目前,很多高性能光网络平台能为网格计算环境动态提供按需专用光路,以满足e-Science等上层应用的数据密集性需求。为了更有效共享和管理光网络的光路资源,提出了一个基于Web服务的光路封装及其提前预留管理模型。详细描述了其运作机制和软件模块构成,并扩展语义Web中资源描述框架(RDF)来描述光网络中的光路资源。这有助于将光路资源以有状态Web服务形式发布并调用,及应用Web技术自动完成光路资源信息更新和管理。
Currently, many high-performance optical network platforms provide on-demand on-demand optical paths for grid computing environments dynamically to meet the data-intensive needs of top-tier applications such as e-Science. In order to share and manage the optical resources of the optical network more effectively, an optical path encapsulation based on Web Services and its advance reservation management model are proposed. Described in detail its operating mechanism and software module composition, and extends the Semantic Web Resource Description Framework (RDF) to describe the optical network resources. This is helpful for the optical path resources to be distributed and invoked as stateful web services, and the web technology is used to automatically update and manage the optical path resource information.
