Research details of the THREE (3) WAN Technologies

1. MPLS

- It stands for Multiprotocol Label Switching.

- It is expensive

- a way to make sure reliable connections for real-time applications

How it works?

- carry data and voice, and can be used to simplify WAN routing

-Example

2. Frame Relay

- It is high performance of WAN protocol.

- Today, it is used for variety of other network interfaces.

How it works?

- FR use Virtual Circuits (VC) to set up the connections over the WAN.

- Examples: Packet Switch Technology.

3. ATM

- It is stands for Asynchronous Transfer Mode

- It is a switching technique for telecommunication networks 

- It use asynchronous time division multiplexing and it encodes data into small

How it work?

- Once a connection is set up, the ATM network will provide end-to-end quality of service to the end users.

- The routing information is carried in the header of each cell

- Cells are reassembled into voice, video, image, or data at the destination.

- Examples
