....protection domains. While capacity reserves are useful for applications with a pri40 ori knowledge resource requirements, they are also useful in environments requiring dynamic QoS control [106] Virtual memory management for interactive multimedia applications has also been realized in RT Mach [136]. Modifying an existing operating system to support multimedia and real time applications is typically a major undertaking and prone to subtle timing issues. Commercial operating systems such as Solaris have been enhanced with some support for real time applications, such as fixed priorities and ....

....buffer. In this way, the buffers change task from receiving disk data to transmitting data to the network until all clients are served. The admission control adjusts the number of concurrent users to prevent data loss when the buffers switch and ensures the maintenance of all client services. In [Nakajima et al. 97] the traditional allocation and page wiring mechanism in Real Time Mach is changed. To avoid that privileged users monopolize memory usage by wiring unlimited amount of pages, only real time threads are allowed to wire pages, though, only within their limited amount of allocated memory, i.e. if ....

....ffl Continuous media applications should change the quality of media according to system load. The first facility is real time resource managements such as real time scheduling, real time synchronization and real time communication[10, 19] Also, processor reservation[1] and memory reservation[14] are used to protect CPU and memory resources of continuous media applications from malicious applications. The facilities ensure that video frames and audio samples should be deliver to a speaker and a display until their timestamps do not exceed the current time. If the timing constraints are ....

.... Japan Advanced Institute of Science and Technology 1 1 Asahidai, Tatsunokuchi, Ishikawa, 923 12, JAPAN 1 Introduction Resource reservation such as processor reservation and memory reservation is a promising approach for supporting timing critical applications such as continuous media applications[1, 4, 7, 11, 12]. However, it is difficult to predict how much resource is consumed for respective applications before executing the applications. In real time communities, the schedulability analysis can be used to map QOS values of continuous media applications to their resource utilization. The approach is ....
