使用简单地址管理方式基于共享存储器的ATM交换结构的原理与实现

DESIGN AND IMPLEMENTATION OF A SHARED BUFFER BASED ATM SWITCHING ELEMENT WITH SIMPLE ADDRESS MANAGEMENT

本文提出了一种使用简单地址管理方式基于共享存储器的 (Share Buffer based Simple Address Management,SBSAM) ATM交换结构 ,它使用简单的计数器管理共享存储器的地址空间 ,在保证控制与实现简单的基础上 ,实现了多播 (multicast) ,提供了不同信元优先级 ,队列调度 ,反压机制等功能 ,在一定程度上保证了 Qo S.同时作为一个可叠加的交换结构 ,还有易于扩展 ,方便多级互联 。

This paper proposed a shared buffer based ATM switching element with simple address management(SBSAM). It simply uses a counter to manage the address space. Besides easy to control and implement, it realizes multicast, multiple cell priorities, queue scheduling, back pressure mechanism, etc. It guarantees QoS to a great extent. At the same time, act as a foldable switching element, it also has the virtue of easy to expand, convenient to interconnect, simple to realize distributed control.
