摘　　要：虚拟计算环境中存在着极为丰富的资源,但由于其系统的动态性与自治性特点非常突出,系统服务质量很难得到保证。本文提出一种基于资源池的资源聚合方法,即根据应用需求将所需资源聚合成资源池,并以资源池的形式为用户提供服务,使得在任务执行过程中即使部分节点由于系统故障、超载等原因中途退出任务处理,用户的服务请求仍能得到处理和响应。此外,该方法结合负载均衡,优化了资源节点的选择与资源池的构建,从而有效地提高了系统服务质量。The Internet has become an important information infrastructure which can provide unprecedented amount of resources. However, the resources are inherently dynamic and autonomous, which leads to difficulties in providing high quality of services （QoS） in the Internet-based virtual computing environment （iVCE）. We propose a resource-pool-based resource aggregation approach to provide a certain QoS support in the iVCE. Resources are aggregated in a resource pool according to the requirements of applications. Using the resource pool, tasks can be carried out smoothly even when some nodes are spontaneously offline due to a system failure, overload or any other reasons. A load balancing algorithm is introduced to optimize the strategy of node selection and resource pool provisioning.
