How does the MAN Network function?

MAN Network: What is it?

Similar to a local area network (LAN), a metropolitan area network (MAN) covers an entire city, campus, city, or other area controlled by a government or organisation.

In order to create MANs, many local area networks are connected. MANs are bigger than LANs but smaller than wide-area networks (WANs), which may directly connect users all over the world over massive geographic distances.

High-speed carriers, like fibre optic cables, can be used to transmit data quickly across a MAN. A wider range of signal transmission methods are becoming available with the introduction of wireless phones and subsequent networks.

In computer networking, a metropolitan area network (MAN) typically encompasses a whole campus or city centre. It offers up-link services to the wide-area network (WAN) and the internet and connects LANs utilising high-speed backbone technologies like fibre optics.

In metropolitan area networks (MANs), data transfers happen at a modest pace, and propagation delays are also reasonable. MANs’ networks are more congested and have lower fault tolerance. MANs are expensive, and one organisation may or may not own them.

This MAN can connect offices in a single city, factories or agencies, and the corporate headquarters within its range using a large network that offers coverage of between 10 and 50 kilometres.

MANs transfer data via a variety of tools, including modems and wires/cables. The high-speed DSL network of the telephone provider or the local network of the cable company are two examples of MANs.

Features of the MAN network

The Metropolitan Area Network (MAN) has a wide range of applications, but these are its primary ones:

The “obsolete” lines of analogue telephony or ISDN in urban areas will be eliminated with the adoption of VoIP services (Voice over Internet Protocol), eliminating the existing spending on these lines.

It is a local area network (LAN) connector.

All Wi-Fi channels can be accessed with the deployment of Wi-Fi zones without a wireless backhaul (Femtocell), which in practise results in a 60% increase in the connection of Wi-Fi users.
Easier connectivity between computers.
Local video surveillance systems.
Transmission using CAD/CAM.
Wide area networks (WAN) walkways.

The size of networks typically ranges from 5 to 50 kilometres. It might cover anything from a few college buildings to an entire metropolis.
In contrast to LANs, which are often held by a single organisation, MANs are typically owned by user groups or service providers who offer services to users.

It makes resource sharing within a region easier.

They serve to link LANs to WANs, the WAN, and the Internet.
MAN has moderate to high data rates.

Metropolitan area networks also ensure the transmission of high-quality voice, data, and video. For this reason, businesses with numerous departments in the same capital city must set up such networks.

How Does MAN Network Operate?

In MAN, which is bigger than LAN but smaller than WAN, the objective is to create a communication link between two autonomous LANs. In order to smoothly connect geographically distributed LANs, metropolitan area networks (MAN) typically integrate LAN and WAN.

Optical fibre is frequently utilised as a transmission channel in MAN networks. Through their ports, switches and routers help in data delivery. Data that is transmitted in frames must pass through a switch to be filtered.

Switches function as dual-port devices because they manage connections at one end while filtering data at the other.

Routers determine the path that data packets are to be routed along, which helps to facilitate the network connection. To put it another way, a router keeps track of data transit. The coverage range of the Metropolitan Area Network (MAN) is often up to 50 km.

The role and objectives of MAN

The development and deployment of a networking system that creates connections between servers on the government and business networks so they may interact via chat, messenger, video, and other services.

There are many different kinds of computer networks, but MAN is the one that is most frequently used to connect cities. Telecommunications providers must link computer networks over great distances to form a Metropolitan Area Network (MAN).

Communication will be more effective, conducting business will be simpler, and the network will also be safer thanks to the MAN Computer Network.
Both text and speech data can be supported, and it is integrated with a cable television or radio network.
The basic objective of MAN is to link computer networks between cities.

What distinguishes LAN, MAN, and WAN from one another?

Networks come in three different flavours: LAN, MAN, and WAN.

You can interact between multiple devices connected to a LAN via a LAN, or local area network. What you can accomplish with a local area network is governed by private ownership as opposed to public use.

You may want to read What is a Local Area Network, as well as the Types and Advantages of LANs.

LAN has a fast propagation delay compared to MAN and WAN. The smallest areas, such as colleges, schools, hospitals, etc., are so covered.

A greater area than the local area network is covered by the MAN, sometimes known as the Metropolis area network. A MAN links multiple computers, whether they are in the same city or separate cities. Metropolitan area networks should not be owned by a single entity since they are expensive.

WANs, or wide area networks, can span an entire country or continent, covering a larger geographic region than LANs. They should not be managed by a single organisation because they are expensive. WAN frequently makes use of satellite or PSTN communication.

Let’s examine the distinctions between LAN, WAN, and MAN.

What is a metropolitan area network? and how does it operate?

Metropolitan Area Network Applications MAN is used for

  • Used in digital cable TV.
  • used by government institutions.
  • college campuses.
  • broadband via cable.
  • a system of firehouses.
  • airports use it.
  • used to supply LANs in a metropolitan area with Internet connectivity.
  • used to connect the local school’s many branches.
  • used in hospitals (for doctor, research office, and lab communication).
  • connecting community colleges around the nation.
  • used in community libraries.
  • Benefits of MAN

The following are MAN’s benefits:

High Speed: Thanks to MAN’s fiber-optic communication, data transmission rates for files and databases are quick. Transmission rates can soon exceed 1000 Mbps.
Internet sharing: The installation of MANs enables customers to share their internet access, enabling high-speed internet for a large number of users.
great Security: It provides great security compared to WANs and LANs, and data in MAN are often safe.
Less expensive: Because MAN is less expensive, it is simple to connect to the WAN network. Strong data efficiency is offered. It is simple to manage all MAN data centrally.
Sending Local Emails: MAN makes it simple and cost-free to send local emails.
Easy to Convert from LAN to MAN: Two or more LAN networks are connected via MAN. Consequently, it is a speedier way to link two LAN networks. The efficiency of the links allows for the process.

The drawbacks of MAN

The following are MAN’s drawbacks:

Internet speed disparity: Because copper connections slow down MAN, the fibre optic network cannot utilise them. As a result, fibre optic networks are more expensive than copper wires.
A Challenge To Manage: It gets much harder to administer LAN networks as their size and quantity rise. Additional configuration issues and security issues are the cause.
High danger of hacking: MAN is more susceptible to hacker attacks than LAN. As a result, having high-security people is crucial.
Technical Personnel Needed to Set Up: Highly technical individuals will be needed to configure MAN. Troubleshooters and network administrators will be the technical personnel.
Need Added wires MAN networks require more cables than LAN networks do. We know that MANs are created by combining two LAN networks.
