摘　　要：主要研究了可重构MPMS交换结构的通用架构。根据交换/缓存级的不同,架构中功能实体和连接链路分为多个功能子集和连接链路子集,并根据可重构MPMS交换结构的缓存结构进行了分类。运用有向图理论,构建了可重构MPMS交换结构的DGM模型,研究模型中顶点子集的均衡性与竞争性,讨论了DGM模型的交换路径分布特性。文章为可重构MPMS分组交换技术的深入研究提供了理论基础。The universal architecture of the MPMS switching fabric is studied in this paper. Accord- ing to different switching and buffering stages, functional entities and interconnection links are divid- ed into multiple functional sub-sets and multiple link sub-sets, and the configurable MPMS switching fabric is classified based on its buffering methods. What＇ s more, the DGM model of the MPMS switching fabric is built based on the directed graph theory. In the DGM model, the properties of balance and competition are studied, and then studied the distributed property of switching path in the DGM model. The theoretical basis is provided for the configurable MPMS switching fabric.
