Introduction to WAN

When an enterprise grows to include branch offices, e-commerce services, or global operations, a single LAN network is no longer sufficient to meet its business requirements. Wide-area network (WAN) access has become essential for larger businesses today.

There are a variety of WAN technologies to meet the different needs of businesses and many ways to scale the network. Adding WAN access introduces other considerations, such as network security and address management. Consequently, designing a WAN and choosing the correct carrier network services is not a simple matter.


What is a WAN?
A WAN is a data communications network that operates beyond the geographic scope of a LAN.

WANs are different from LANs in several ways. While a LAN connects computers, peripherals, and other devices in a single building or other small geographic area, a WAN allows the transmission of data across greater geographic distances. In addition, an enterprise must subscribe to a WAN service provider to use WAN carrier network services. LANs are typically owned by the company or organization that uses them.

WANs use facilities provided by a service provider, or carrier, such as a telephone or cable company, to connect the locations of an organization to each other, to locations of other organizations, to external services, and to remote users.

WANs generally carry a variety of traffic types, such as voice, data, and video.
