Technical Field
The invention relates to the technical field of networks, in particular to a Content Delivery Network (CDN) processing method and a system.
Background
The video CDN refers to a network system capable of providing a real-time downloading function for an online video service. The method can avoid bottlenecks and links which possibly influence the data transmission speed and stability on the Internet as far as possible, so that the content transmission is faster and more stable. The scheduler and the video server are two important components in the video CDN. In the application process of the video CDN, a user sends a data request to a scheduler before going to a video server to download video file fragments each time, the scheduler allocates a video server to the user according to various information such as strategy configuration, user IP and the like, and the user downloads the video file fragments through the allocated video server.
In a currently-used video CDN system, if a download speed of a video server a allocated by a user X for accessing a scheduler is slow, the video server a should notify the scheduler of this information in real time, so that when the scheduler performs scheduling, a scheduling priority of the video server a for serving the user X is reduced. As shown in fig. 1, in the existing architecture, since the video server a does not know which scheduler the user X will access next time, in order to transmit information for reducing the scheduling priority of the user X served by the video server a to the scheduler, the video server a must first send the information to the scheduling central control server, and then the scheduling central control server issues the information to all the schedulers, so that the function of reducing the scheduling priority of the user X served by the video server a can be realized no matter which scheduler the user X accesses next time. The flow process is complex, consumes much time, issues redundant information to too many irrelevant schedulers, and has poor operability, so that the video server cannot quickly and conveniently feed back information to the schedulers.

In step S120, the scheduler list is obtained according to the user information carried when the video server accesses the domain name system DNS.
Optionally, the video server may obtain the scheduler list by using an ECS (Edns-Client-Subnet) extension protocol, for example, if the user IP is 202.108.14.240, and the domain name to which the scheduler belongs is data. digdata. video. qiyi.com + subnet ═ 202.108.14.240@ ns1. qiyi.com.
Step S130: and the video server compares the scheduler IP accessed by the user last time with the scheduler IP in the scheduler list.
Step S140: and if the scheduler IP accessed by the user last time exists in the scheduler list, the video server sends the user IP, the user identification ID and the data downloading speed to all schedulers in the scheduler list.
In step S140, the data download speed is a data download speed at which the video server sends data to the user through calculation when the user access is finished.
Specifically, when the user access is finished, the video server counts the total number of bytes of the requested data when the user accesses and the total time for the user to download the data, and the total time is calculated according to the formula: and calculating the data downloading speed as the total byte number/total time.
