Multicast data distribution on the AWIPS local area network
In the current AWIPS site architecture, meteorological data is stored centrally on a set of data servers, and
delivered to individual workstations on demand, as the visualization software requests it. FSL is investigating
augmenting this network "pull" approach with a local site multicast "push" of data to the workstations as the
data is received at the site. We expect this to reduce latencies in displaying data on the workstations, and
increase overall site data availability. There are a number of open design issues, including the optimal subset
of site data to broadcast, the data notification mechanisms, and whether to multicast transmission-format or
decoded data formats.
