Network Resource Gateway (NRG) Application DevelopmentDSLD Unit Florin van Slingerland Rev A Slide 18 The SDK contains the following API’s: Core API The Core SDK is a Java implementation of the H-OSA protocol. Utility API The Utility SDK goes one step further as it offers an abstraction from not only CORBA but also H-OSA. It does so by combining a series of H-OSA invocations and responses and offering this series through a simplified, proprietary API. Test API The Test SDK can be used at design time to simulate the NRG.
