近两年推出的ATM信元交换代表着90年代中期的网络技术。在ATM论坛、国际电信联盟ITU等组织所制定的规程指导下,它已接近成熟。以ATM信元为基础的交换技术和传输技术可以提供高速的信息传输和可调节的使用带宽,具有极好的网络性能。并且可以广泛应用于桌面系统网络、主干网和广域网中。ATM集成了混合信息(图象、视频和语音)的同步传输与传统的数据传输。它除具备交换式局域网的全部优点外,还有以下优点:
The ATM cell exchange introduced in the past two years represents the network technology of the mid-1990s. It is close to maturity under the guidance of the rules set by the ATM Forum, the International Telecommunication Union ITU and other organizations. Exchange and transmission technology based on ATM cell can offer high-speed information transmission and adjustable use bandwidth, have excellent network performance. And can be widely used in desktop system network, backbone and WAN. ATM integrates the synchronous transmission of mixed information (image, video and voice) with traditional data transmission. It has all the advantages of switching LAN, but also has the following advantages:
