Content distribution method for crowdsourcing, center node and edge node

Abstract

The invention discloses a content distribution method for crowdsourcing, a center node and edge nodes. All or part of edge nodes are directly deployed on a device or a module with local area network-wide area network access functionality with a topology distance being zero hop from an owner's network. The device and the module intelligently prefetch and / or cache content resources to be accessed and / or accessed by a user respectively; and the central node manages the device or the module and the content resources in different modes according to different service scenes, detects and predicts theidle resource condition of the equipment or the module in real time or at regular time, and uses the idle resources to serve other users with relatively short topological distances in the network. The service quality of the content distribution network is improved in most scenes, the operation expenditure is saved for content providers, and meanwhile, part of earnings are fed back to terminal users who contribute to calculation, networks or storage resources.

Description

[0001] This case is a divisional application based on the patent application with the application number 201510086043.0, the application date is February 24, 2015, and the title is "A Crowdsourcing Content Distribution Network System, Method and Device". technical field [0002] The invention relates to the field of network communication, in particular to a content distribution method for crowdsourcing, a central node and an edge node. Background technique [0003] In the commercial operation of the Internet (Internet), since most services adopt the C / S (client / server) mode, on the one hand, a small number of central servers have limited bandwidth and storage capacity, and cannot serve thousands of users, especially When a large number of user requests influx in an instant, it is easy to become the bottleneck of the entire network service; on the other hand, due to the geographical distance from the user and the network topology distance may be far away, and may span multiple...

Problems solved by technology

[0017] The technical problems to be solved by the present invention are: in order to solve the bottleneck of the bandwidth and processing capacity of the central server of the content provider, the pressure on the ISP backbone network, the high cost of CDN operation and use, and the inability of seamless integration and flexible scheduling of CDN and P2P systems, etc., the present invention Invent to build a layered and crowdsourced content distribution network on the "zero-hop" device or module closest to the end user, such as a smart router or a web browser, and design a set of business operation methods that benefit all parties
