基于内容的发布/订阅拓扑模型设计和自配置协议研究

Design of Topology Model and Research on Self-Configuration in Content-Based Publish/Subscribe Systems

拓扑结构和自配置特性是实现大规模基于内容的发布/订阅系统的关键问题之一,决定了系统的可扩展性。为了提高发布/订阅系统性能,引入了空间划分的概念,设计了一个具有空间划分的层次拓扑模型。针对节点或者链路失效所带来的网络分割问题,本文在静态拓扑模型的基础上提出了一个自配置协议,提高了系统的可靠性和扩展性。

Topology structure and self-configuration characteristic are two key issues in the area of large-scale content-based publish/subscribe systems, guarantee scalability of system. To raise the performance of Publish/Subscribe Systems, this paper introduces the concept of partition-space, designs a hierarchical topology model of partition-space. To solve the network reconfiguration problem for the node or link failure, this paper introduces proposes a Self-Configuration protocol.
