Common WAN Technology

Some of the useful and common WAN technologies i have listed below:

1.ATM- Asynchronous Transfer Mode

* Data is divided into small, fixed packets called cells.
* Each cell is 53 octets:
* 5 octets for header info
* 48 octets for data transmission
* ATM originally designed for simultaneous transmission of data, voice, and video.
* Quality of Service (QOS) is adjustable with bandwidth needs: higher for video, lower for data and video.

2.Frame Relay

* Data is divided into small, variable sized cells, up to 16,000 octets!
* Up to 1.544Mbps transmission rate.
* Uses “cloud” concept – shared bandwidth with other connections

3. SONET
