A distributed content distribution method, edge server and content distribution network

Abstract

This invention discloses a distributing method for distributed contents, edge servers and a content distributing network, in which, the method includes: setting up an overlap net among multiple edge servers in an edge network, a central server distributes service resource to each edge server ES, which distributes service resource according to the request of the user and includes a content dispatch module used in getting service resources from an upper level server by an upper-level server communication module to finish service dispatch and transmitting the service resource to the user communication module, and multiple edge servers in the edge network of the distributing net form an overlapped network to provide content distribution service to users.

Description

technical field [0001] The invention relates to a data transmission technology of a communication network, in particular to a distributed content distribution method, an edge server and a content distribution network. Background technique [0002] With the rapid development of IPTV services, the efficiency and cost of content publishing have increasingly become the key factors affecting service deployment. In order to solve the above problems, the industry has proposed a solution CDN (Contentdelivery network), which uses the existing Internet Based on the establishment of a new layer of network - content distribution network CDN, dedicated to the efficient distribution of multimedia content through the Internet. CDN greatly improves the response speed of the network by realizing the user's access to the nearest website and the intelligent distribution of network traffic. [0003] The technical principle of CDN is to push the content of the website from the backbone of the n...

Problems solved by technology

[0012] Compared with the CDN network in Figure 1, this solution adds a control node to forward all the requests of all users, which is not a small burden when the number of users is large; and its cache node saves the program The content is allocated by the control node. The cache node itself cannot dynamically increase or decrease the backup node according to the user request. There will be a bottleneck phenomenon when processing popular resources. In addition, the introduction of the control node increases the possibility of single point failure. To avoid this In some cases, it is necessary to focus on maintenance, resulting in increased maintenance costs
