Abstract: This paper investigates the possibility of applying conception of QoS in the field of resource management in application specific operating system(ASOS) for handling multi-resource environments, and it develops a policy based approach to resource management to support quality of service. It also presents the general strategy, the design of a solution realizing the this approach, and a preliminary prototype implementation based on this architecture. Experimental result proves the availability of the algorithm.
