Next Generation Network （NGN） service platform is a distributed system and must ensure quality of service supportfor value-added service in communication. Real-time CORBA adopts object-oriented methods to enhance the reusabilityand extensibility of distributed application software

which largely simplifies the development and maintenance ofdistributed application system and makes the system integration easy in heterogeneous environment. Furthermore itprovides the end-to-end predictability in distributed real-time application. Following the discussion of the resourcecontrol strategies and the protocols framework in implementation based on real-time CORBA specifications and theimplementation technologies of its products

the results of experiments verify its performance. Real-time CORBAimproves the real-time performance of general CORBA

hence

it can provide quality of service when applied in NGNservice.
