doi:10.3969/j.issn.1000-0801.2012.03.020

Abstract

Abstract:

This paper presents a cloud-based media server system architecture,provides a method of cloud media server scheduling,and then analyzes the application of the media server based on Cloud Computing.This kind of media server system can accord current traffic load to automatically adjust the system performance,to meet business requirements.This kind of media server system can build a media resources pool,and the maximizing equipment utilization can be achieved.So it will lower the network operatorsˊ business operating costs

Key words: media server, cloud computing, elastic extension
