互连拓朴结构是决定分布式系统体系结构的关键因素。从目前的大多数实际应用来看,动态互连网络主要被用于(MIMD)型多处理机,且开关元件的控制是集中式的。而网络型分布式计算机系统大多是由静态互连网络来实现的。如何使动态互连网络和静态互连网络结合起来,组成动静态混合互连网络,将使分布式计算机系统的结构灵活性,操作并行性和工作可靠性都有可能得到显著的提高。 Interconnection topology is the key factor that determines the architecture of a distributed system. From most practical applications at present, the dynamic interconnection network is mainly used in (MIMD) type multiprocessor, and the control of the switch components is centralized. Networked distributed computer systems are mostly implemented by static interconnection networks. How to make the dynamic interconnection network and the static interconnection network together to form a dynamic and static hybrid interconnection network will enable the distributed computer system’s structural flexibility, operational parallelism and operational reliability are likely to be significantly improved.
