Hadoop平台上的云会议研究

Research of Cloud Conferencing on Hadoop Platform

针对传统多媒体会议规模小、媒体可靠性差和系统鲁棒性弱等缺点,提出一种面向服务基于云计算的多媒体会议-云会议.该系统利用面向服务的思想,采用松耦合结构,将信令、媒体服务相分离;利用云计算的规模大、扩展性和计算能力强的特点,扩大会议规模、高效处理媒体;改进云计算开发平台Hadoop,使其满足多媒体会议需求.实验表明,云会议在规模、可靠性、鲁棒性各方面比现有多媒体会议表现更佳.

Traditional multimedia conferencing has the disadvantages of small conference size,unreliable media stream and weak robustness.Compared with these short points,this paper proposes a service-oriented multimedia conferencing based on cloud computing called cloud conferencing.This system adopts loose coupled structure to dispatch signal and multimedia service followed the service-oriented idea.It utilizes the characteristics of cloud computing,such as huge size,high extension and powerful computing,to enhance the conference size and process media efficiently.We improve the cloud computing platform of Hadoop to meet the demand of multimedia conferencing.The experiments show that cloud conferencing has better performance than traditional ones,such as size,reliability and robustness.
