Real-Time Inter-ORB Protocol on distributed environment

Abstract

The paper describes the design and implementation of Real-Time Inter-ORB Protocol suited for multimedia applications on the CORBA environment. Conventional CORBA is not well suited for real time applications, since it does not define policies nor mechanisms to provide QoS guarantees, and does not define key features that are necessary to support real time programming. The existing TAO's RIOP for Real-Time CORBA has a mechanism to transfer QoS information but has a lack of support for QoS enforcement to achieve those QoS requests. In order to solve this problem, the paper suggests an integration of GIOP/IIOP with RSVP for Real-Time CORBA. A key feature is presented: QoS enforcement, which is provided for Real-Time CORBA by integrating IIOP with RSVP.
