Introduction to ATM Networks
ATM was developed because of developing trends in the networking field. The most important parameter is the emergence of a large number of communication services with different, sometimes yet unknown requirements. In this information age, customers are requesting an ever increasing number of new services. The most famous communication services to appear in the future are HDTV(High Definition TV), video conferencing, high speed data transfer, videophone, video library, home education and video on demand.
This large span of requirements introduces the need for one universal network which is flexible enough to provide all of these services in the same way. Two other parameters are the fast evolution of the semi - conductor and optical technology and the evolution in system concept ideas - the shift of superfluous transport functions to the edge of the network. Both the need for a flexible network and the progress in technology and system concepts led to the definition of the Asynchronous Transfer Mode (ATM) principle.
ATM is a high-speed, packet-switching technique that uses short fixed length packets called cells. Fixed length cells simplify the design of an ATM switch at the high switching speeds involved. The selection of a short fixed length cell reduces the delay and most significantly the jitter (variance of delay) for delay-sensitive services such as voice and video. ATM is capable of supporting a wide range of…………….So on ..........(download any of the following links to get complete paper presentation in word document)
