Abstract :
Quality of service (QOS) is one of the most important factors in multimedia computing. Future continuous media applications should guarantee their QOS values provided by users, and support dynamic QOS control schemes by changing the QOS values according to system load. A processor reservation system developed in CMU is suitable for guaranteeing QOS, but it is not appropriate to support an application with a dynamic QOS control scheme. In this paper, we describe a new processor reservation system which is suitable for dynamic QOS control schemes. It consists of two components: user-level admission server and kernel support. The user-level admission server negotiates processor resources among applications, and the kernel support notifies the malicious use of processor resource by applications
