MAN (Metropolitan Area Network)

MAN is called a metropolitan area network and it is a subset of WAN, the coverage area of MAN is lesser than WAN but more than LAN, LAN is a subset of MAN, MAN has multiple devices connected, LAN Range and proximity is way smaller than WAN, MAN is a complex and sophisticated in nature, maintenance, and development of MAN is expensive and only enterprises can afford and install it.

The common example of MAN includes CABLE TV NETWORKS | TELEPHONE NETWORKS | ISPs  | RESEARCH AND DEVELOPMENT NETWORK | EDUCATION INSTITUTES and many more…

The man can are broadly divided into 3 types :

1) FDDI (fiber-distributed data interface)

2) ATM (asynchronous transfer mode)

3) SMDS (Switched multi-megabit data source)

MAN offers high bandwidth and high-speed data communication, MANs are very efficient networking technology, they provide high-speed fiber optic data transfer. MAN provides high speed, its coverage is higher, so the operations can be said to be similar to ISP, MAN is operated via layer 2 of the OSI model.

MAN can usually extend to 30+ KM and standards have been devised by IEEE like DQDB for high bandwidth, high-speed data transmission. ISP and MAN are not the same, integrating MAN is more expensive than just setting up ISP at the enterprise level.

ISP may find conflict of interest when it comes to MAN and a lot of these conflicts of interest have been highlighted recently.

MAN evolution is based on the evolution of LAN TECHNOLOGY, EARLIER DAYS TELEPHONE lines were LEVERAGE TO CARRY OUT DATA CONNECTION, DUE TO THE LIMITATION OF Telephone lines as they couldn’t channel high data volume.

Fiber optics LAN-based systems were introduced which lease to the stepping stones of MAN, MAN can be adapted in the retail space but is heavily adapted in the enterprise space, as adaption standardization and implementation of an experience demand the right set of HUMAN RESOURCES, Computing resources, storage resources, computing resources, storage resources, networking resources, and hardware resources.

MAN most common use cases include: Digital cable service | Broadband service | Educational institutes | Research labs | Libraries | Hospitals | Government departments | Airports | Railway station

MAN  is a cost-effective solution for business and enterprise clients and is more secure/stable/reliant/reliable, as it reduces dependency on ISPs for providing networking capabilities.

MAN is much faster then WAN, hence low latency, high throughput communication, and networking change can be established all across the enterprise in a secure, efficient, and robust manner

In simple words, all the devices in the metropolitan Areas (30KM ) are connected via MAN, MAN consists of multiple LANs, connected, and the fiber optics used in MAN are leased by ISP.

Both CAN and MAN are prone to DDOS attacks and mitigation steps need to be implemented to mitigate attacks.

LAN was very well established globally, but for connecting multiple LANs businesses needed to rely heavily on the telephone network, even though the telephone network was able to transmit data packets it was not good at handling the high bandwidth utilization, traffic packets, high data packet flow resulted in inefficient networking and communication operations.

The single-mode optical fiber and data fiber technology are heavily leveraged to rectify the underlying issue. Internet exchange points were established to connect MAN with global internet gateways.

A MAN is optimized for higher geographical areas, MAN HAS MULTI LAN all inter-connected with intranet and extra-net, MAN has high speed and offers low latency and high throughput with a high level of networking capabilities.
