Content acceleration method and system

Abstract

The disclosure relates to a content acceleration method and system. The method comprises: a client obtains an IP address of an agent node which the client belongs to from a management control center server and establishes a transparent agency relation with the agent node which the client belongs to; the agent node which the client belongs to receives a request that is sent by the client and is about internet content obtaining and determines whether the request internet content is buffered locally; if the content is buffered locally and is not expired, the content is returned to the client; and otherwise, the agent node which the client belongs to inquires whether other agent nodes buffer the content at the management control center server; if so, the IP address of the agent node with the buffered content is returned to the agent node which the client belongs to; the agent node which the client belongs to establishes connection with the agent node with the buffered content, obtains the content from the agent node, and forwards the content to the client; and if no agent node has buffered the content, the agent node which the client belongs to makes a request about the content to the internet. With the method and system, rapid response of the content can be guaranteed.

Description

technical field [0001] The present disclosure relates to the field of data communication, and in particular, to a content acceleration method and system. Background technique [0002] In existing Internet content acceleration services, CDN (Content Distribution Network, Content Distribution Network) plays a very important role. ISP (Internet Service Provider, Internet Service Provider) can distribute content and data such as videos, web pages, and applications to the edge node of the CDN closest to the user through the CDN, so as to improve the speed of the user's access to the website, especially the Internet with a large amount of data video business. [0003] In a typical Internet access process, CDN is logically a gateway of the website it serves. Internet users need to access the content of the website through the network gateway of CDN. Therefore, CDN usually adopts the reverse proxy method. Serving the accelerated network. [0004] Regardless of whether it is an IS...

AI Technical Summary

Problems solved by technology

Most of the CDN nodes are deployed at relatively high positions, such as in the IDC computer room of a telecom operator, and the QoS (Quality of Service) of this part of the video from the IDC computer room to the user terminal cannot be guaranteed

In addition, the global scheduling of CDN basically judges the proximity based on the user's IP address or local DNS (Domain Name Server, domain name server) address. This kind of judgment is only a rough judgment. The actual distance is not optimal in physical routing

[0008] Most of the existing websites store cookies on the user terminal to identify the identity and access records of Internet users, so as to analyze and record the user's habits and preferences in this website, but it is impossible to know the user's access habits on other websites. Even if a CDN can accelerate multiple websites at the same time, the custom features of the cookies of each website cannot enable the CDN to determine whether the user is the same person, so the working method of the CDN reverse proxy still has certain limitations for the accurate description of user behavior sex

[0009] User-produced content is the development trend of Internet video applications in the future. Users can upload these video content to the website through CDN. Video file upload experience is still not good
