Atm

  1. 1. ATM 工教一 49871029 郭筑亞
  2. 2. ATM Asynchronous Transfer Mode is a cell-based switching technique that uses asynchronous time division multiplexing
  3. 3. ATM It encodes data into small fixed-sized cells ( cell relay ) and provides data link layer services that run over OSI Layer 1 physical links.
  4. 4. ATM 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.
  5. 5. ATM ATM exposes properties from both circuit switched and small packet switched networking, making it suitable for wide area data networking as well as real-time media transport.
  6. 6. ATM ATM uses a connection-oriented model and establishes a virtual circuit between two endpoints before the actual data exchange begins.
  7. 7. ATM ATM is a core protocol used over the SONET/SDH backbone of the Integrated Services Digital Network .
