In recent years they have served to give a evolution of technology which has helped considerably the world of virtual networks. This is how thanks to all the new technological implements that exist have created new knowledge capable of achieving things that were previously unthinkable.
Due to the new technology implementations a breakthrough has been triggered in virtually all existing areas. This is how the data transmission networks have been created, among which we find networks LAN, MAN and WAM, and have become something necessary for society today in day.
According to their importance, here we are going to explain what a MAN Network is specifically, what it is used for and what types of this network exist.

What is a Metropolitan Area Network and what is it for in computing the WMAN?
Metropolitan Area Network (MAN). You can say that a MAN Network is the intermediate point between what is a LAN network and WAM. Specifically when we talk about Metropolitan Area Network we mean those high-speed networks that are capable of offering coverage to a fairly extensive geography.
However, until now it has never exceeded the dimensions of a city. They can reach speeds of up to 10 GB / second using cables optical fibers.
These MAN networks are commonly applied by different organizations worldwide, in companies, corporate offices in and around cities, among others. Which do not contain any type of switching element . That is, they divert information packets through several potential output lines. In addition, these networks can become public or private.
What types of metropolitan networks exist?
Metropolitan area networks are characterized mainly by offering many applications, among the main ones are the following:
- Interconnection of digital telephone centralist (PBX and PABX).
- Computer to computer interconnection.
- Interconnection of local area networks (RAL).
- Image and video transmission.
- Transmission of CAD/CAM.
- Gateways for large area networks (WANs).
Components of a MAN network What do you need to create one?
In order to create a MAN Network it is necessary to know what its components are:
Jobs
When we mention jobs we refer to the different systems from which different users demand applications and services provided by the network. Usually, within these jobs we find:
- Central computers.
- Workstations.
- PCs or compatible.
Wiring system
It is made up of the cable used to make the connection between the nodes of the network and the corresponding jobs .

Network nodes
These devices are those whose main mission is to be able to provide services to the different jobs that are part of the network.
Among its main functions we can find the following:
- They allow obtaining the access rights to the transmission medium.
- Offers a temporary storage of the information to be transmitted until the transmission channel is released.
- Filtering the information circulating through the network, where you only accept the own information.
- It offers a conversion of the information , in series, to information of the job.
Communication protocols
These are the rules and procedures that are used by the network to establish a communication between the nodes . Within these protocols different levels of communication are defined or classified. That is why metropolitan area networks support what is level 1 and a part of level 2 . All this serves the protocols of higher levels to follow the hierarchy OSI for open systems.
Applications
In the applications we find the MHS message handling system , the management, access and transfer of files ( FTAM ) and EDI to network applications possible.
