, for the containerization module S2, the containerization technology is used to containerize the edge intelligent service at the edge computing service node, and based on the characteristics of the container technology, such as extreme light weight, second-level deployment, easy transplantation, and elastic expansion, the cost of the edge intelligent service can be effectively reduced, and the network throughput and performance can be improved. For example, container 1 is used for data analysis, container 2 is used for state awareness, container 3 is used for node self-inspection, container N is used for edge intelligence application services, and the like.
As shown in fig. 3, for the container arrangement module S3, the edge computation center node in the edge computation network monitors and predicts the network in real time by using the control module, and then reallocates the network resources of the edge computation service node cluster by using the container arrangement technology according to the monitoring result, so as to effectively utilize the network real-time resources. By organizing the containers and operating according to a plan, network resources can be reasonably scheduled in real time.
The architecture of the edge computing container platform S4 is shown in fig. 4, where nodes in a cluster are composed of edge intelligent devices, and can be divided into three types, i.e., edge center nodes, edge network nodes, and edge service nodes. Each node is provided with a Docker operating environment, for example, and operates different numbers of containers, and a container cluster is formed among the containers to provide services to the outside. Wherein the edge center node is responsible for controlling the orchestration of the distributed clusters. The control node is the brain of a node cluster in the converged network and is responsible for monitoring, managing and scheduling computing, storage and network resources in the network. The control node communicates with the edge intelligent device responsible for network forwarding through an OpenFlow protocol, and grasps the network topology in real time. The edge network node is an intelligent node responsible for network switching and provides a data switching function as a switching node in the cluster. And a network topology is constructed among the edge network nodes to complete platform networking. The edge network node can also construct a wireless AP as an access point of the network, and provides wireless network access capability. The edge service node is an intelligent node responsible for providing container services, is directly connected with the edge network node, operates and utilizes a virtualization function provided by the Docker engine to host the container-based Internet of things service.
It should be noted that, in the container platform architecture based on edge computing, in consideration that all containers in a single-node container cluster share resources such as memory and CPU on one host, a node needs to have higher resource configuration, and a node with low configuration cannot be effectively utilized. Based on the container platform architecture of the edge computing, different network nodes in the edge computing network are energized, and different node functions are utilized, so that cluster resources are effectively scheduled.
In summary, because the bandwidth carrying capacity of the network is limited, it is difficult for the traditional cloud-based centralized computing processing method to meet a large amount of requirements of the edge devices. The invention provides a containerized edge computing intelligent service engine, which solves the problem of the requirement of massive edge equipment on network resources by using edge computing and container technology and improves the network performance and the network resource utilization efficiency. In short, based on the container technology of the edge computing intelligent service, the edge computing intelligent service is containerized by using the characteristics of edge computing nodes, so that the intelligent service is more portable and lighter; based on the container arrangement technology of the edge computing intelligent service, the edge computing network architecture is utilized, and the container arrangement technology is used for edge computing in the network through the edge computing center node, so that each edge computing node can more effectively containerize the edge computing intelligent service, and the network resources of the edge computing nodes are more effectively utilized; furthermore, by expanding the single-node container cluster into a multi-node container cluster, the low-cost nodes are fully utilized to run the containerization edge cloud platform service.
