Data Transport Networks: Case Studies in a Public Transit Environment

The de facto standard for providing data transport not only throughout the Internet but also for numerous private and industrial networks has become Ethernet. Circuit-switched networks (or time-division multiplexed networks such as synchronous optical network (SONET)) used to be popular choices for applications that require flexible and reliable data transport, before Ethernet. Packet-switched networks in general (and Ethernet in particular) usurped the role formerly played by these circuit-switched networks over the past ten years. But the question needs to be asked whether this is a good development, given that not all applications that require data transport are created equally. This article explores The current trend of using packet-switched, as opposed to circuit-switched, networks in the context of providing data transport for rail-based public transit agencies is explored in this article, and, conclusions are drawn that are relevant for public transit agencies, after examining five case studies.
