Abstract

At W. M. Keck Observatory we recently examined and prototyped what it would take to adapt publish-subscribe middleware, namely Data Distribution Service (DDS), to a remote procedure call (RPC) style peer-to-peer architecture. The design and prototype was based on the middleware neutral Common Services Framework (CSF) in use by NSO for the Advanced Technology Solar Telescope (ATST). The paper describes the process used to adapt DDS for RPC style commands. It highlights the differences encountered between the RTI and PrismTech implementations, and contrasts the ICE based connection service in CSF to one based on DDS.
