A new class of distributed systems are beginning to employ DDS technology. These systems are characterized by broad geographic distribution, high aggregate data volumes, and narrow data interest within any particular node or local application. This presentation describes a set of enhancements to DDS and DDS-RTPS to better support such systems, in particular in the areas of data filtering and service discovery.

Integration effort and risk grow dramatically with system and team size. Connecting large systems developed by independent teams at different times requires connecting multiple systems, thus creating a system of systems. Enterprise systems use a design called Service Oriented Architecture (SOA) to effect this integration. However, the technologies used in the enterprise do not apply well to real-time systems; they cannot handle the strict delivery and timing requirements. So what IS Real-Time SOA?
