对现有的云计算平台进行分析和总结，结合移动IPTV的特点，基于Eucalyptus开源云计算平台，提出并设计了一个应用于移动IPTV场景的云计算系统，并对其负载均衡技术予以改进。实验仿真结果表明改进后系统比原有系统的调度算法有明显优势，并更加适合云计算平台，并适合移动IPTV服务的发展。-Cloud computing platform on the existing analysis and summary, combining the characteristics of mobile IPTV, based on Eucalyptus open source cloud computing platform, proposed and designed for mobile IPTV scene of a cloud computing system, and its load-balancing technology to be improved. Simulation results show that the improved system scheduling algorithm than the original system has obvious advantages, and more suitable for cloud computing platform and is suitable for mobile IPTV services.
