Campus and Metropolitan Area Networks (MANs)
Martin P. Clark · 2001
Metropolitan area networks (MANs) are network technologies similar in nature to local area networks (LANs), but with the capability to extend the reach of the LAN across whole cities or metropolitan areas, rather than being limited to 100 metres or so of cabling. This chapter reviews the most important MAN technologies; FDDI (fibre distributed data interface), and SMDS (switched multimegabit digital service), which is based on the DQDB (distributed queue dual bus) technique.
