What is a wide area network (WAN)?

A wide area network or WAN is a computer network covering a wide geographical area, involving a vast array of computers. This is different from local area networks (LANs) that are usually limited to a room, building or campus. The most well-known example of a WAN is the Internet.

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. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are most often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Network protocols including TCP/IP deliver transport and addressing functions.

What is VPN and why do I need it?

A virtual private network (VPN) is a private communications network usually used within a company, or by several different companies or organizations, to communicate over a public network. VPN message traffic is carried on public networking infrastructure (e.g. the Internet) using standard protocols.

Why should you consider a VPN?

A well-designed VPN can provide great benefits for an organization. It can:

• Extend geographic connectivity.
• Improve security where data lines have not been ciphered.
• Reduce operational costs versus traditional WAN.
• Reduce transit time and transportation costs for remote users.
• Simplify network topology in certain scenarios.
• Provide global networking opportunities.
• Provide telecommuter support.
• Provide broadband networking compatibility.
• Provide faster ROI (return on investment) than traditional carrier leased/owned WAN lines.
• Show a good economy of scale.
