Techniques for increasing the stream capacity of a multimedia server

A server for an interactive distributed multimedia system may require thousands of gigabytes of storage space and high I/O bandwidth. In order to maximize system utilization, and thus minimize cost, the load must be balanced among the server’s disks, interconnection network and scheduler.

This paper presents techniques for improving server capacity by assigning media requests to the nodes of a server so as to balance the load on the interconnection network and the scheduling nodes. Five policies for request assignment are developed. The nPrfnrmnnrP nf t.h.ese nnliriP.G 0% g serl_re?p-Q&l &y/T‘.J”. ..“_.“V1 1J I,“““-“-oped earlier is presented.
