Abstract

The embodiment of the invention provides a content delivery network active cache delivery method and system, and the method comprises the steps: building an consortium blockchain model for a content delivery market based on a content delivery network cache delivery model of a blockchain; and based on the consortium blockchain model and a smart contract technology, prefecthing content delivery network content, and performing self-organization in the delivery process. According to the embodiment of the invention, the consortium blockchain model of the content delivery market is constructed, theself-organization of the content prefetching and delivery process of the content delivery network is realized by utilizing the smart contract technology, and the credible auditing of the content delivery network main body is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a content distribution network active buffer delivery method and system. Background technique [0002] Global mobile data traffic has grown 18-fold due to the explosion in mobile video traffic. At present, most mobile communications are asynchronous, and content sending requests are repeated. In recent years, active caching technology has received widespread attention. [0003] Typically, proactive caching consists of two phases, the first phase is the prefetch phase, during which edge servers such as Wi-Fi access points (APs) and small cell base stations (SCBSs), even support device-to-device ( D2D) nodes pre-download / copy content from content servers (CSs) before any mobile user issues a content request; the second phase is the delivery phase, where content is delivered from caching nodes to mobile users via backhaul or D2D links. In content delivery networks (...
