Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and data link layer protocol which encodes data traffic into small (53 octets; 48 octets of data and 5 octets of header information) fixed-sized cells. ATM provides data link layer services that run over Layer 1 links. This differs from other technologies based on packet-switched networks (such as the Internet Protocol or Ethernet), in which variable sized packets (known as frames when referencing Layer 2) are used. ATM is a connection-oriented technology, in which a logical connection is established between the two endpoints before the actual data exchange begins.

The standards for ATM were first developed in the mid 1980s. The goal was to design a single networking strategy that could transport real-time video and audio as well as image files, text and email. Two groups, the International Telecommunications Union and the ATM Forum were involved in the creation of the standards. ATM has been used primarily with telephone and IP networks.

      Asynchronous Transfer Mode (ATM) Fundamentals

      Asynchronous transfer mode (ATM) is a high-performance, cell-oriented switching and multiplexing technology that utilizes fixed-length packets to carry different types of traffic. ATM is a technology that will enable carriers to capitalize on a number of revenue opportunities through multiple ATM classes of services; high-speed local-area network (LAN) interconnection . . .

      Asynchronous Transfer Mode Overview

      Asynchronous Transfer Mode (ATM) is a technology that has the potential of revolutionizing data communications and telecommunications. Based on the emerging standards for Broadband Integrated Services Digital Networks (B-ISDN), ATM offers the economically sound 'bandwidth on demand' features of packet-switching technology at the high speeds required for today's LAN and WAN networks -- and tomorrow's.

      Digital Subscriber Line (DSL) and the Evolution of Asynchronous Transfer Mode (ATM)

      Overview Deregulation, together with increasing consumer and business demand for high bandwidth services, has led to increased competition among service providers. This increase in competition has, in turn, presented providers with an important set of business challenges. With increased competition, it becomes critical for providers to market and press for innovative services. Providers must move up the value chain in service delivery,...
