....Cheerio file format to the user. Any application reading the file with read( would see the flat version; any conversion from the hierarchical Cheerio format would happen transparently. Some work has been done in this direction, but not in the context of parallel 67 file I O. The Zodiac project [NCS97, CMNY98] has built a media file system that supports e#cient inserts. 7.3 Research of theoretical interest In addition to the systems projects described above, there are three areas of theoretical research that may prove fruitful. Describing the Cheerio file format The structure of the ....

....throughput 1Introduction Video on demand (VOD) 1, 2] is the basic technology for many important multimedia applications such as digital video libraries, distance learning, company training and electronic commerce. Such a system typically stores a large number of videos in one or more servers [3,4,5,6,7,8,9]. When a request for a video arrives, it is loaded from disks in a server and transmitted to the clientinanisochronous stream [10,11] Since server resources are finite, the number of video streams a server can support simultaneously is limited, which is referred to as the server capacity. To ....

.... rather than deterministic guarantees) Providing deterministic service at the disk is complicated by the random service time costs involved in disk transfers (because of the random seek and latency overheads) This problem has been addressed effectively by suitable disk scheduling policies [1, 2, 3, 4, 5, 6]. These scheduling 2 policies group a number of requests into rounds or batches and service the requests in a round using a disk seek optimizing policy such as SCAN. Then the service time for the entire round can be bounded to provide guarantees. This strategy works well with CBR streams. An ....

....systems that can handle both real time continuous media data and non real time textual data. Both are single disk file systems and do not employ multi disk optimizations such as striping. Similarly, MMFS is a single disk file system that adds continuous media support to a FreeBSD based file system [20]. The Tiger Shark file system from IBM and XFS from SGI are results of commercial efforts to build integrated file systems [11, 12] These file systems come closest to Symphony in terms of the features offered. For instance, these file systems support variable size blocks (referred to as extents) ....

....the coexistence of multiple data type specific techniques. Symphony comprises a QoSaware disk scheduling algorithm for real time and nonreal time requests, and a storage manager supporting multiple block sizes and data type specific placement, failure recovery, and caching policies. MMFS [Niranjan et al. 97] handles interactive multimedia applications by extending the UNIX file system. MMFS has a two dimensional file structure for singlemedium editing and multimedia playback: 1) a singlemedium strand abstraction [Rangan et al. 91] and (2) a multimedia file construct, which ties together multiple ....

....an interval. Disk service tends to incur random service time costs because of the random seek and latency overheads involved in disk transfers. Much work has been done on providing deterministic service for CBR streams [1, 2, 3, 4] and many projects have started building servers for such service [5, 6, 7, 8]. Recently, statistical service for VBR streams received attention [9, 10] In this paper, we address the problem of providing deterministic service for VBR streams. Providing deterministic service at disk is complicated by the random seek and latency overheads involved in a disk transfer. This ....

Data streams can be classified as Constant Bit Rate (CBR) or Variable Bit Rate (VBR) depending on whether the stream requests the same amount of data in an interval. Much work has been done on providing deterministic service for CBR streams [1, 2, 3, 4, 5, 6] and many projects have started building servers for such service [7, 8, 9] Recently, statistical service for VBR streams received attention [10, 11] Much of this work concentrates on providing service guarantees required by continuous media in the context of Video on demand (VOD) servers.

....be used to model the behavior of change of sequence requests in an interactive video playback application or the requests in an interactive video game. These requests arrive at irregular intervals of time. Aperiodic requests are regular file requests. Disk scheduling for CBR requests is studied in [1, 2, 3, 4, 5, 6]. Our approach to providing QOS guarantees at the disk is shown in Fig. 1. We employ a two level scheme where bandwidth allocations and resource scheduling are separated. Disk bandwidth is allocated appropriately among the different types of requests. Each class of requests employs an admission ....
