An adaptive scheduling approach in real-time CORBA

CORBA is an emerging middleware infrastructure with open standardization that is receiving a good acceptance since it allows easier programming of distributed objects. CORBA is being extended through the specification of interfaces and necessary abstractions to support applications with real time constraints. These new abstractions will enable a variety of programming models for real time applications. The paper presents an adaptive programming model for distributed real time applications using CORBA concepts. The model combines the time polymorphic invocation technique with the (m,k)-firm guarantee.
