ATM strategy

Well in today’s world everything is moving fast we are all learning and re-learning new things over and over. Before I start I wanted to ask the class why do they think emerging communication technologies are here? Basically why do we need to communicate them?

Well Uyless Black, a lecturer on communications technologies says

Today emerging technologies are here to overcome the deficiencies of the current technologies. Each new technology must meet the needs of applications

What he’s basically saying is we don’t need faster computers, we don’t need faster applications WE HAVE THEM and they are advancing in a millisecond rate, we need better communications between systems to be more accurate between Wide and Local area networks.

We choose Asynchronous Transfer Mode not because it’s a any protocol it’s the mother of all protocols and you will learn why in just a few minutes.

Just to define some how some of the information is handled before it actually transmits data, PMD synchronizes the transmission and reception of the connection and maintains continuous flow and TC allows devices to locate cells within a stream of bits.

Now I know what you guys are all thinking, How then this information directed…well first in front of the information you want to send there is header which contains all specifications about the load that will come after it, this is similar to an envelope, What do you need for an envelop? A Stamp, Mail Address and an optional Return address, you might even need two stamps!

So when your first going to send out your letter you put the right information on the top then drop it off to the closest mail box, after the header there is the pay load and we can see this similar to the mail carrier that carriers all ur letters and delivers them to the right destination, and like your envelope when they reach their destination the Name on the envelope is the person you want to be reading your message. That is similar to what the payload incorporates.

Now your thinking I got the envelop I wrote the letter but then who’s going to carrier my letter to my friend! Well actually you don’t care, but for ATM and as a Technician you must know which device you’re going to hook up

You basically use Switches/Bridges, they are two devices but are usually now embedded into one and perform functions what is inside the header and payload. Now we know how its directed and how its carried, now how is it handled?

Well inside each header there are bits called the VC and VP each of these are similar to telephone numbers but only regarded to each switch/bridge/router locally and no significance when transmitted except during the process of the switch where it translates that number to the right path in the opposing network.
