当异步传输模式(ATM)领头向主流技术方向进军时,ATM设计界必须面对若干技术与战略上的挑战、其中的许多方面都涉及交换机开关装置(switch-fabrie)设计与实现问题.此外还涉及充实细节和加紧制订使网络之间得以无缝连接和通信量得以控制的协议等问题.首先考查一下技术问题.目前有着几个通用型交换机开关装置设计技术,其中的大多数可就其体系结构类型的不同加以归类.包括格树(banyan)型和缓存榕树型开关结构,纵横制和交叉点开关结构,以及时间分割型开关结构.但是,不管是什么样的开关结构,许多别的问题都应予以解决.
When Asynchronous Transfer Mode (ATM) leads into mainstream technology, the ATM design community has to face a number of technical and strategic challenges, many of which involve the design and implementation of switch-fab switches. Involving more details and stepping up efforts to establish protocols that allow for seamless connectivity between networks and control of traffic, etc. First, look at the technical issues. There are several general switch switch device design techniques currently available, most of which are available on their systems Including the banyan and cache banyan-type switch structures, crossbar and cross-point switch structures, and time-division switch structures. However, no matter what kind of switch structure, many others The problems should be solved.
