Research And Implementation Of CORBA's Mapping Based On C++ Language In PARLAY FRAMEWORK

With the development of the communication technologies,the communication pattern now in use can not meet the increasing needs of communication any longer,the customed business providing method shows its shortages also.The architecture of PARLAY/OSA has been recognized and acknowledged by people in their imagination about NGN.The architectures of NGN and PARLAY/OSA are introduced here.The first part of the paper mentions the background and technology advantage of PARLAY/OSA,analyses the basic running mechanism,emphasizes the point at the study of PARLAY FRAMEWORK and SCF,including the introduction to the PARLAY API function and detailed analysis of each interface.The second part of the paper discribes the distributed computing technology, introduces some typical technologies now existing and the problems they have.It also studies the CORBA technology that we will adopt.ORB and IDL which are the important components of CORBA are exampled subsequently.Finally, the paper introduces the CORBA production—ACE/TAO, based on which the design and complication of CORBA's mapping based on C++ language in PARLAY FRAMEWORK is introduced.
