DESIGN OF A LARGE-SCALE multimedia STORAGE SERVER

Large scale multimedia storage servers will be an integral part of the emerging distributed multimedia computing infrastructure. However, given the modest rate of improvements in storage transfer rates, designing servers that meet the demands of multimedia applications is a challenging task that needs significant architectural innovation. Our research project, called Massively-parallel And Real-time Storage (MARS) architecture, is aimed at the design and prototype implementation of a large scale multimedia storage server. It uses some of the well-known techniques in parallel I/O, such as data striping and Redundant Arrays of Inexpensive Disks (RAID) and an innovative ATM based interconnect inside the server to achieve a scalable architecture that transparently connects storage devices to an ATM-based broadband network. The ATM interconnect within the server uses a custom ASIC called ATM Port Interconnect Controller (APIC) currently being developed as a part of an ARPA sponsored gigabit local ATM testbed. Our architecture relies on innovative data striping and real-time scheduling to allow a large number of guaranteed concurrent accesses, and uses separation of metadata from real data to achieve a direct flow of the media streams between the storage devices and the network. This paper presents our system architecture;one that is scalable in terms of the number of supported users and the throughput.

This paper examines the requirements for a large multimedia storage system, such as one for a movie-on-demand service. It presents the architecture for a storage system based on these requirements. The paper then presents a scheme for the organization, placement, and retrieval of multimedia data from the server. The data organization and retrieval schemes are analyzed and it is shown that their performance is superior to other schemes found in the literature.

With support from four NSF awards we aim to develop a prototype digital library in computer science and apply it to improve undergraduate educations. First, Project Envision, `A User- Centered Database from the Computer Science Literature,' 1991-94, deals with translation, coding standards including SGML, retrieval/previewing/presentation/browsing/linking, human-computer interaction, and construction of a partial archive using text and multimedia materials provided by ACM. Second, `Interactive Learning with a Digital Library in Computer Science,' 1993-96, supported by NSF and ACM with additional assistance from other publishers, focuses on improving learning through delivery of materials from the archive. Third, `Networked multimedia File System with HyTime,' funded by NSF through the SUCCEED coalition, considers networking support for distributed multimedia applications and the use of HyTime for description of such applications. Fourth, equipment support comes from the Information Access Laboratory allotment of the `Interactive Accessibility: Breaking Barriers to the Power of computing' grant funded by NSF for 1993-98. In this paper we report on plans and work with digital video relating to these projects. In particular we focus on our analysis of the requirements for a multimedia digital library in computer science and our experience with MPEG as it applies to that library.

FLOW SYNCHRONIZATION PROTOCOL

引用

IEEE-ACM TRANSACTIONS ON networking 1994年第2期2卷 111-121页

作者： ESCOBAR, J PARTRIDGE, C DEUTSCH, D STANFORD UNIV STANFORDCA 94305

We present an adaptive how synchronization protocol that permits synchronized delivery of data to and from geographically distributed sites. Applications include inter-stream synchronization, synchronized delivery of information in a multisite conference, and synchronization for concurrency control in distributed computations. The contributions of this protocol in the area of flow synchronization are the ability to synchronize over arbitrary topologies, the introduction of an adaptive synchronization delay, the flexibility to maintain multiple synchronization groups, and the use of a modular architecture that permits the application to tailor synchronization calculations to its service requirements. We take advantage of network protocols capable of maintaining network clock synchronization in the millisecond range.

An interactive system designed for talking via multimedia presentation with other parties on Ethernet- LAN is proposed. Our multimedia Chatting System will take several media services into consideration, like still image, text, pen writing, voice, and slow-motion video, to integrate a practical chatting system. The prototyping subsystem to implement the above idea is currently under development using NETBIOS communication interface and Microsoft Windows environment.

In this paper, the design model and implementation of an interactive PC system for creation and presentation of continuous media (CM) streams will be described. An object-oriented approach was used for defining the high-level abstractions of CM streams as well as the abstractions for grouping of related streams. The synchronization of multiple streams was performed by another abstraction known as logical time system. The system was implemented on a personal computer running under MS-DOS in C++ and is toolkit independent. The main contribution of this work is the integration of different abstractions in a single object-oriented model which allows suitable interactive manipulation with CM streams.

Evaluation of multimedia synchronization techniques

Proceedings of the International conference on multimedia computing and Systems

ISBN: (纸本)0818655305

This paper presents a classification of the multimedia synchronization techniques used to control jitter among media streams. The inter-media synchronization techniques are described in regard to their topology. Two major classes of multimedia synchronization techniques are then introduced as being distributed or local. Distributed schemes are used in networking environments. Local schemes are used within a workstation. An overview of some of the more well known synchronization techniques is then provided with a concentration on the distributed schemes. An evaluation of all the techniques follows with noted advantages and disadvantages.
