	Metropolitan area network - Wikipedia, the free encyclopedia
		Metropolitan Area Networks or MANs are large computer networks usually spanning a campus or a city.
		For instance a university or college may have a MAN that joins together many of their local area networks (LANs) situated around site of a fraction of a square kilometer.
		Then from their MAN they could have several wide area network (WAN) links to other universities or the Internet.

	Metropolitan Area Network (MAN) (Site not responding. Last check: 2007-11-07)
		A metropolitan area network (MAN) may be a network that is connecting multiple local area networks of an organization situated in some square kilometre buildings.
		Many metropolitan area networks (MANs) cover an area the size of a city, although in some cases MANs may be as small as a group of buildings.
		The metropolitan area network (MAN), its communications links and equipment are generally owned by either a consortium of users or by a single network provider who sells the service to the users.

	Metropolitan Area Network (MAN) (Site not responding. Last check: 2007-11-07)
		A Metropolitan Area Network (MAN) is one of a number of types of networks (see also LAN and WAN).
		Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings or as large as the North of Scotland.
		A MAN often acts as a high speed network to allow sharing of regional resources (similar to a large LAN).

	metropolitan area network - a Whatis.com definition - see also: MAN (Site not responding. Last check: 2007-11-07)
		A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
		The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network).
		It is also used to mean the interconnection of several local area networks by bridging them with backbone lines.

	Photonic local/metropolitan area network - Patent 4970717
		The local area network of claim 4 further comprising switching delay means coupled to the output of said first packet detector having a delay which is substantially equal to the time required to operate said switching means.
		The local area network of claim 5 further comprising control circuit means coupled to said first and second packet detectors and said first and second switching means to selectively pass an arriving packet at the second node or to loop-back the arriving packet to said first node over said second optical fiber path.
		The proposed invention deals with the local/metropolitan area networks, as opposed to wide-area networks in "Blazenet" the difference being the number of packets that are stored in the loop-back path and, consequently, the switching algorithm used by the switching nodes.

	Metropolitan Area Network and MAN Protocols
		Metropolitan Area Network(MAN)is a computer networks usually spanning a campus or a city, which typically connect a few local area networks using high speed backbone technologies.
		Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings.
		The Metropolitan Area Network (MAN) protocols are mostly at the data link level (layer 2 in the OSI model), which are defined by IEEE, ITU-T, etc.

	MAN :: Metropolitan Area Network
		MAN / Metropolitan Area Network is much like a WAN / Wide Area Network in that it is larger than a mere LAN / Local Area Network, which is located within a single location, but it is located within one geographical location such as the metro St Louis area.
		So a MAN / Metropolitan Area Network is much bigger than a single small network in one business location, but not spread out over the country or the world.
		A MAN / Metropolitan Area Network must be connected by a third party such as normal telephone wires, but should be less expensive than the typical WAN / Wide Area Network since all connection charges are local.

		Specifically, a MAN is a single, separate, identifiable "metro area network" that is owned and run by a single network operator, usually a service provider or carrier.
		The MAN is the network, or set of networks, that picks up traffic from the LAN and passes it to the WAN or to another LAN in the same metro area.
		The explosion of data traffic in the MAN has produced a new breed of service provider, one that is focused on profiting from the combination of raw data bandwidth, enhanced network control, cost-effective technologies, and the convergence of data, voice and video into a massive, profitable data stream.

	Telecommunications: More Relief for the MAN? - metropolitan area network - Technology Information
		ILEC networks are hierarchical in nature: access nodes feed aggregation nodes, which in turn feed the core offices.
		While all-optical networking offers the means to minimize and even eliminate these conversions, there are situations where it is necessary: wavelength translation (to avoid blocking and stranded capacity) and regeneration (to ensure signal integrity).
		Furthermore, if the control plane for all-optical networks is to be capable of establishing end-to-end connections through a general mesh topology, it must be capable of performing traffic engineering functions including resource discovery, state information dissemination, path selection and path management.

		As a result of the instigation of the network, Abbey National saved on Parallel Sysplex IBM license fees, which in itself paid for the project over a couple of years.
		Guiding all areas of the project was 'resilience' -- such a large network would be exposed to a variety of 'threats', such as traffic, road works, water, etc., all of which had to be planned for and negated.
		The success of the network and the training was immediately evident to Abbey National, who had been using externally managed services for their networking prior to the instigation of their own cable network.

	Metropolitan technologies will benefit providers and users
		Service providers in the metropolitan-area network arena are in the midst of a technology explosion that promises to bring customers lower bandwidth costs, more flexible service provisioning and a wider range of service options.
		A few providers, such as Yipes, have committed to supporting voice on their Ethernet metropolitan networks, but the quality of this service is as yet unproven.
		Metropolitan providers can use this technology to squeeze more capacity out of the fiber they lease or own.

	Telecommunications: Breaking the MAN Bottleneck - metropolitan area network - Technology Information
		SONET transport rings, on which MANs are based, provide the reliability needed for voice, but SONET, as it is traditionally used, tends to be inefficient for mixed voice and data services.
		Providers are recognizing that they need a new MAN optical infrastructure that comprehends the network's changed needs, increases bandwidth and makes it easier to supply voice, data and video services cost effectively.
		For example, a l0-Mbps Ethernet private network would require only seven DS1s of bandwidth to transport, but for economy the customer is likely to lease an entire DS3, leaving the bulk of the pipe unused.

	HORNET (Site not responding. Last check: 2007-11-07)
		Conventional WDM metropolitan area networks (MANs) are used as distribution networks to link the high capacity backbone to the access, local area, and campus area networks.
		HORNET is a WDM MAN ring that uses packet-over-WDM technology to form a multiple-access ring architecture instead of a ring formed of point-to-point links (we define packet-over-WDM as packet-switching at the optical layer, instead of at the network layer).
		This allows HORNET to be optimized for metro area traffic conditions as content is distributed throughout the network, and bursty, unpredictable packet-based communications is required between all access points on the network.

		In common with the London MAN, most use ATM (Asynchronous Transfer Mode), which is the latest development in networking technology, to provide connections at data rates of up to 155 Mbits/s.
		Although the primary purpose of the London MAN is to provide better Internet access to the connected sites, one of the benefits of ATM is that it enables other types of network applications such as video-conferencing and telephony to use the network simultaneously.
