Beginner S Guide To Asynchronous Transfer Mode Atm
Asynchronous Transfer Mode (ATM) is a high-speed networking standard that supports voice, video, and data communications. It also improves the utilization and quality of service (QoS) of high-traffic networks. Internet service providers use ATM on private long-distance networks. ATM operates at the data link layer—Layer 2 in the OSI model—over either fiber or twisted-pair cable. Although it’s fading in favor of the next-generation network (NGN), the ATM protocol is critical to the Synchronous Optical Network (SONET) that forms the backbone of many internet service providers, the public switched telephone network (PSTN), and the Integrated Services Digital Network (ISDN)....
