What is ATM protocol in networking?

ATM stands for Asynchronous Transfer Mode. It is a switching technique that uses time division multiplexing (TDM) for data communications. ATM networks are connection oriented networks for cell relay that supports voice, video and data communications.

What protocol do ATMs use?

Common lower-level layer communication protocols used by ATMs to communicate back to the bank include SNA over SDLC, TC500 over Async, X. 25, and TCP/IP over Ethernet.

Which type of network is used in ATM?

ATM provides functionality that uses features of circuit switching and packet switching networks. It uses asynchronous time-division multiplexing, and encodes data into small, fixed-sized network packets.

Is ATM a WAN?

Asynchronous Transfer Mode (ATM) is a WAN technology that uses fixed length cells. ATM cells are 53 bytes long, with a 5-byte header and 48-byte data portion. ATM allows reliable network throughput compared to Ethernet. In contrast, all ATM cells are 53 bytes.

What is an ATM protocol?

The ATM protocol. In the ATM protocol domain the socket interface provides an application with direct access to an ATM virtual connection. The ATM protocol is offered as a new address family, AF_ATM. Each Protocol Data Unit (PDU) to be transmitted over the connection is handed directly to the ATM adaptation layer for segmentation…

What does ATM mean on a computer?

atm – Computer Definition. A fast-packet, connection-oriented, cell-switching technology for broadband signals.ATM was an outgrowth of the ITU-T development efforts towards broadband integrated services digital network (B- ISDN ).

What is ATM technology?

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.

What is an ATM connection?

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. Individually, a cell is processed asynchronously relative to other related cells…
