Therefore the goal of MAN is to develop a communication link between two independent LAN nodes. A public, high speed network, capable of voice and data transmission over a distance of up to 80 kilometers (50 miles). A Metropolitan Area Network (MAN) is a network which connects various computers, resources and users in a geographical spread larger than a Local Area Network (LAN) but has a smaller area than a Wide Area Network (WAN). But while the telephone network was able to support the packet-based exchange of data that the various LAN protocols implemented, the bandwidth of the telephone network was already under heavy demand from circuit-switched voice, and the telephone exchanges were ill-designed to cope with the traffic spikes that LANs tended to produce. This situation is significantly improved with the extension of the HSR network in the HSR scenario, as shown in Fig. Like other metropolitan dark fibre networks at the time, the dark fibre network in West Berlin had a star topology with a hub somewhere in the city centre. Looking for the abbreviation of Metropolitan Area Network? Thus, several LANs could be connected by the use of bridges and backbone lines. [9], Internet exchange points (IXs) have historically been important for the connection of MANs to the national or global Internet. Exchange points also serve as low-latency link between campus area networks, thus the Massachusetts Institute of Technology and the Boston University could exchange data, voice and video using the Boston MXP. (LAN), a computer network dedicated to sharing data among several single-user workstations or personal computers, each of which is called a node. [4]:16, Metro Ethernet, where a fibre optic ring within a larger city was built as MAN backbone carrying Gigabit Ethernet, became common.

A major city, especially the chief city of a country or region: Chicago, the metropolis of the Midwest. DWDM platforms also alleviated the need for protocol conversion to connect LANs in a city, because any protocol and any traffic type could be transmitted using DWDM. [6], The metro Ethernet rings that did not route IP traffic, instead used one of the various proprietary spanning tree protocol implementations, so that each MAN ring had a root bridge. Useful english dictionary. A wireless metropolitan area network (WMAN) is a form of wireless networking that has an intended coverage area — a range — of approximately the size of a city. metropolitan area network. Further examples of metropolitan Internet Exchanges in the USA that were operational by 2002 include the Anchorage Metropolitan Access Point (AMAP), the Seattle Internet Exchange (SIX), the Dallas-Fort Worth Metropolitan Access Point (DFMAP) and the Denver Internet Exchange (IX-Denver). The metro rings also connected many cities to the Internet that went on to become part of the Silicon Valley tech-hub, such as Fremont, Milpitas, Mountain View, Palo Alto, Redwood City, San Bruno, San Carlos, Santa Clara and Sunnyvale. Within the MAN of larger cities, metropolitan exchange points now play a vital role. 1st Jan 1970 Information Technology Reference this Disclaimer: This work has been submitted by a university student.

Adelaide Metro is the public transport system of Adelaide, the capital city of South Australia.It is an intermodal system offering an integrated network of bus, tram, and train service throughout the metropolitan area. The Amsterdam Internet Exchange (AMS-IX) is the world second largest Internet Exchange and has attracted companies to Amsterdam that are dependent on high speed internet access. While most people refer to a network in terms of being either a LAN or a WAN, an additional category that exists is called a metropolitan area network (MAN). Abbreviated MAN. Personal area network (PAN) This list of metro systems includes electrified rapid transit train systems worldwide. How Metropolitan Area Networks (MAN) works. RFID reader, interrogator. DSL line. It is generally applied to connect geographically dispersed LANs. [5] In the USA the Sprint Corporation was at the forefront of building fibre optic rings that routed IP Packets on the MAN backbone. [8] While the IEEE tried to standardise the emerging Ethernet based proprietary protocols, industry forums such as the MEF filled the gap and in January 2013 launched a certification for network equipment that can be configured to meet Carrier Ethernet 2.0 specifications. Similarly, Frankfurt has become a magnet for data centers of international companies because it hosts the non-profit DE-CIX, the largest Internet Exchange in the world. 3.
