基于对等网络的全球信息网格服务发现机制研究

Research on Service Discovery Protocol of Global Information Grid Based on Peer-to-Peer Network

全球信息网格采用面向服务的架构提高系统的可重用性、柔性设计能力以及按需快速构建能力。这些优势的充分发挥需要快速及时发现各类可用的数据和服务。该文提出了两种扩展性很好的分布式服务发现机制:面向完全自治UDDI注册中心的非结构化UDDI对等网络和面向协同UDDI注册中心的结构化UDDI对等网络。

Global information grid（GIG） employs service oriented architectures（SOA）. The use of SOA enables loosely coupled applications, service reuse, flexibility in system design and the ability to rapidly assemble applications/solutions in an ad-hoc fashion. The key to all of this is the ability to discover relevant data and services in a timely fashion. This paper presents two distributed and scale-well approaches for fully autonomous registries and cooperative registries to overcome the disadvantage of traditional registries. In other words, it provides an unstructured peer-to-peer network for fully autonomous registries and a structured peer-to-peer network for cooperative registries.
