Streaming media on demand method based on Hadoop and virtual streaming media server cluster

Abstract

The invention discloses a streaming media on demand method based on Hadoop and a virtual streaming media server cluster. The virtual streaming media server cluster is constructed on a virtual machine server cluster, and directly acquires stored streaming media file data from a Hadoop storage cluster to realize streaming media on demand. Particularly, in the method, a virtual machine server management node monitors the service conditions of memory and network bandwidth resources of the virtual streaming media server cluster in real time to realize the dynamic scheduling of virtual streaming media servers; hotspot file prefixes on the Hadoop storage cluster are deployed on the virtual streaming media servers according to a virtual streaming media server cluster balanced-deployment principle; requests of users are cached at intervals on the virtual streaming media servers according to a time sequence; and cache sizes on each virtual streaming media server are controlled and a virtual machine scheduling strategy is triggered according to the file reading bandwidth of the virtual streaming media server cluster for the Hadoop storage cluster.

Description

Technical field [0001] The invention relates to a storage resource based on Hadoop (a distributed storage cluster with high fault tolerance, high transmission rate and access in a streaming manner) and a virtual streaming media server deployed on a blade machine, using virtual machine scheduling strategies and files On-demand method of caching strategy. Background technique [0002] With the increasing application of Internet technology, video-on-demand services have become an important part of people's daily lives. The quality of video-on-demand services largely depends on the support of the back-end on-demand server. There are many ways to build a back-end on-demand server. The applicant has found three patents related to streaming media server systems or streaming media on-demand methods after a new search. They are: [0003] 1. Dynamic load method of streaming media service (application number: 200610106932.X) [0004] 2. A clustered streaming media server system suitable for l...

AI Technical Summary

Problems solved by technology

[0006] The problems common to the above-mentioned existing patents are: the streaming media servers are basically real servers and do not involve virtual streaming server clusters; the dynamic load method distributes user requests in a balanced manner based on the load conditions of the servers, regardless of The user's hotspot degree; the background data reading bandwidth is not considered, so the virtual machine interval cache size cannot be dynamically controlled
