提出了一种可动态伸缩的基于贡献和半贡献多媒体Web服务设计方案,方案利用Internet中的闲置计算资源,以低成本的方式构建分布式Web服务,并设计和实现了Web服务的高效访问定位算法和动态的负载均衡算法,使系统保持动态稳定。经实践,该系统有良好的可扩展性和稳定性,能够适应计算资源的动态变化,设计达到了预期目的。
A scheme based on dedicated and half-dedicated Web service with dynamic scalability is presented to construct the distributed Web service by idle computing resources at a low cost. The design of efficient access and load-balance makes the system maintain dynamic stable. The practice validates the good scalability and stability of the system,and its adaptability to the dynamic computing resources.
