Metropolitan Area Network
Definition and Overview
A Metropolitan Area Network (MAN) is a large network that spans a geographical area larger than a LAN but smaller than a WAN. Typically, a MAN covers an area the size of a city or a large campus, providing a high-speed network connection to a significant number of users within this geographical range.
Characteristics
A MAN is characterized by its size, which is larger than a LAN but smaller than a WAN. It is typically owned and operated by a single entity such as a government body or large corporation. The network is capable of supporting both data and voice transmission, and can be used for not only internet connectivity but also for telephony and broadcasting services.
Architecture
The architecture of a MAN is designed to provide a high-speed network connection over a large geographical area. This is achieved through the use of high-capacity backbone networks, which connect multiple LANs and other types of networks within the metropolitan area. The backbone network is typically a high-speed fiber optic network, although other types of transmission media can also be used.
Applications and Uses
A MAN is used in a variety of applications, including providing internet connectivity to businesses and residences within a metropolitan area, supporting telephony and broadcasting services, and connecting LANs in different locations within the city. It can also be used for disaster recovery, as it provides a high-speed network connection that can be used to restore data and services in the event of a disaster.
Advantages and Disadvantages
One of the main advantages of a MAN is its ability to provide a high-speed network connection over a large geographical area. This makes it ideal for businesses and other organizations that need to connect multiple locations within a city. However, the cost of setting up and maintaining a MAN can be high, and the network is also more complex to manage than a LAN.
