This paper discusses the effectiveness of a data-driven implementation of interface for protocol/media processing in multimedia networking environment. realtime multi-processing in network/media processing are necessary in multimedia networking environment to meet time constraints in each media. In protocol handling which is typical one of network processing, however, pseudo multi-processing on von Neumann processor can't meet time constraints because of runtime overheads by Context switching. Therefore, the authors proposes implementing protocol/media processing on CUE (Coordinating Users' requirement and Engineering constraints) series data-driven processor which realize realtime multi-processing without runtime overheads. This paper describes a data-driven implementation of protocol handling used in CORBA (Common Object Request Broker Architecture) to realize realtime multi-processing and programmability for flexible protocol handling. Then, we propose data-driven I/O interface for multimedia networking environment. To utilize performance of CUE processor, it is important to keep steady input. We study Data-Driven I/O interface which realize ideal input stream and handshake control without bottlenecks.
