The M/sup 2/D/sup 2/ (multi-language programming, mobile objects, data interoperability, and dynamic compilation) framework is proposed for effective real time computing over the Internet. In this framework, a real time program is a collection of composite program objects coded in different languages native to the target processors for maximum performance. These composite objects will migrate from one Internet node to another to achieve the required fault tolerance, load balancing, and security consideration. The central idea is to perpetuate distributed objects by mobility so that they can continue to perform without interruptions caused by faults, load congestion, and unreliable results due to security breaches. Tests for the M/sup 2/D/sup 2/ framework have indicated that this method for effective real time computing over the Internet is a correct orientation and further investigations in the same direction will be worthwhile.
