The expanding scale and density of data centers has made their power consumption an
imperative issue. Data center energy management has become of unprecedented …

In this paper, we look at the problem of disk scheduling in a multimedia I/O system. In a
multimedia server, the disk requests may have constant data rate requirements and need …

Web services have a potential to enhance B2B e-commerce over the Internet by allowing
companies and organizations to publish their business processes on service directories …

This article provides a retrospective of our original paper by the same title in the
Proceedings of the First ACM Conference on Multimedia, published in 1993. This article …

This chapter describes the design for High-performance Data Recording Architecture
(HYDRA). Presently, digital continuous media (CM) are well established as an integral part …

Streaming media servers and digital continuous media recorders require the scheduling of
I/O requests to disk drives in real time. There are two accepted paradigms to achieve this …

Conventional admission control models incur some performance penalty. First, admission
control computation can overload a server that is already heavily loaded. Also, in large-scale …

We introduce an algorithm that uses buffer space available at the server for smoothing disk
transfers of variable bit-rate streams. Previous smoothing techniques prefetched stream data …

The performance of streaming media servers has been limited due to the dual requirements
of high throughput and low memory use. Although disk throughput has been enjoying a 40 …

A number of studies have focused on the design of continuous media, CM,(eg, video and
audio) servers to support the real-time delivery of CM objects. These systems have been …
