History of the Metropolitan Area Network
In the 1940s in America there was a study that wanted to use a computer device together. In the 1950s when the type of computer began to grow until the creation of a super computer, because of the high price of computer equipment, there was a demand that a computer must serve several terminals.
From this, the concept of time-based process distribution emerged, known as the TSS (Time Sharing System), the first form of computer networking applied. In TSS systems several terminals are connected in series to a host computer.
Furthermore, this concept developed into a distribution process (Distributed Processing). In this process several computer hosts do a large job in parallel to serve several terminals that are connected in series to each host computer.
When the prices of small computers have begun to decline and the concept of the distribution process has matured, the use of computers and networks has begun to vary from beginning to handle shared processes and communication between computers (Peer to Peer System) alone without going through the central computer. For this reason, network technology such as LAN, MAN and WAN began to develop
Metropolitan Area Network (MAN) Implementation
Some of the technologies used for this purpose are Asynchronous Transfer Mode (ATM), FDDI, and SMDS. This technology is in the process of being replaced by Ethernet-based connections (for example, Metro Ethernet) in most areas. MAN connections between local area networks have been built wirelessly using either microwave, radio, or infra-red laser links. Most companies rent or lease circuits from general operators due to the fact that laying long cables that stretch is expensive.
DQDB, Distributed-queue dual bus, is a standard metropolitan area network for data communication. This is specified in the IEEE 802.6 standard. Using DQDB, the network can be up to 20 miles (30 km) and operate at speeds of 34-155 Mbit / s.
Some well-known networks started as MANs, such as MAE-West, MAE-East Internet peering points, and Sohonet network media.
Strengths and Weaknesses of MAN Networks
Advantages of MAN Networks
Data and information exchange can be faster and more accurate.
Development in the area of science for a college or schools.
Communication between colleges or schools or employees in an office can be by e-mail or chat.
The process of data backup from various places is easier and faster.
Can create a means of discussion for colleges or schools.
Can be used as a tool to unite employee or student cohesiveness and students.
Can be used as a means of promotion that is appropriate and fast.
Can use application programs or games together.
The coverage of the network area is wider than the LAN network
Lack of MAN Network
Relatively large operational costs
The maintenance costs are fairly expensive
Crackers often target for personal gain
To repair a MAN network requires quite a long time
MAN Network Losses
High operational costs.
Installing the infrastructure is not easy.
Complicated if there is network trouble (network trouble shooting).
To repair a MAN network requires quite a long time.
Can be the target of operations by Crackers for personal gain
Function and Purpose of MAN
Build & implement a network system that collaborates between servers to meet the internal needs of companies and governments in communicating the network used so that they can carry out activities such as chat, messenger, video and others with local bandwidth.
Types of Computer Networks MAN is commonly used to connect computer networks from one city to another. To be able to create a MAN network, telecommunications operators are usually required to connect between computer networks
The MAN Computer Network includes the wider network coverage area so that communication becomes more efficient, makes it easier to do business, and also security in the network becomes better
Able to support text and voice data, and can even be associated with cable television networks or radio waves
To connect computer networks from one city to another
