Real-time middleware holds an important position in increasing distributed application development. As the basic platform
the middleware should satisty suchlike requirements: expression methodology of real-time constraints
real-time request scheduling mechanism
means of resource controlling and enabling the predictability of program lifecycle. This paper makes three contributions to the design of real-time middleware system. First
the paper defines the architecture of real-time middleware system. Second
under the analysis of distributed middleware applications
the paper presents a multi-level thread-pool real-time middleware model. Compared with traditional ones
the model has three advantages: better concurrent potential
more capability on network and resource controlling and higher system behavior predictability. Finally
the paper presents a real-time ORB under the specification of OMG realtime CORBA. Detailed experiments and comparison shows the efFciency of multi-level thread-poll real-time middle-ware model.
