摘要
分布式视频服务(Distributed Video Service, DVS)系统为全球视频点播管理和分发提供了全面的解决方案。分布式交换机提供了一种可扩展的体系结构，通过可选的专用高速骨干网将互联网的全球可访问性与可接受的服务质量结合起来，并通过将电影分发到离潜在观众更近的服务器上。为了应对电影需求和服务器负载的动态变化，分布式交换机采用自适应算法进行服务器选择和电影分发。分布式交换机采用Java语言实现，集成前端播放软件，支持IP作为公网，支持ATM作为私网。
DVS: a system for distribution and management of global video on demand services
The Distributed Video Service (DVS) system provides a comprehensive solution for the management and distribution of global video on demand. DVS presents a scalable architecture that combines the global accessibility of the Internet with an acceptable quality of service through an optional private high-speed backbone, and by distributing movies off-line to servers that are closer to potential viewers. To cope with dynamic changes in movie demand and server load, DVS employs adaptive algorithms for server selection and for movie distribution. DVS was implemented in Java, integrated with a front-end playing software, and supports IP and ATM as the public and private networks, respectively.
