MEC (Multi-access edge computing) technology meets the stringent latency requirements of some applications by deploying computing and storage resources, which may be considered as cloud servers running on the edge of a mobile network and running specific tasks, on the edge of the network. The feature of low delay brought by the MEC technology has also prompted the generation of a large number of edge applications, and more various edge applications are deployed at the edge of the network to perform application services such as real-time control calculation. The invention aims to solve the problem of how to meet the requirement of convenient and quick deployment of a large number of edge applications.

Currently, edge applications are typically deployed at the edge of a network in two ways:

first, a technician is relied on to manually deploy an edge application to a specific edge application data center, and the specific process is as follows: firstly, a technician logs in an edge cloud management system, manages a cloud resource dashboard or a similar human-computer Interface to execute deployment operation by using a Graphical User Interface (GUI) Interface in the edge cloud management system, wherein the deployment operation comprises the following steps: creating virtual links, routes and connection points for the edge application, wherein the virtual links, routes and connection points are required for communication; when an operating virtual machine is created for an edge application, a mirror image file is required to be uploaded to a cloud management system, a virtual machine mirror image is created by using the mirror image file, and then a virtual machine is created by using the virtual machine mirror image; after the virtual machine is established, logging in the virtual machine, and uploading edge application software to the virtual machine; and then setting an IP address required by the edge application on the virtual machine, and finally running the edge application. Each step of operation requires the participation of a technician, which is cumbersome.

The manual deployment mode is complicated, only one APP can be deployed in one operation, in addition, the requirement on technical personnel is high, the technical personnel who require to deploy the edge application must be familiar with the operation of the edge cloud management system, and the efficiency is low when the edge application is deployed in the mode.

The second method is to deploy the edge application in a manner of a development framework supporting application service deployment, which simplifies the deployment process of the edge application to some extent compared with the first manual deployment method, but deploying the edge application by using the development framework imposes more restrictions on the design of the edge application, such as having to use a fixed development framework when designing and developing the edge application, and needing to deploy the application in a deployment environment defined by the development framework.

Therefore, the deployment of the edge application cannot be conveniently and quickly realized no matter in the first manual deployment mode or the second development framework deployment mode. Especially for complex applications, such as a scenario where an application is cooperatively operated by a plurality of sub-applications distributed on a plurality of virtual machines and there is a complex network connection between the plurality of sub-applications, deployment may become more difficult.

Based on this, the embodiment of the invention provides an edge computing application deployment method and system, which are used for solving the problem that the efficiency of deploying edge applications in a manual deployment mode in the prior art is low, and can conveniently and quickly complete deployment of the edge applications. The method and the system are based on the same inventive concept, and because the principles of solving the problems of the method and the system are similar, the implementation of the system and the method can be mutually referred, and repeated parts are not repeated.

To facilitate understanding of the embodiment, a detailed description is first given of an edge computing application deployment system disclosed in the embodiment of the present invention.

As shown in fig. 2, the NFVO, VNFM, and VIM function modules are independent of each other and intercommunicate with each other through standard interfaces, such as the interface reference point Or-VNFM between the NFVO and VNFM, the interface reference point Or-Vi between the NFVO and VIM, and the interface reference point Vi-VNFM between VNFM and VIM shown in fig. 2.

The NFVO and the edge cloud management system 500, the VNFM, and the VIM respectively perform direct communication, and serve as input and output interfaces of the management orchestration system 300 for external communication, and the NFVO may forward the received software deployment package and instantiation request sent by the edge cloud management system 500 to the VNFM, and may also receive feedback information of the VNFM, for example, when the VNFM receives the software deployment package, feedback information that the NFVO receives success.

And the VNFM is configured to, when the instantiation request is received, search for a target software deployment package matching the identifier of the software deployment package from a plurality of software deployment packages sent by the edge cloud management system 500 received in advance.

And the VIM is used for creating virtual machines for the N to-be-deployed edge applications according to the target software deployment package found by the VNFM so as to deploy the N to-be-deployed edge applications on the virtual machines.

The VNFM is further configured to send a data configuration notification to the edge application configuration system 400 after the VIM creates the virtual machine for the N edge applications to be deployed, where the data configuration notification is used to notify the edge application configuration system 400 to perform service data configuration on the N edge applications to be deployed on the virtual machine, so as to complete deployment of the N edge applications to be deployed. The Service data includes data information such as QoS (Quality of Service) parameters, uplink and downlink forwarding rules, and communication protocols.

In the embodiment of the present invention, the management orchestration system 300 automatically completes deployment of the edge application to be deployed through interaction operations of the internal NFVO, VNFM, and VIM and interaction with the edge cloud management system 500 and the edge application configuration system 400, which simplifies the deployment process and improves the deployment efficiency, and does not need operations by professional technicians, and can conveniently and quickly complete deployment of the edge application compared with a manual deployment manner in the prior art.

The target software deployment package comprises an operating system image file, N software version files of the edge applications to be deployed and N resource demand files which correspond to the N software version files of the edge applications to be deployed one by one, wherein the ith resource demand file is used for indicating virtual resources required for deploying the ith edge application to be deployed; wherein the virtual resources include at least one of: computing resources, network resources, and storage resources.

The Hypervisor, also called VMM (Virtual Machine Monitor) or a Virtual Machine manager, is a set of system software, and provides platform virtualization, such as a Virtual Machine (VM), for a user to run its own operating system and application program, which may be the edge application to be deployed described in the embodiments of the present invention. In addition, the Hypervisor provides an isolation technology between the virtual machines, so that the virtual machines can run independently from each other, and different virtual machines can run different operating systems.
