【摘要】 网格自90年代中期被提出以来,得到迅猛发展,是目前国际计算机界的热门研究领域之一。网格监测为网格用户和其他组件提供与网格资源有关的重要性能数据,是网格系统进行性能调整和错误发现的依据。因而网格监测系统的建设是网格建设中非常关键的一环,成为重要的研究方向。 本文的主要贡献在于借鉴基于内容的事件通知服务思想,提出并设计一种基于事件通知服务(Event Notification Service,ENS)的网格监测系统。将“基于内容的发布/订阅”通信机制引入到网格监测系统中。 考虑到网格环境是一种跨地域跨组织的广域异构环境,由地理上分布、分属不同管理组织的各类网络构成,本文设计一种“混合结构”的服务器网络拓扑,即采用层次化结构与一般对等结构相混合的方式来建立监测系统的服务器网络。 根据网格资源监测对象的特征,在可扩展的互联网事件通知体系结构(Scalable Internet Event Notification Architecture,SIENA)基础上,本文设计了适用于网格监测系统的数据存储结构和消息格式;在SIENA原始路由转发算法基础上设计了一种基于分类的路由转发(Classification-Based Routing and Forwarding,CBRF)算法。 最后,基于上述框架结构本文设计了一个基于ENS的网格监测原型系统,实现了主要的功能模块,并在局域网内进行了仿真验证。另外,将本文设计的CBRF算法与SIENA原始转发算法做了实验对比,结果表明CBRF算法提高了消息的转发速度。更多还原

【Abstract】 The grid technology has been developed greatly since it was proposed in 1990s, and has become one of the hot researching fields. Grid Monitoring System provides essential and source-related performance data for the users and developers of grid, and it lays the base for grid system to regulate performance and find errors. So how to construct Grid Monitoring System is one of the critical problems of the grid research, and has become an important research direction.This paper designs an ENS-based (Event Notification Service, ENS for short) Grid Monitoring System, which uses "content-based publish/subscribe" as the communication mechanism and is high scalability. The design idea is derived from Content-based Event Notification Service.The grid environment is wide-area heterogeneous environment, which is across wide areas, and it will be consist of many LANs, these LANs are distributed and belong to different organizations. This paper proposes a hybrid topology in constructing the server network of Grid Monitoring System, which is hybrid from hierarchical topology and generic peer-to-peer topology.According to the characters of the object of grid monitoring, based on the SIENA (Scalable Internet Event Notification Architecture), this paper designs data structure and message format which are suitable for Grid Monitoring System. Based on the original routing and forwarding algorithm of the SIENA, this paper designs a classification-based routing and forwarding algorithm.At last, this paper designs a grid monitoring prototype system according the architecture mentioned above, and implements main function modules. In addition, this paper compares the classification-based algorithm with the original algorithm of the SIENA by experiments, and the results show that the classification-based algorithm increases the speed of forwarding message.更多还原
