A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area. The term MAN is applied to the interconnection of local area networks (LANs) in a city into a single larger network which may then also offer efficient connection to a wide area ...
A local area network (LAN) is a computer network that interconnects computers within a single physical location. ... (MAN) or a wide area network (WAN). ...
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
In addition, when the scope of a diagram crosses the common LAN/MAN/WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted ...
The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active.
A metropolitan-area Ethernet, Ethernet MAN, carrier Ethernet [1] or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or for internet access. Businesses can also use metropolitan-area Ethernet to connect their own offices to ...
Unlike IAN, LAN interconnects computers in a limited area, such as a home, a school, a computer laboratory, or an office building. The WAN also differs from the IAN because it is a network that covers a broad area, such as any telecommunications network that links across metropolitan , regional, or national boundaries, using private or public ...
Ethernet Virtual Private LAN or E-LAN: a multipoint service connecting a set of customer endpoints, giving the appearance to the customer of a bridged Ethernet network connecting the sites. Ethernet Virtual Private Tree or E-Tree : a multipoint service connecting one or more roots and a set of leaves, but preventing inter-leaf communication.
