Content distribution service resource optimized dispatching method based on multi-cloud architecture

Abstract

The invention belongs to the field of cloud computing and network multimedia technology, and particularly relates to a content distribution service resource optimized dispatching method based on multi-cloud architecture. The method comprises the following steps: selecting an initial deployment stage on multi-cloud, and providing a cloud selection initial deployment heuristic algorithm based on charging strategies of a plurality of candidate public service resource providers; in a multi-cloud expansion stage, providing two different multi-cloud expansion methods in a predictable ARIMA model and a cloud outburst scene; and in a multi-cloud switching stage, copying content resources in a newly started data center in batches at a delay as short as possible based on a pre-copied Precopying strategy. By adoption of the content distribution service resource optimized dispatching method, the automatic optimized deployment of a streaming media application in a multi-cloud environment is solved, when the access flow increases abruptly, the volume of the cloud architecture is smartly expanded, and when a certain private cloud data center or a certain public cloud crashes or occurs a serious bandwidth problem, how to quickly switch the cloud service is solved.

Description

technical field [0001] The invention belongs to the field of network multimedia technology and cloud computing technology, and specifically relates to a content distribution service resource optimization scheduling method based on a multi-cloud architecture. Background technique [0002] The digital content industry occupies a very important position in the application of the next generation IP network. In the new generation of Internet, with the development of broadband, Internet applications have shifted from simple Web browsing to comprehensive applications centered on rich content. The distribution services of rich media content will account for an increasing proportion. Streaming media, IPTV, Applications such as large file downloads and high-definition video have gradually become the mainstream of broadband applications. According to Cisco's 2016 video network survey report, video traffic accounted for more than 70% of the entire Internet traffic in 2015. The inheren...
