Abstract

A class of constrained-latency storage access (CLSA) applications that require both large amounts of storage and guarantees for short latencies are presented. A range of existing approaches to meeting the requirements of CLSA applications is surveyed. Their limitations indicate that the technology does not yet exist to support complex CLSA applications on general-purpose storage architectures. A variety of good solutions exists for meeting throughput and latency requirements for continuous media data, including dedication of resources, presequencing, and greedy prefetching. However, none of the current approaches supports the automatic anticipation of scripted data access as required for interactive editing and playback of video segments.<>
