ATM Network

An Introduction to ATM (Asynchronous Transfer Mode) Networks

The standards for ATM were first developed in the mid 1980s. The goal was to design a single networking strategy that could transport real-time video and audio as well as image files, text and email.

ATM (Asynchronous Transfer Mode) has been proposed as an enabling network technology to support broadband integrated services. Currently voice, data and video are transported by different networks. Voice is transported by the public telephone network, and data by a variety of packet-switched networks. Video is transported by networks based on coaxial cables, satellites and radio waves. ATM is designed to integrate all these services together.

However, ATM itself is not a complete, stand-alone networking standard; rather, ATM defines a common layer of interoperability called the ATM layer, on which various services ranging from telephony and video conferencing to TCP/IP data networking and multimedia can be delivered.

The ATM layer defines a common format used for switching and multiplexing bit streams from one end of an ATM network to another. The ATM layer then uses the hardware facilities of lower layers to deliver the bits across individual links in a network.

Technically, ATM is a cell relay, packet switching network and data link layer protocol which encodes data traffic into small fixed-sized cells (53 bytes; 48 bytes of data and 5 bytes of header information).

ATM provides data link layer services that run over Layer 1 links. This differs from other technologies based on packet-switched networks(such as IP or Ethernet), in which variable sized packets (known as frames when referencing Layer 2) are used.

ATM is a connection-oriented technology, in which a logical connection is established between the two endpoints before the actual data exchange begins.

ATM has proven very successful in the WAN scenario and numerous telecommunication providers have implemented ATM in their wide-area network cores. Many ADSL implementations also use ATM. The reason is that there will always be both brand-new and obsolescent link-layer technologies, particularly in the LAN area, not all of them fit neatly into the synchronous optical networking model for which ATM was designed.

Therefore, a protocol is needed to provide a unifying layer over both ATM and non-ATM link layers, as ATM itself cannot fit that role. IP already does that; therefore, there is often no point in implementing ATM at the network layer.

In the early 1990s, ATM was once posed to replace Ethernet and IP networks. As a result, ATM lost the battle to the "desktop".

The average ATM fee is around $2.00 and can sometimes be higher depending on the guidelines of any particular financial institution. Then one evening back in 2009 I was watching a local news channel and witnessed a man's outrage at being charged this fee for getting his own hard earned money out of the bank. If one Monday morning in San Bernardino County only 500,000 people went to the ATM 3 times that day at $2.00 per transaction, that would total $3 million dollars! So what is a Network Marketing ATM'r? It's actually a term I created to describe a particular category of people who do this business. These people for various reasons seem to have trouble getting out of the nickel and dime earning phase of their opportunity. The fact is, these people unfortunately work too hard and regardless of who's at fault they're working wrong.

Think about it, after travel expenses to meetings, auto ships (If there are any), supply costs, phone bills, downline babysitting, poor recruiting, people leaving your dowline for another opportunity and conference calls at dinner time, frustration can set in. Now remember, these are just the ATM'rs! For the guy on top, it's worth it to keep those people holding on to dreams that will never come true if they don't make changes or adjustments! (The upline Banker) Don't get me wrong, the upline is happy if you make your way to one of the higher positions in your opportunity because they benefit big from that! If not, find out if this is really the business opportunity that they should be in because if they don't believe in what they're doing, the prospect won't either. Too many times the big money makers preach to the ATM'rs don't quit, you're one person away from recruiting a superstar, don't give in, keep talking to people, don't let anyone tell you this business isn't right for you, keep coming to the trainings, stay plugged in!
