A Guide To Asynchronous Transfer Mode


By: George Yee


The asynchronous transfer mode, sometimes also known as ATM, is a transferring technique based on cell. The advent of ATM has resulted in a revolution in the way various communication systems function these days and is closely linked with networking. This comprises loads of terrific features and is compatible with both local area and wide area network connections.

Now many of us might be acquainted with the term "ATM," but we can barely make out anything with reference to its functionality or the way it works. Asynchronous transfer mode might be described as a characteristically cell based transferring system that exclusively takes advantage of multiplexing by asynchronous division of time. This makes it possible to encode the specific information into specific sized cells and cell relays and offer an exclusive data linkage layer service that expressly rely on an OSI Layer 1 physical connection. But, more often than not, people mistake asynchronous transfer mode for a packet switched system such as the IP or Ethernet, which basically rely on small packets of different sizes for transfer of data.

In general, it combines the traits of both local area and wide area networking. This means that it can be utilized in a switched circuit mode in addition to the packet switched system, which might double up as an ideal way of transfer for a wide variety of data. Asynchronous transfer mode is also really appropriate for an instantaneous and synchronized media transfer. The system that is mainly utilized in this particular method of data transport largely relies on the connection. Thus, it links the two points with any virtual circuit with no trouble even before the transfer of data begins.

Asynchronous transfer mode technology can be utilized without difficulty in both local and wide area network connections. This has many unique features and applications. It can be possibly used to provide a data transfer rate of around 2.5 GB/s which helps in effortless running of distributed functions on high bandwidths. This is mostly helpful in video streaming methods used for video conferencing.

The asynchronous transfer mode offers better transfer seeds for LAN or WAN links easily by merely enabling the distribution of high powered applications. It draws on the essential systems to alternate between various switching systems. This makes it especially suitable for such distributed applications that usually need constant bit rate traffic. This generally makes use of virtual networks to gain more traffic.

In conclusion, asynchronous transfer mode is a mode of data transfer. This is especially useful for applications requiring a high bandwidth.
