  Introduction to WAN Technologies
A WAN is a data communications network that covers a relatively broad geographic area and that often uses transmission facilities provided by common carriers, such as telephone companies.
WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer.
WANs use numerous types of devices that are specific to WAN environments.

  Wide area network - Wikipedia, the free encyclopedia
A wide area network or WAN is a computer network covering a wide geographical area, involving a vast array of computers.
WANs are used to connect local area networks (LANs) together, so that users and computers in one location can communicate with users and computers in other locations.
X.25 was an important early WAN protocol, and is often considered to be the "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.

 WAN - Wide Area Network   (Site not responding. Last check: 2007-10-18)
WANs are built to provide communication solutions for organizations or people who need to exchange digital information between two distant places (in one country or in two different countries).
WANs enable an organization to have one integral network between all its departments and offices, even if they are not all in the same building or city, providing communication between the organization and the rest of the world.
The WAN, has come a long way since the days of analog leased lines and is taking more and more tasks from the old separated networks into one integral network which enables good communication for any type of data or application.

 WAN Topologies
A WAN peer-to-peer topology is similar to peer-to-peer communications on a LAN in that each site depends on every other site in the network to transmit and receive its traffic.
The WAN peer-to-peer topology is often the best option for organizations with only a few sites and the capability to use dedicated circuits--that is, continuously available communications channels between two access points that are leased from a telecommunications provider, such as an ISP.
Tiered WAN topologies are similar to the hierarchical hybrid topologies used with LANs.

WAN emulation is a simple idea: slow down the local network so that it will behave like a WAN -- creating a test bed where network performance closely resembles the performance of the user's WAN.
WAN emulation allows for the controlled degradation of the Local Area Network (LAN) in a test bed environment, morphing it into a controlled and repeatable WAN environment.
WAN emulators can be used for testing and evaluating a wide range of IP-based technologies, the most obvious one being IP telephony.

 RFC 1634 (rfc1634) - Novell IPX Over Various WAN Media (IPXWAN)
IPX WAN Protocol Description After the underlying data link connection is established as described in the preceding media dependant description, the IPXWAN protocol is activated to exchange identities and determine certain operational charactaristics of the link.
If a router wishes to provide WAN Client access without supporting other WAN routing types, a potential problem arises since a router and WAN client would both just be sending a single Routing Type option indicating the use of WAN Client.
The router MUST additionally include one (or more) of the defined routing types (like WAN RIP) with the WAccept option set to NO. This is so that a workstation may detect that this is actually a router sending the Timer Request and not just another workstation trying to call a workstation.
