近几年来,从政府到企业,从大城市到小城镇,兴起了一浪一浪的网络建设高潮。今天是100M以太网,明天就是ATM;今天是局部网,明天就是Internet。如此快的技术更新,真是令人目不暇接。 国外计算机网络的发展,总是以应用为驱动的。PC装机量的增长,自然产生了NetWare;交换技术的出现是因为传统路由技术已成为网络的瓶颈;Internet主干网的带宽由最初的1.5M增至45M,接着很快扩容为622M是因为数据流量激增的结果。
In recent years, from the government to enterprises, from big cities to small towns, there has been a wave of waves of network construction climax. Today is 100M Ethernet, tomorrow is ATM; Today is the local network, tomorrow is the Internet. So fast technology updates, it is dizzying. The development of foreign computer networks is always application-driven. The growth of PC installed capacity naturally resulted in NetWare. The emergence of switching technology is due to the fact that the traditional routing technology has become the bottleneck of the network. The bandwidth of the Internet backbone has been increased from the original 1.5M to 45M and then rapidly expanded to 622M because of data traffic The surge of results.
