近25年来,交换与路由技术得到了迅猛发展。而目前,这两种基本联网技术某种程度上似乎都已稳定下来。新一代局域网互联网络将由多种交换机与路由器构成,并以帧技术如以太网为基础。公共广域网也将由多种设备组成,但主要用于管理基于信元的ATM。那么路由与交换技术是否已经发展成熟了呢?绝非如此。对信元和帧的激烈争论仍将继续进行下去。另外,这两种基本的联网技术正在使协议堆栈下断增加。传统的路由技术仅以目的主机编号为基础。将来,它还
The past 25 years, exchange and routing technology has been rapid development. At the moment, both of these basic networking technologies seem to have stabilized to some degree. Next-generation LAN The Internet will consist of a variety of switches and routers and will be based on frame technologies such as Ethernet. The public WAN will also be made up of a variety of devices, but will primarily be used to manage cell-based ATMs. Then routing and switching technology has matured? This is by no means the case. The heated debate over cells and frames will continue. In addition, these two basic networking technologies are breaking down the protocol stack. Traditional routing techniques are based on the destination host number only. In the future, it also
