摘要
国内首台ATM(异步转送方式)交换机BTC9500的研制于1995年完成,并配合国内宽带试验网络的建设,进行了大量的组网试验、设计改进和发展工作。目前,该设备已经由国内最大的电信设备制造商之一上海贝尔公司生产销售,并且用于装备中国电信宽带骨干网的全部核心节点。根据组网实践中发现的问题,提出了在同一个交换结构内同时实现ATM信元交换和IP数据报交换的方案,并在BTC9500中予以实现,达到了大大节省设备、简化网络和提高网络速度的多重目的,将研究范围逐渐拓宽到更大的宽带通信领域,提出了对于新一代电信网络发展的一些看法。
The design and implementation of the first ATM Switching system of China(Named BTC9500)was started in 1993.The prototype was completed in 1995.Much field trial has been done since then,with the development of China’s broadband network.The prototype has been improved as well.\;BTC9500 was then transferred to Shanghai Bell for manufacturing and marketing.It has been used in China’s nation wide broadband backbones.It was named China’s Important New Product,and won prizes from both the Nation and the Ministry of Information Industry.\;The research on the BTC9500 networking unveiled the disadvantage of ATM switch/IP router combination.The scheme of switching both ATM cells and IP datagram within a single switching fabric was proposed and implemented in BTC9500.The cost is reduced.The network is simplified.A model of new generation platform that supports multi\|service switching is given.\;Based on the experience,some viewpoints on the development of the new generation network are proposed in this paper.
