Paper Abstract

In this paper, the design and implementation of a multimedia on demand file server on an inexpensive PC is presented. The server can efficiently record multiple media streams in the UNIX file format and playback multiple media streams simultaneously. The objective of the design is to provide high throughput and high predictable response time. The claims are verified by comparing the throughput, data loss rates and deviations of the response time of the proposed file server and the original file system. When multiple user requests of continuous stream access the file system simultaneously, the low level I/O scheduler alone is not sufficient to keep its I/O throughput at the full raw power. A high level access scheduler aiming at maximizing I/O throughput is presented in this paper. The applications of a read/write multimedia file server include video conference recording/playback, multimedia program store-and-forward hub, and multi-level multimedia storage system.
