- Abstract
- This paper proposes a DSM-CC carousel caching and management architecture that can support both priority-based scheduling of monitoring threads and caching of carousel objects for a quick launch and download of Xlet. The carousel objects are broadcast cyclically by the transmission policy. Lack of carousel object reception may cause performance deterioration. The data broadcasting middleware should guarantee real-time characteristics such as the processing time in periodic monitoring threads to detect a change in information without a long latency time. Therefore this proposed architecture can improve the predictability of periodic monitoring section filter threads by using the managing the thread pool and scheduling periodic threads. To guarantee fast launch of the data broadcasting application, this paper also proposes the cache control mechanism of DSM-CC data/object carousel. This proposed architecture can accommodate data broadcasting middleware that uses DSM-CC object carousel mechanisms, such as ACAP, OCAP and MHP. © 2006 IEEE.
