Abstract

The invention provides a media file back source path determination method and device in a CDN network. The method comprises the steps that finite edge nodes, relay nodes and source station nodes are selected from an edge node layer, a relay node layer and a source station node layer; the path value of a first path segment from a user to each edge node is determined; the path value of a second path segment from each edge node to each relay node is determined; the path value of a third path segment from each relay node to each source station node is determined; and according to the path value of each segment, a back source path is determined, wherein the back source path is the nearest to the user and reaches the source station nodes through the edge nodes and the relay nodes. According to the method, the real-time network conditions of all CDN network nodes are comprehensively considered; the accuracy of the back source path is improved; data transmission delay is reduced; and the user experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of network multimedia technologies, and in particular to a method and device for determining a return-to-source path of a media file in a CDN network. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the required content nearby, solve Internet network congestion, and improve The responsiveness of the user's access to the website. Technically, it fully solves the root cause of the slow response speed of users visiting websites due to reasons such as small network bandwidth, large user visits, and uneven distribution of outlets. [0003] CDN technology is divided into two technologies: dynamic acceleration and static acceleratio...
