ASYNCHRONOUS TRANSFER MODE

Presented By :- Rishabh

Introduction to ATM

ATM is a cell-switching and multiplexing technology that combines the benefits of circuit switching with those of packet switching .

Circuit Switching is specific path set up for each connection e.g. telephone networks .

Packet Switching means no predefined paths e.g. traditional LAN.

ATM Switching is Hybrid of packet and circuuit switching

Infrastructure

Backbone LAN

LAN (Asynchrounous Transfer Mode)

LANs 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; >>voice, video, and future multimedia applications in business markets in the short term and >>in community and residential markets in the longer term.
