Optimized SCA descriptors with run-time deployment additions
Systems and methods for converting Software Communications Architecture (SCA) XML files into optimized SCA descriptors usable by a SCA Core Framework (CF) for application deployment and installation. The optimized SCA descriptors include sufficient run-time information so as to be directly usable by the CF for deploying and executing waveform applications without copying to different structures. The optimized SCA structures include component instantiation direct indexes into a sequence of partitions. The optimized SCA descriptors can be Common Object Request Broker Architecture (CORBA) structures provided in Common Data Representation (CDR) format.
