Asynchronous transfer mode (ATM)

In this article we will discuss Asynchronous transfer mode (ATM), will make brief discussion on Asynchronous transfer mode (ATM), In last article we discuss about Wide Area Network (WAN).

Asynchronous Transfer Mode is, according to the ATM Forum, “a telecommunications concept defined by ANSI and ITU standards for carriage of a complete range of user traffic, including voice, data, and video signals”. The ATM cell is the basic unit of information transfer in the B-ISDN ATM communication. The cell is comprised of 53 bytes. Five of the bytes make up the header field and the remaining 48 bytes form the user information field.

Asynchronous transfer mode (ATM) is a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells. This is different from Ethernet or internet, which use variable packet sizes for data or frames.

ATM provides functionality that is similar to both circuit switching and packet switching networksATM uses asynchronous time-division multiplexing, and encodes data into small, fixed-sized packets (ISO-OSIframes) called cells. ATM (asynchronous transfer mode) is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology.
