Description
Technical Field
The embodiment of the invention relates to the field of wireless networks, in particular to a remote pushing method, a remote pushing system, a server and a computer readable storage medium.
Background
Multi-access Edge Computing (MEC) is a technology proposed by European Telecommunication Standardization Institute (ETSI) based on 5G evolution architecture to deeply merge base stations and internet services, and NGMN names a related concept as "intelligent Edge node". The multi-access edge computing (MEC) is used as a key technology for the evolution of a 4.5G/5G network system architecture, and can meet the requirements of the system on various aspects such as throughput, time delay, network scalability, intellectualization and the like.
ETSI defines MEC as the ability to provide IT and cloud computing to the edge of a mobile network by deploying a generic server on the wireless access side, emphasizing close proximity to users. The presence of MEC, i.e. the "sinking" of network traffic to the radio access network side closer to the user, brings about three benefits:
1. the transmission delay experienced by the user is reduced.
2. Network congestion is significantly controlled.
3. More network information and network congestion control functions may be open to developers.
In the MEC practical application process, a plurality of independent edge data centers facing a certain area are formed by edge service nodes deployed at the edge of a mobile network through virtualization and clouding, and relevant basic services and industry applications are deployed at the edge data centers so that relevant capabilities of the edge nodes such as calculation, storage, network and the like can be utilized. Compared with a data center of a traditional center cloud, the MEC can be simply understood as an edge data processing platform, namely, the traditional data center is cut into various small data centers and then placed at the edge of a network, so that the data centers are expected to be closer to users, faster service is provided for the users, and better network performance is achieved.
The appearance of the edge nodes breaks through the original cloud-end application deployment architecture. Through a cloud-edge-end application architecture, the effective gain of the application end-to-end time delay and bandwidth is carried out by utilizing the computing and storing capacity of the edge node, which is the main development direction of future application, and the application deployment of the edge node also becomes the key function of the implementation landing of the edge computing application.
In the existing data center application deployment and push architecture, transmission and deployment of corresponding image files need to be performed from a central image node. Under the scene that the edge data center has multiple areas and multiple clusters, application pushing and management adopting the existing centralized architecture will face the problems of more deployed application nodes, unstable cross-area network and the like, and under the concurrent scene, the central node network and the computing capability will face huge challenges. In addition, different clusters where the edge nodes are located are loosely coupled, different areas have different demands on push and deployment applications, and differentiated management of the center mirror image nodes results in that the center nodes need to maintain mirror image version information of each edge cluster in a differentiated mode, so that the logic complexity of processing is brought to the center nodes.
The inventors found that there are at least the following problems in the related art:
in the prior art, for application distribution and deployment in an edge computing scene, a framework of terminal device uploading, central node scheduling and distribution, and edge node deployment and connection is adopted. The application distribution deployment of the corresponding edge nodes depends on the scheduling of the cloud center node, so that the processing efficiency is low.
