....moves down. To avoid thrashing, all the layers of the active streams are locked and hence spared from being replaced. Such a policy ensures that ultimately, the number of layers of a stream is proportional to its popularity. 24 4. 6 Adaptive Prefetching The contents of this section are based on [10]. The primary aim of prefetching is to hide I O latency and jitter for multimedia applications. Good prefetching decisions depend on two sources of information: a) application behavior and QoS requirements, and (b) system resource availability and performance characteristics. Now, the problem is ....

.... quality of service parameters and with policy level (policing and bandwidth reservation) functionality[18, 19] For real time and embedded applications, researchers have developed languages for stating service contracts and methods for adapting programs at runtime to meet such contract obligations[42, 43]. In addition, there are formulations and implementations of objects and invocations that are able to meet timing attributes [46] or more generally, QoS objects [57] that permit the association of arbitrary service contracts with objects and object invocations. Similarly, research in high ....
....this research from our own past work[4, 22] in which we investigated how the needs of real time applications affect the object model and its 4 required runtime support . Last, in comparison to ongoing work addressing the online adaptation of distributed multimedia or embedded applications[42, 43, 45], such work is typically emphasizing the development of adaptive methods for certain classes of applications. Such methods may be realized in CTK using its notions of attributes and policies. Recent work on reflective programming[20, 11] and on Quality of Service objects[57] is now leading ....
