The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
Administration typically involves collecting performance stats, accounting data for the purpose of billing, capacity planning using Usage data, and maintaining system reliability. It can also involve maintaining the service databases which are used to determine periodic billing.
Wide area networks (WAN) Metropolitan area networks (MAN) Local area networks (LAN) There are three features that differentiate MANs from LANs or WANs: The area of the network size is between LANs and WANs. The MAN will have a physical area between 5 and 50 km in diameter. [2] MANs do not generally belong to a single organization.
A WAN often makes use of transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI model: the physical layer, the data link layer , and the network layer .
LANs can maintain connections with other LANs via leased lines, leased services, or across the Internet using virtual private network technologies. Depending on how the connections are established and secured, and the distance involved, such linked LANs may also be classified as a metropolitan area network (MAN) or a wide area network (WAN).

To calculate the correct dimensioning to comply with the above rule, the planner must take on-going measurements of the network’s traffic, and continuously maintain and upgrade resources to meet the changing requirements. [1] [2] Another reason for overprovisioning is to make sure that traffic can be rerouted in case a failure occurs in the ...
