ATM is a1connection-oriented technology, in which a connection is established between the twoendpoints before the actual data exchange provides a highly complex technology, with features intended for applicationsranging from global telco networks to private local area computer networks.

networks, rather than their IP networks into the voice infrastructure. Many technically sound ideas from ATM were adopted by MPLS, a generic layer 2 packet switching protocol. ATM remains widely deployed, and is used as a multiplexing service in DSL networks, where its compromises fit DSL’s low-data-rate needs well. In turn, DSL
