Problems solved by technology

However, due to the large amount of video content on the Internet, some content is very popular and has a high number of user visits, while the right-hand content is relatively unpopular and has no client access, and the currently popular content may become unpopular after a period of time. Moreover, due to the limitation of CDN's own storage and scheduling capabilities, it can only cache some popular content, and cannot cache most of the video content on the Internet.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] see figure 1 , a kind of CDN transparent caching method based on hotspot mechanism of the present invention, described method comprises the following steps:

[0016] (1a) The user provides the browser with the domain name to be accessed;

[0017] (2a) One of the cache servers in the CDN system obtains the actual IP address of the domain name according to the domain name to be accessed provided by the browser, and the cache server submits an access request to the actual IP address;

[0018] (3a) The cache server saves the content locally after obtaining the content from the actual IP address, and at the same time returns the obtained data to the client;

[0019] (4a) When multiple cache servers in the CDN system store the same content locally, the hotspot mechanism sends the actual IP address to all cache servers in the CDN system;

[0020] (5a...

Abstract

The invention discloses a CDN transparent cache method based on a hot spot mechanism, and belongs to the CDN technical field. The hot spot mechanism is added into a CDN system, a domain name to be accessed is provided by a user to a browser, when a plurality of cache servers exist in the CDN system to conduct local storage on same contents, an actual IP address is transmitted by the hot spot mechanism to all the cache servers in the CDN system, all the cache servers in the CDN system each conduct local storage after obtaining the contents from the actual IP address, overdue and not-popular contents are deleted, and therefore the CDN transparent cache efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of CDN, in particular to a CDN transparent caching method based on a hotspot mechanism. Background technique [0002] The CDN network pushes the content to the edge nodes in advance through a multi-level architecture, and then dispatches the user's service request to the edge node closest to the user based on comprehensive information such as node load, network traffic, distance to the user, and response time. This node provides services for users, which can well solve problems such as network congestion, long response time, and unsmooth video playback. At present, most of the video content is provided by various Internet service providers, and a considerable number of Internet service providers do not build their own CDN or rent a third-party CDN. The video services provided by these service providers are centralized. , lack of CDN control, disorder and other characteristics, it is easy to cause proble...
