摘要
本文首先从网格技术的发展历程出发,阐述了网格技术从计算和数据网格向服务网格发展的重要趋势。由宽带业务发展产生的新需求展开分析,指明了新型的服务网格技术对于宽带业务模式革新具有重大的支撑作用。从我们的研究课题出发,提出了面向服务的电信宽带网格整体技术架构,然后主要阐述了该架构应用服务层和应用基础架构层两个层次的主要功能和实现机制,具体包括内容分发服务网格、多媒体在线游戏服务网格、宽带小区协同服务网格三个应用和资源,用户,安全,业务管理等基础服务机制。最后总结了服务网格给电信宽带业务模式转变带来的重大革新价值和未来的发展方向。
From development course of grid technology, this paper introduces the mainstream trend of grid technology from computational grid to service grid. Based on the analysis of the new demand produced by broadband industry development in telecom field,we illustrate the grand value which the novel service grid technology brings for broadband business model innovation. From our research program ,we propose a service-oriented broadband grid technology framework and study in detail a series of key technologies in this field ,from application service layer to application infrastructure layer,including Content Delivery Service Grid,Multimedia Online Game Grid,Telecom Broadband District Cooperative Service Grid and such basic service mechanism as resource, user, security, and business management. At last, we summarize the significance of service grid to broadband business and illustrate the prospective research direction.
