Realtime multimedia applications such as conferencing, broadcast video, and distributed virtual reality demand predictable QoS from both endsystem and network resources. We argue that in a general-purpose computer, applications do not know the exact resource requirements in advance, and resource requirements and resource availability change at runtime. To(More)
The Development of distributed, multimedia, collaborative applications requires resolution of communication issues such as concurrency control, and temporal and causal synchronization of traffic over related data streams. Existing transport and/or session layer protocols do not include desired support for multi-stream, multipoint communication. In this(More)
We provide an overview of a CPU management algorithm called RAP (Rate-based Adjustable Priority Scheduling) that provides predictable service and dynamic QOS control in the presence of varying compute times, arrival and departure of processes, and CPU overloads. A signiicant feature of RAP includes an application-level QOS manager that implements policies(More)
Predictable Quality Of Service (QoS) in terms of controlled response time and guaranteed bandwidth is increasingly important in World Wide Web. We propose a variety of enhancements and extensions to the existing Web infrastructure so that Web applications and applets can provide predictable quality of service. The proposed extensions include addition of the(More)
1 Author names are in alphabetical order. Abstract Execution of an interactive collaboration application or a distributed game involves many individual multimedia applications that concurrently generate and/or play back several audio and video streams. As the resource requirements of individual streams change and as streams/applications are started or later(More)
