摘　　要：研究了美国下一代互联网协同应用环境Internet2Commons框架中的大规模分布式视频 会议应用服务的体系结构和关键技术,介绍了Internet2基于H.323协议的视频会议系统及正在其上 开展的各种应用,分析和总结了下一代互联网大规模视频协同环境的特点及向新一代IPv6网络迁移 的策略。Internet2 Commons is a next generation application framework that encourages deployment of tools for large scale distributed collaborative environment for the research and education community in U.S. The general architecture of design and managing large-scale, distributed videoconference collaborative environment was proposed. Key techniques of H 323-based videoconference system in Internet2 Commons were studied. Ordinary videoconference applications and special videoconference-based applications developed on Internet2 were also introduced. Migration policies of videoconference application from IPv4 network to IPv6 testbed were analyzed and Conclusions were given.
