Our work can be complementary to [18] 19] as we are focusing on the problem of selecting which part of the video should be cached, after the cache space for this particular video has been allocated. The rest of this paper is organized as follows. Section II gives the background and definitions. Section III addresses the video caching ....

....for caching multiple video objects onto the proxy. For the problem of caching multiple videos, some cache space allocation and cache replacement techniques should be applied, which are beyond the scope of this paper, and will be addressed only brie y in Section VI B. Readers can refer to [4] [13], 14] 5] 15] for more details. The proposed SCQ and SCB algorithms can be complementary to those cache space allocation and replacement schemes. B.

....al: 28] considered layered encoded multimedia streams. They proposed a proxy caching mechanism to increase the delivered quality of popular streams. Acharya et al.: 3] proposed the MiddleMan cooperative caching techniques, which utilize the aggregate storage of client machines. Reisslein et al.: [26] developed and evaluated a caching strategy which explicitly tracks client request patterns and achieves higher hit ratios. To the best of our knowledge, none of these schemes has considered measuring network bandwidth for caching algorithms, and none has used bandwidth models derived from real ....

Our focus in this study, however, is on gaining a fundamental understanding of the impact of the two basic streaming resources (bottleneck bandwidth C and cache space G) on the proxy performance. We refer the interested reader to [4], 5] 6] for a detailed discussion of the disk array limitations as well as discussions on replication and striping techniques to mitigate these limitations. We consider a caching scenario where the cache contents are updated periodically, say every few hours, daily, or weekly. The periodic ....

....of the stored video content from nearby servers, rather than accessing the video from a potentially distant server. In recent years, the area of web caching has received a great deal of attention from the research community [1] 2] However, as has been observed by a number of studies [3] 4] [5], 6] there are fundamental differences between the caching of conventional web objects (such as HTML pages and images) and the caching of streaming media objects (such as audio and video) First, streaming media objects require orders of magnitude more storage space than conventional web ....

....For the development of the disk model we assume for now that the video objects are placed in the proxy s disk array using the localized placement strategy. With the localized placement strategy each video file is placed contiguously on a single disk. We refer the interested reader to [20] for the analysis of a number of more complex striping placement strategies, whereby each video file is striped across a subset of the disks in the proxy s disk array. Now consider one of the disks in the proxy s disk array and suppose that this disk is servicing I streams. Let retr(I; T ) denote ....

....that the developed stream model also applies to the streaming from the origin server s disk array via the proxy to the client in the case of a cache miss. Because of page limitations we focus in this paper on streaming from a disk array with localized placement. We refer the interested reader to [20] for streaming from a disk array with striping placement. Consider a single disk in the proxy s disk array and suppose that this disk is streaming I video objects. For simplicity we assume that each video object has N frames and a frame rate of F frames per second. Let f n (i) denote the number of ....
