RMMC programming model and support execution engine in the TMO programming scheme

While the conventional remote method invocation mechanism has been considered for a long time as the primary approach for facilitating interactions among real-time objects, a multicast support mechanism has been recognized in recent years as an attractive supplement, if not a favored approach, in many applications. One highly promising concrete formulation of a multicast mechanism and an associated programming model is the real-time multicast and memory-replication channel (RMMC). This paper presents an API set designed for facilitating easy use of RMMCs and a middleware subsystem devised to support RMMCs. An experimental study performed to validate the RMMC support facility and check the performance of a TMO-structured multimedia application which uses an RMMC, is also discussed.
