What is ATM?

• ATM stands for Asynchronous Transfer Mode (not Automated Teller Machine!).

• ATM is an emerging standard for high speed transfer of integrated media types -- voice, video, and data -- all on the same communication medium.

• The key benefits of ATM include:
  
  • Efficient use of network bandwidth
  • Scalability (both in terms of # of users, and bandwidth)
  • Low latency and latency variation
  • Transparency to Existing Applications
  • Integrated Services
  • Internetworking with Existing WANs
