Using CORBA notification service and RSVP to provide end-to-end QoS guarantees

CORBA is an object-oriented middleware architecture defined by the Object Management Group (OMG). It is designed to support the development of distributed applications by separating interfaces from implementations, automating many of common network tasks, and adding several services. Unfortunately, CORBA does not consider quality of service (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.
