Crowd-sourced content delivery network system, method and device

Abstract

The invention discloses a system, a method, a device and a computer program product. The system, the method, the device and the computer program product are used for establishing a crowd-sourced content delivery network on a zero hop device or module closest to a terminal user. The system comprises a center and an edge. Servers or functional modules of the edge are all or partly arranged on devices or modules directly, wherein the devices or the modules are a zero hop distance away from an owner network topology and have a local area network-wide area network access function, and the devices and the modules each intelligently prefetch and / or cache content resources which the user is going to have access to or has had access to. The center manages the devices or the modules and the content resources in different modes according to different service scenes. The idle resource situations of the devices or the modules are detected and forecasted in real time or regularly, and idle resources are used for serving other users with the short topology distances in a service network. The service quality of the content distribution network is improved in most scenes, the operation expenses are saved for content providers, and meanwhile part of earnings are fed back to the users.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a system, method and device of a crowdsourcing content distribution network. Background technique [0002] In the commercial operation of the Internet (Internet), since most services adopt the C / S (client / server) model, a small number of central servers, on the one hand, have limited bandwidth and storage capacity, and cannot serve thousands of users, especially When a large number of user requests flood in instantly, 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 ISPs (Internet Service Providers, Internet Service Providers). or operator), the transmission path is prone to network congestion and jitter, as well as the operator's speed limit, etc. [0003] In the above case, the user cannot obtain better QoE (Quality of...

Problems solved by technology

[0016] In order to solve the bottleneck of bandwidth and processing capacity of the content provider center server, the ISP backbone network is under heavy pressure, the CDN operation and use costs are high, and the CDN and P2P systems cannot be seamlessly integrated. Flexible scheduling and other issues, the present invention builds a layered and crowdsourced content distribution network on the "zero-hop" devices closest to end users, such as smart routers and web browsers, and designs a set of commercial services that benefit all parties.
