Problems solved by technology

[0007] If the sub-CDN that receives the content distribution request does not store the media content requested by the user, or cannot process the content distribution request because of its high load, it will cause multi-level forwarding or even circular forwarding of the content distribution request, thus increasing the processing time of the user. The time for content distribution requests, even infinitely prolongs the time for processing user content distribution requests, especially in the case of a large number of sub-CDNs included in the total CDN, it is impossible to return a response message to the user within an acceptable time, reducing the CDN service quality

Embodiment Construction

[0069] In the embodiment of the present invention, a target CDN that can handle the content distribution request can be directly selected in the CDN system to process the content distribution request, thereby avoiding the problem that the source CDN cannot handle the content distribution request, especially when the CDN scale is large. Multi-level forwarding and even circular forwarding of content distribution requests.

[0070] figure 2 It is a flowchart of an embodiment of the content distribution method of the present invention. Such as figure 2 As shown, the content distribution method of this embodiment includes the following steps:

[0071] Step 101, receiving a content distribution request, the content distribution request includes content information requested to be distributed, and further includes address information of a user terminal (User Equipment, hereinafter referred to as UE) requesting content distribution.

[0072] Step 102, sending a query request to a...

Abstract

The embodiment of the invention discloses a method and a device for distributing contents and a network system for distributing contents, wherein the method for distributing contents comprises the following steps: receiving a content distribution request including the information of contents requested to be distributed; sending a query request including the information of contents requested to bedistributed to a top content distribution network control cell (TOP-CDNC); receiving target CDN related information returned by the TOP-CDNC; and requesting the target CDN to process the content distribution request. The embodiment of the invention can avoid the multilevel forwarding, even cycle forwarding of the content distribution request which can not be processed, effectively save time for processing the content distribution requests from users and return the response messages to the users in time, thereby improving the service quality of the CDN.

Description

technical field [0001] The present invention relates to communication technology, in particular to a content distribution method, device and content distribution network system. Background technique [0002] A content delivery network (Content Delivery Network, hereinafter referred to as: CDN) technology is a technology developed to improve Internet (Internet) service quality (Quality of Service, hereinafter referred to as: QoS). Through the optimized deployment of content, it realizes the nearby access of users to content and the intelligent distribution of network traffic, comprehensively solves the impact of factors such as small network bandwidth, large user visits, and uneven distribution of outlets on user access effects, and greatly improves network access. response speed. [0003] The principle of CDN technology is to deploy media servers in a distributed manner in the network, so that the media content provided by the content provider can be pushed from the backbon...
