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 . . .

      A Survey on ATM Security

      This paper discusses the ATM security problems, requirements, implementation issues and challenges. Most recent ATM Forum contributions about security and two recent results, drafts about ATM Security Framework and Phase I Specification are also discussed in this paper.

      CISCO ATM Overview

      ATM is based on the efforts of the ITU-T Broadband Integrated Services Digital Network (BISDN) standard. It was originally conceived as a high-speed transfer technology for voice, video, and data over public networks. The ATM Forum extended the ITU-T's vision of ATM for use over public and private networks.

      ATM Portal

      Some of the old articles on communications technology that I've saved come in handy - not because there isn't more up-to-date literature, but because they remind me why, after almost thirty years in the field, I've become such a skeptic. I've seen so many promises broken. In the 1990's the communications gurus were certain that ATM was the technology that would bring about network convergence - voice and data, end-to-end, on one network...

      Asynchronous Transfer Mode Tutorial

      In this tutorial we present an overview of ATM and Gigabit Networks. We begin with an overview of High Speed Netwroks and their applications. Next we examine the details of the ATM protocols and formats. We also look at the ATM-adaptation layers (AAL) and the manner in which ATM cells are actually packaged for transmission acroos the user-network interface.

      Asynchronous Transfer Mode(ATM) Tutorial

      Aynchronous Transfer Mode (ATM) has been accepted universally as the transfer mode of choice for Broadband Integrated Services Digital Networks(BISDN). ATM can handle any kind of information i.e. voice, data, image, text and video in an integrated manner. ATM provides a good bandwidth flexibility and can be used efficiently from desktop computers to local area and wide area networks. ATM is a connection- oriented packet switching technique...

      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,...

Mark Twain quote for the day:

Now, isn't imagination a precious thing? It peoples the earth with all manner of wonders, strange beasts and birds, angels, cherubim and seraphim. And it has to be exercised. No child should be permitted to grow up without exercise for imagination. It enriches life for him. It makes things wonderful and beautiful.
- speech in Elmira, April 1907 (reprinted in Mark Twain in Elmira by Jerome & Wisbey)
