MAN Network: What is it, what types are there and what are these metropolitan area networks used for?

These last few years have served to give a evolution of technology which has considerably helped the world of virtual networks. That’s how thank you all new technological tools that exist, new knowledge has been created 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 they were created data transmission networks, among which we find networks LAN, MAN and WAM, and they have become something necessary for society today.

According to their importance, here we are going to explain what specifically a MAN Networkwhat it is used for and what types of this network exist.

What is a Metropolitan Area Network and what is WMAN used for in computing?

Metropolitan Area Network or Metropolitan Area Network (MAN). It can be said that a MAN Network It is the intermediate point between what is a LAN and WAM network. Specifically when we talk about Metropolitan Area Network we refer to those high speed networks that are capable of offering coverage to a fairly extensive geography.

However, so far it has never exceeded the dimensions of a city. They can reach speeds of up to 10GB/second using wires from optic fibers.

These MAN networks are commonly applied by different organizations worldwide, in companies, corporate offices in the outskirts of cities, among other. which do not contain any type of switching element. That is, they divert information packets through various lines of transmission. potential output. Furthermore, these networks can become public or private.

What types of metropolitan networks exist?

Metropolitan area networks are mainly characterized by offer many applications, among the main ones we find the following:

• Interconnection of digital telephone switchboards (PBX and PABX).
• Computer to computer interconnection.
• Interconnection of local area networks (RAL).
• Transmission of images and video.
• Transmission of CAD/CAM.
• Gateways for wide area networks (WANs).

Components of a MAN network What is needed to create one?

In order to create a MAN Network, it is necessary to know what its components are:

Job positions

when we mention the jobs we refer to the different systems from which the different users applications demand Y services provided by the network. In general, within these jobs we find:

• central computers.
• Work stations.
• PCs or compatible.

wiring system

It is made up of the cable used to make the connection Come in the nodes of the network and the jobs corresponding.

network nodes

These devices are the ones whose main mission is to be able to provide services to the different Job positions that are part of the network.

Among its main functions we can find the following:

• They allow obtaining access rights to the transmission medium.
• Offers a temporary storage of the information to be transmitted until the transmission channel is released.
• Filtering of the information circulating on the network, where it only accepts the own information.
• Offers a information conversionserially, to job information.

Communication protocols

These are the rules and procedures that are used by the network in order to establish a communication between nodes. Within these protocols, different levels of communication are defined or classified. It is because of that metropolitan area networks bear what is level 1 and part of level 2. All this gives service to the higher level protocols to follow the hierarchy OR IF for open systems.

Applications

In the applications we find the MHS message handling systemthe management, access and transfer of files (FTAM) Y EDI to make network applications possible.
