ViDe.Net: Middleware for Scalable Video Services for Research and Higher Education

这个多机构项目的重点是视频会议客户和服务与NMI中间件标准、功能和服务的新颖整合。其结果将是一个视频会议应用程序目录，能够对跨越机构组织边界的呼叫进行安全的域间身份验证。将建立一个视频中间件试验台，以测试该体系结构、其使用多个产品的实现以及这些产品的互操作性。试验台的结果将以视频中间件“食谱”的形式提供给高等教育和研究机构。该项目确定了4个目标。-开发用于H.323、SIP、MPEG2、VRVS和Access Grid实施的NMI Release 1通信对象类-开发视频会议安全要求规范的框架-开发用于部署和测试中间件、可互操作的视频会议服务的试验台。-通过包括视频中间件Cookbook在内的会议和出版物传播结果。该建议基于建立Vide.Net的丰富经验。Vide.Net是面向高等教育的国际视频会议服务。随着全球互联网成为真正的多服务基础设施，互联网视频会议在整个教育领域的使用将会增加，包括K-12。通过安全、易于使用的界面查找和连接资源的能力将使这项技术能够更多地使用，以加强课堂教学并克服地理和经济上的劣势。

The multi-institutional project focuses on a novel integration of video conferencing clients and services with NMI Middleware standards, functions and services. The outcome will be a videoconferencing application directory enabling secure, inter-domain authentication for calls that transit institutional organizational boundaries. A testbed for video middleware will be established to test the architecture, its implementation using multiple products, and the interoperability of these products. Testbed results will be provided to the higher education and research community in the form of a video middleware "cookbook". The project has identified 4 goals. - develop the NMI Release 1 communications object class for use in H.323, SIP, MPEG2, VRVS and Access Grid implementations - develop a framework for specification of videoconferencing security requirements - develop a testbed to deploy and test middleware-ware, inter-operable videoconferencing services.- disseminate the results through conferences, publications including a Video Middleware CookbookThe proposal is based on substantial experience building ViDe.Net, the international videoconferencing service for higher education. As the global internet becomes a true multi-service infrastructure, use of internet videoconferencing will increase throughout education, including K-12. The ability to look up and connect to resources through secure, easy-to-use interfaces will enable greater use of this technology to enhances classroom instruction and overcome geographic and economic disadvantage.
