4.1.3.3 Metropolitan Area Networks

Metropolitan area Networks (MANs), a relatively newcomer, are the networks that are in between LANs and WANS. These networks are created to provide city-wide services in large cities and thus the name metropolitan. MANs fill the need of extending LAN capabilities to larger geographic areas. They are used to connect LANs across different offices in a city or to link LANs to WANS.
