Metropolitan Area Networks

  • Anthony S. Acampora
Part of the Applications of Communications Theory book series (ACTH)


As discussed in the introductory chapter of this book, the earliest need identified for a Metropolitan Area Network was to provide connectivity over an extended geography among devices connected to different Local Area Networks (see Figure 1.6). For this application, it was envisioned that the MAN would consist of a single high-speed multiple access channel, and that a single access station on each of the interconnected LANs would serve as that LAN’s gateway to its corresponding MAN access station. The traffic presented by a LAN to a MAN access station would be aggregated traffic, that is, time-multiplexed traffic generated by a multitude of devices connected to that LAN, needing to be transferred across the MAN to receivers connected to remote LANs. In effect, each LAN serves as a statistical multiplexer for locally generated traffic destined for other LANs, and this statistically multiplexed (or aggregated) traffic is the load presented to the MAN through each LAN’s corresponding MAN access station.
