A Local Transaction Service Model for CORBA Collocated Components

CORBA collocated components´ communication in current implementations of CORBA Component Model often suffer from unreasonable communication overheads when components are collocated. This is because calls to collocated components also go through ORB. Elimination of these overheads is quite beneficial to crucial applications especially real-time ones. Several attempts had been made to minimize collocated components´ communication overheads by differentiating remote requests, which are passed through ORB, from local requests, which are handled locally without intervention of ORB. One such solution has only provided support for local requests of method call type and implemented it in CCM. This paper augments this solution by providing a real transaction service support for local components
