Embodiment Construction

[0027] The following specifically introduces the system architecture involved in the embodiment of the present invention. The implementation of the present invention involves the concept of network autonomous domains, and those skilled in the art can use appropriate technology to divide according to the specific network structure and characteristics according to the needs of the business; for example, the network service provider point (POP, Point Of Presence) Based on the establishment of network autonomous domains, usually the closer to the network service provider point, the smaller the line signal loss, and the higher the bandwidth guarantee for connecting users. The present invention does not intend to limit the method for establishing and dividing network autonomous domains. The following embodiments assume that a network autonomous domain is established on the basis of a POP point, and use this as an example to specifically describe the implementation of the embodiment ...

Abstract

A method for distributing file data includes: obtaining a first request message of a first client for downloading a first file, and determining an autonomous system (AS) where the first client is located; searching the AS for edge servers that support peer to peer (ES-Ps), and returning the address of at least one ES-P storing the first file to the first client; and sending the first file stored in the ES-P to the first client according to the client information returned by the ES-P. Related devices and systems are also provided. The present invention may speed up the file data distribution, reduce the restriction of the file data distribution due to fixed bandwidth of the ES, and enable P2P data streams to be converged into an AS, thus reducing the impact on backbone networks.

Description

technical field [0001] The present invention relates to content distribution technology, especially a method and system for content distribution in a content / media distribution network and related equipment. Background technique [0002] With the development and popularization of multimedia communication, people's demand for Internet content and applications is growing rapidly. In order to solve the problem of slow Internet connection speed in the original network, a content / media distribution network (Content / media Distribution Network, CDN / MDN) technology. [0003] The content distribution network (CDN) is a network architecture and an overall system based on content distribution technology. Content distribution technology is a distribution cache (Cache) technology developed on the basis of traffic management, load balancing and distributed technology. It adopts the method of placing the cache server at the edge node of the Internet, and transfers the file content from t...
