Video service processing method and system based on software defined network and edge computing technology

Abstract

The invention relates to a video service processing method and system based on a software defined network and an edge computing technology, and the method comprises the steps: transmitting video request information to an SDN controller when a local cache of a standard edge node does not have a target video, determining the popularity of the target video through the SDN controller according to the video request information and a video popularity model, determining a standard configuration edge node of the target video to be cached according to the popularity of the target video; enabling the SDN controller to determine a high configuration edge node for processing the video request information according to the video request information, and enabling the high configuration edge node to send the target video to the terminal according to the video request information and the flow table information. According to the method, intelligent hotspot analysis is provided for the high-definition video service through the global management capability of the SDN controller, and the requirements of agile connection and the like of the ultra-high-definition video service of a terminal user can be met. The high-configuration edge node increases a special adaptation scheme for special requirements of ultra-high-definition video processing, and the number of devices is greatly reduced, so the system investment is reduced.

Description

Technical field[0001]The present invention relates to the field of information processing, and more particularly to a video service processing method and system based on a software definition network and an edge computing technology.Background technique[0002]As the scale of the Internet grows, the number of users is increasing, and the traditional network architecture has exposed a variety of issues, such as distributed deployment, poor controllable resistance, poor mobility. These disadvantages have seriously restrictions on the rapid development of network technology, so there is an urgent need for a network architecture that breaks this situation. Software-Defined Networks, SDN is thereby successfully. The nature of the software definition network is to achieve the decoupling of the control plane and data plane, so that the network administrator can control the entire network through software programming. Compared to traditional networks, SDN separates the control plane and data ...

Problems solved by technology

[0002] As the scale of the Internet continues to grow and the number of users continues to increase, the traditional network architecture exposes various problems, such as distributed deployment, poor controllability, poor mobility, etc.

These shortcomings seriously restrict the rapid development of network technology, therefore, there is an urgent need for a network architecture that can break this situation
