Asynchronous Transfer Mode (ATM) development |
|---|
This technology from a computer networking point of view brings telephony like switching to LANs. ATM's main advantage is that it is fully scalable meaning that the same fundamental architecture applies whether you are dealing with a small in-house LAN, a campus-wide LAN involving many separate buildings, a world-wide corporate LAN involving many sites in different cities all over the world. It means that you can start small and grow gradually without loss of your investment.
With ATM you can specify capacity, source and destination locations in software, and it will allocate the bandwidth as and when needed, optimizing resource utilization. This dynamic allocation of bandwidth is a major benefit at any scale. Which is why ATM is referred to as "bandwidth on demand". meaning that idle capacity anywhere in the network can be brought to bear on a particular transmission anywhere in the local switching area.
The big benefit for corporate users is that band-width at the ATM switch, even 25Mbit/sec, is available to each connected workstation. In an Ethernet LAN the bandwidth 10Mbit to 100Mbit/sec is shared between the users currently on line, and is much lower for each individual user, about 500Kbps for the average LAN. Currently the cost of ATM hardware is prohibitive for most applications. However; there are some applications that need the performance that ATM provides and I'm sure that you are thinking of one right now.
I will be adding whitepapers and links to this page as I get the time if you need more information a good place to start is the ATM Forum, below we have provided a link as well as the phone number to the ATM Forum. Also, Bellcore offers a good computer based course on ATM for about $199. A good book to pickup is: ATM User's Guide by William A. Flanagan (from Flatiron Publishing 1-800-LIBRARY)
