Networking fundamentals with Metropolitan Area Network (MAN)

What do you need to know about MAN networking?

Computer networks have evolved greatly over the years. In this modern-day and age, there are multiple types of networks like Metropolitan Area Network that satisfy specific requirements for millions of various users.

What’s a Metropolitan Area Network?

A Metropolitan Area Network is a computer network based in a metropolitan or city area, through a connection of multiple LAN. It can access by point to point connections. By combining smaller LAN networks, MANs have the ability to extend to a geographical area of 5 to 50 km. It is sufficient for the network requirements of a city. This interconnection of networks across the city may also end up facilitating connections to WAN.

Use of MAN technology

MANs are particularly useful for the purpose of sharing resources specific to regions, assisting in the quicker and segmented flow of data and information. Furthermore, MANs can connect multiple computers and networks to serve as an Internet Service Provider. This is because of which the internet service provided by a telephone company falls under the category of a MAN connection. A Metropolitan Area Network is smaller than the area covered through WANs. It is much bigger than the connectivity capabilities of a LAN.

Working methodology of MAN

The working mechanism of a MAN is quite similar to that of an Internet Service Provider. However, it is not owned by a single organization. A MAN delivers a joint and shared network connection to all of its users based on a data link layer. This data link layer is classified as a Layer 2 of the OSI model. It is also known as Open Systems Interconnection.

The primary goal of a MAN is to establish a connection between geographically separated LANs. It means that a MAN seeks to form a communication link between two independent LAN nodes. It establishes using optical fibers cables. In order to refresh memory, a switch is responsible for filtering data inflowing in the shape of frames. The switch lies as one of the fundamental components as it is actively responsible for dual tasks. At one end, it filters data and on the other end, it manages the connection.

Types of MAN technologies


Fiber Distribution data interface is a standard for data transfer in context to a LAN and it can assist in transmitting the data of thousands of users. It uses optical fiber for its primary infrastructure; hence the name fiber distributed data interface.


Switched multi-megabit data service allows the transfer of data through a connectionless service. It is the state of data transfer when the information and data stores in the head and then it reaches

its specific destination in an independent manner.


Asynchronous Transfer Mode is the most frequently used MAN technology. However, ATM is a digital transfer technology to transfer real-time data over an individual network. In ATM, the data stores in specific and fix-size packets transferring overtime.
