Some lessons learned from the practical experience using MANs

Abstract

An attempt is made to define a metropolitan area network (MAN) from a practical point of view, and the advantages and disadvantages of a public MAN and a private MAN are compared. Some discussion on the MAN's goals, strategies, technologies, and markets is offered related to MANs and the probable evolution to broadband integrated services digital network (B-ISDN), while broadband communication is on its way to becoming reality. A possible evolution from existing narrowband ISDN exchanges to a universal, ATM-based B-ISDN is outlined.<>
