Abstract: Evaluation through simulating is a major measure to validate researcher’s conclusion in streaming media cache research. It can truly evaluate research conclusion and condense the period of research. This paper introduces a simulator of streaming media cache named LittleDuck. Convenience for adding new cache mechanism and rapidity for obtaining simulation result is two characters of LittleDuck. It has great effect on the development of interrelated research area.
