IEEE 802.6

The 802.6 Metropolitan Area Network (MAN) working group is concerned with the standardization of network protocols in the urban area and has standardized Distributed Queue Dual Bus

(DQDB) for MANs. In addition to this standard, the working group

is concerned withphysical layer protocols and has developed a proposal for a 100 Mbps protocol. This Physical Medium Dependent (PMD) is needed in looped-bus SMDS networks. Other working groups are concerned with the coupling of two LANs via a DQDB-MAN, with the transmission of video and with the variable bit rate
