Incremental Scheduling of Mixed Workloads in Multimedia Information Servers

摘要

In contrast to pure video servers, advanced multimedia applications such as digital libraries or teleteaching exhibit a mixed workload with massive access to conventional, "discrete" data such as text documents, images and indexes as well as requests for "continuous data", like video and audio data. In addition to the service quality guarantees for continuous data requests, quality-conscious applications require that the response time of the discrete data requests stay below some user-tolerance threshold.
