- Abstract
- The authors present the design of CAN-CORBA, an environment-specific CORBA for CAN-based distributed control systems. The ORB core of the CAN-CORBA has the following properties. (1) It supports subscription based group communication as well as the classical connection oriented point-to-point communication of CORBA; as a result, it better services the data multicasting requirement of typical control systems. (2) It significantly lowers the amount of message traffic required for each CORBA method invocation so that even the slow broadcast bus of the CAN can tolerate the overhead of CORBA method invocations. To seamlessly integrate two communication schemes into our extremely light-weight ORB, we design a transport layer protocol on the CAN that can support up to four different upper level protocols. We have implemented the CAN-CORBA on the mArx real time operating system developed at Seoul National University. Our experiments clearly demonstrate that it is feasible to use CORBA in developing distributed embedded control systems possessing severe resource limitations.
