Abstract
Description
technical field
[0001] The invention relates to communication technology, in particular to a method, system and node for interconnecting content distribution network nodes. Background technique
[0002] The content delivery network (Content Delivery Network, CDN) is to add a new layer of network architecture to the existing IP network, and publish the content to the "edge" of the network closest to the user, so that the user can obtain the required content nearby. CDN is composed of multiple CDN nodes, forming a tree or network structure. Nodes with lower network positions are closer to users. Nodes closer to users generally store the hottest content, that is, the content with the highest access frequency, so as to realize the nearest service to users. The purpose is to reduce the loss of upper-level network bandwidth. A CDN node is generally composed of multiple media server clusters, and provides streaming media services to several users at the same time.
