Abstract

The invention discloses a CDN bandwidth scheduling system comprising a CDN node, a monitoring center, a scheduling subsystem and a scheduling center, wherein the monitoring center obtains machine room quality information of the CDN node and sends the machine room quality information to the scheduling center; the scheduling center calculates a machine room bandwidth quota of each machine room according to obtained machine room cost information, the machine room quality information and service quality information; and the scheduling subsystem updates a scheduling strategy according to a user request number, user bandwidth flow and the machine room bandwidth quota sent by the scheduling center. According to the CDN bandwidth scheduling system, the scheduling center is set to achieve the decoupling of CDN bandwidth scheduling and service scheduling via a hierarchical design, the scheduling subsystem provides the scheduling of service demands, the scheduling center controls the bandwidth quota of the scheduling subsystem while taking both of the quality and the cost into account, and thus the overall quality and cost are optimal.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a CDN bandwidth scheduling system and method. Background technique [0002] With the development of the Internet, more and more contents are downloaded on the Internet, including pictures, audio and video files, software or games. In order to improve downloads such as large software, games or video files. In order to solve the problem of network congestion, large-scale network service providers generally adopt the following strategies to alleviate the pressure of network congestion: use CDN (full name in English is Content Delivery Network, full name in Chinese is Content Distribution Network) service, by placing node servers everywhere in the network, A layer of intelligent virtual network is formed on the basis of the existing Internet. The CDN system can redirect user requests in real time according to comprehensive information such as network traffic, connection of each...
