Introduction

A metropolitan area network (MAN) is a computer network in which two or more computers or
communicating devices or networks which are geographically separated but in same metropolitan
city and are connected to each other are said to be connected on MAN. The limits of Metropolitan
cities are determined by local municipal corporations and we cannot define them. Hence, the
bigger the Metropolitan city the bigger the MAN, smaller a metro city smaller the MAN.
The IEEE 802-2002 standard describes a MAN as being:
A MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of
buildings to entire cities. MANs can also depend on communications channels of moderate-to-
high data rates. A MAN might be owned and operated by a single organization, but it usually
will be used by many individuals and organizations. MANs might also be owned and operated
as public utilities. They will often provide means for inter-networking of local networks.
