Problems solved by technology

Although this method of obtaining resources can ensure that the mobile terminal obtains the corresponding content, due to the long transmission link and many nodes accessing the upper-level node, it will cause problems such as large return delay and heavy load on the upper-level node, and will lead to The download volume of cached network content of many service nodes is small, that is, the problem of low cache hit rate

Abstract

The embodiment of the invention discloses a content distribution method, a content service node and a storage medium. The method applied to the domain core management and control node of the domain includes: receiving a content acquisition request forwarded by the first content service node, wherein the content acquisition request is that the first content service node cannot provide the content acquisition request to The target content is forwarded; according to the content acquisition request, query the cache status information of all content service nodes in the domain to determine whether there is a second content service node in the domain that can provide the target content; when there is a second content service node in the domain that can When the second content service node providing the target content sends the node information of the second content service node to the first content service node, wherein the node information is used for the first content service node Obtain the target content from the second content service node.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a content distribution method, a content service node and a storage medium. Background technique [0002] Content Delivery Network (CDN) is an overlay network composed of server groups distributed in different regions, which can publish content to the place closest to the user, and can be based on network traffic and the connection and load of each node Comprehensive information such as status and distance to the user directs the user's request to the optimal node. [0003] CDN can effectively increase user access speed, reduce network traffic impact, and accelerate service deployment. It has become an important infrastructure for the Internet and operator services, and is widely used. [0004] The Mobile Content Delivery Network (MCDN) is mainly for mobile users. By deploying edge service nodes on the mobile access network, closer to the location of mobile users, it can reduce...
