ATM is widely used for the backbone technology of
the world's telecommunications companies. It is used to send data,
video and voice at ultra high speeds.
The advantages of ATM are multifold. It
allows for easy integration with other technologies and provides carriers
with the ability to offer QOS (Quality Of Service). These capabilities
are a direct result of the protocols of ATM.
ATM technology uses fixed length packets,
known as cells, for transport. Information is broken into cells
at the source and reassembled at the end destination. Like most
telecommunication technologies, ATM consists of a series of layers.
The primary layer that is used for the bulk of the data transmission is
known as the adaptation layer. On top of that, there is the ATM layer
which is referred to as overhead, which directs the transmission. On
top of that is the physical layer which addresses the electrical and network
interfaces.
