一般的网络环境中并不需要ATM所能提供的独到的性能,但对那些早期的ATM用户来说,ATM却是最佳的,也是仅有的解决方案。这些用户一般是在面临某个特定的应用需求时才采用ATM,而这些需求一般可分为以下三种:园区网或WAN主干网存在带宽瓶颈;新的用户应用系统需要更高带宽或交互式多媒体支持;若不采用ATM网络,建设多个网络造价太高。
The typical network environment does not require the unique capabilities ATM offers, but for those early ATM users, ATM is the best and the only solution. These users typically adopt ATM only when confronted with a specific application requirement, which can be generally divided into three types: a bandwidth bottleneck in a campus network or a WAN backbone; a new user application system requiring higher bandwidth or an interactive Multimedia support; if you do not use the ATM network, building multiple networks is too costly.
