What is Asynchronous Transfer Mode (ATM)?
Asynchronous transfer mode (ATM) is a switching technology that facilitates the movement of data from one point to another. It is one of the preferred technologies because of its efficiency of use, especially with different hardware components. Unlike other types of technology, the speed and efficiency used in asynchronous transfer mode makes it one of the most common network protocol standards in use today. The main advantage of asynchronous transfer mode technology is the ability to transfer many different types of data at the same time. This is because all bandwidth is utilized, as long as it is available. Other types of technologies will often not allow all the bandwidth to be used once a particular function is started. Therefore, it makes for a very efficient way to transfer video files, pictures, e-mail and even live streaming audio and video. Encoding data in asynchronous transfer mode is remarkably consistent, with each cell being 53 bytes in length. This helps during the proce
Asynchronous Transfer Mode (ATM) is a transfer protocol with the following characteristics: • It is scalable and flexible. It can support megabit-to-gigabit transfer speeds and is not tied to a specific physical medium. • It efficiently transmits video, audio, and data through the implementation of several adaptation layers. • Bandwidth can be allocated as needed, lessening the impact on and by high-bandwidth users. • It transmits data in fixed-length packets, called cells, each of which is 53 bytes long, containing 48 bytes of payload and 5 bytes of header. • It is asynchronous in the sense that although cells are relayed synchronously, particular users need not send data at regular intervals. • It is connection oriented, using a virtual circuit to transmit cells that share the same source and destination over the same route. For more information, visit the IP/MPLS Forum site, a non-profit organization of ATM developers. Note: ATM is also an acronym for “Adobe Type Manager”.

What is Asynchronous Transfer Mode (ATM)? Asynchronous Transfer Mode (ATM) is a connection oriented data transmission protocol based on groups of fixed length cells. These cells provide high speed transmission of a wide range of computer traffic, including voice, data, and video. In addition, ATM technology allows you to set up a number of virtual connections to carry cells from different applications over the same physical connection. ATM edge-devices, such as a SuperStack II Switch 2000 TR with an ATM Module provide the connection. The Segmentation and Reassembly (SAR) sub-layer in an edge-device segments the original Token Ring frames and converts them into ATM cells for transmission. ATM Switches switc
