CORBA is an object-oriented middleware defined by the OMG. It is designed to support the development of distributed applications by separating interfaces from implementations. Unfortunately, CORBA does not consider QoS requirements inherent to new applications such as teleconferencing and telecommunication services. The Resource reSerVation Protocol (RSVP) is an IETF protocol that allows real-time applications to reserve necessary resources at routers along the transmission paths, so the requested bandwidth can be available when transmission actually takes place. In this paper, we discuss the use of Notification Service and RSVP to provide end-to-end QoS to applications supported by CORBA architecture.
