非同步傳輸模式ATM綱路具有保證服務品質(Quality of Service; QoS)安全性佳及流量控管能力,其架構在同步光纖綱路或同步數位階層(ATM over SONET/SDH)上所形成的寬頻整合服務數位綱路(B-ISDN),普遍被認爲是當今高速綱路的骨幹,而ATM能夠將語音、數據、影像及多媒體等各種型態整合在一起,可以說是目前最佳的資訊交換網路。
ATM (Asynchronous Transfer Mode) possesses the capability of the guarantee of quality of service, optimized security, and flow control. ATM over SONET/SDH (ATM over Synchronous Optical Network/Synchronous Digital Hierarchy) that forms Broadband Integrated Service Digital Network (B-ISDN) has been considered the backbone of modern high-speed network. Furthermore, ATM integrates voice, data, video, and multimedia and is the best switch network of information presently.
