metropolitan area network (MAN)

Definition of metropolitan area network (MAN) in The Network Encyclopedia.

What is MAN (metropolitan area network)?

A term that can mean several things in different contexts:

  • Multiple local area networks (LANs) that are connected on a campus or industrial complex using a high-speed backbone.
  • Multiple networks that are connected within the same city to form a citywide network for a specific government or industry.
  • Any network bigger than a LAN but smaller than a wide area network (WAN).
  • A Distributed Queue Dual Bus architecture network based on the IEEE 802.6 standard of Project 802. This is the formal definition of a metropolitan area network (MAN), but it is essentially obsolete.
TIP

Fiber Distributed Data Interface (FDDI) is a good network technology for building a metropolitan area network (MAN).
