中文摘要：

网格资源的表示、组织、部署、发现、创建、使用和撤销是网格计算的重要研究问题，随着Web services技术和服务网格理念的逐步成熟．以“服务”的方式来包装网格资源已经成为了一种趋势，并得到了网格界的一致认同。由于网格资源的“充足性”及“共享性”．采用池的方式来组织网格资源，以及把网格资源包装成服务，是一种很合理的方式。用户对网格的一次访问过程包括访问场景的创建．访问的实施．以及实施完成后的撤销，具有生命期的特征，而这正是虚拟组织所具有的功能．基于虚拟组织来设计服务访问模型是很合理的。基于物理资源池、服务池以及虚拟组织的思想，文章提出了面向服务网格的通用框架模型及服务访问模型VSP，VSP模型被用于指导HowU信息处理平台的设计。

英文摘要：

The representation,organization,deployment,discovery,creation,usage,destruction of resources are important research problems of grid computing.As web services and the thought of service grid are becoming mature,it becomes a trend that grid resources are capsulated by service,which is well accepted by grid field,Because the resources have the properties of sufficiency and sharing in the grid system,it is reasonable for grid resources to be organized by the “pool”.An access from a grid user includes the access scene＇s creation,execution,and destruction after the access is completed,which can be done by virtual organization.Based on physical resource pool,service pool and virtual organization,a general framework and service access model,VSP,is proposed in this paper.HowU information processing platform is designed according to the VSP model.
