Abstract

This study aims to explain the unfamiliar term of “Asynchronous Transfer Mode” and its benefits in company. It is safe to say that companies nowadays depends on technology. And one of it is the asynchronous transfer mode that is a “special” network. This ATM is like a tool to boost the internet speed. But ATM can only be used to boost the internet speed if connected to some kind of signals like frame relay or SONET. ATM is also service-independent. All services (data, pictures, sound, etc) can be transmitted through ATM by setting some types of ATM Adaptation Layer (AAL). AAL. AAL changes the original format of information into the ATM format, so that the information can be trasmitted. ATM works by dismembering, then recombining the varying types of information (voice, video, data, etc) in a 53-byte cell format through the same physical channel. That kind of process named statistical multiplexing. In short, ATM is a double-layered technology, that can be used by anyone, and also is a public network as well as internet, with a neatly managed addressing system that every device in a network can has a unique identity. ATM has such benefits as supporting services for all types of applications currently available and application developments in the future, providing very high utilization of network resources, reducing switching complexity, and so on. With that kind of benefits, ATM is a very useful tools for companies.
