- Abstract
- This paper proposes software architecture of a broadcasting file system that can support the prioritybased queuing of section filters and the caching mechanism of carousel objects. The data broadcasting software should guarantee the real-time characteristics such as the thread's processing time in periodic monitoring threads to detect the change of information. Therefore this proposed architecture can improve the predictability of periodic monitoring section filter threads by using the management of thread pool and the scheduling of periodic threads. To guarantee the fast launch of data broadcasting application, this paper also proposes the cache control mechanism of DSM-CC data/object carousel. This proposed architecture is able to accommodate the data broadcasting middleware that using DSM-CC object carousel mechanism such as ACAP, OCAP, and MHP.
