REINAS Networking

REINAS is a large, distributed, system,made up of literally hundreds of components that can be (and are)scattered across a geographic area of several hundred square miles, or more.REINAS instrument nodes aredesigned and implemented as Internet nodes as well, yet they may bemobile and/or located in areas that have no conventional connectionsto the Internet. As a result, REINAS has extended the Internet with a wide-area networkto support its instrumentation, utilizing a variety of state-of-the-artand conventional network technologies, including:
  • low speed point-to-point wireless links (9.6 kbps)
  • low speed point-to-point leased-line links (14.4 kbps)
  • medium speed point-to-point and multipoint wireless links
    (57.6 kbps and 64 kbps)
  • high speed wireless wide-area networks (1.5 Mbps)
  • high speed point-to-point wired links (1.7 Mbps)
  • high speed local-area ethernets (10 Mbps)
Figure 4.1 shows the wide-area networkused operationally within REINAS in the Monterey Bayregion. All links shown rely on the Internet Protocol (IP)as the underlying transport mechanism for system and application-levelprotocols.

This network supports data collection from a variety of instruments,from simple meteorological stationsto live video cameras,as well as remote users of the system.

REINAS' networking requirements continue to foster ongoing researchinto new wireless Internet protocols, especially those supportingvideo transportand mobile computing.
