【摘要】 开放网格服务结构(OGSA)定义了一类专门用于实现创建新网格服务实例的接口-Factory,并提供了在网格服务中创建、管理和交换信息的机制。虽然,client／proxy可以动态地创建网格服务实例,但是不能创建网格服务。同样,OGSA也缺乏动态配置网格服务的机制,而不能适应网格环境中的资源的动态性。引入了一种可扩展的网格动态服务结构,提出了一些新的网格服务。在这些服务中,client／proxy可以动态地上传用于构建新服务所需的服务代码。Java以及run-time环境使得开发、测试和配置网格服务更具灵活性。更多还原

【Abstract】 The open grid services architecture (OGSA) provided mechanisms for creating, managing and exchanging information among grid services by factory porttype. Client/proxy can dynamically create new grid service instances but not new grid services. Current OGSA lacks mechanism for dynamically deploying grid services and doesn’t adapt resource change in grid. An extensible grid dynamic services architecture is introduced. This architecture provides some new grid services that are absent in current OGSA specification. By these new services, client/proxy can dynamically upload service codes needed to establish new services. Java-based development and run-time environment can make developing, testing and deploying grid services more flexible.更多还原
