EAGER: Telehealth and Wellness for Senior Citizens Utilizing In-Home Gigabit HD Multipoint Videoconferencing

高清多点视频会议是千兆和更快网络的核心应用。为10兆比特和更慢的网络设计的商业系统采用昂贵的会议桥，这些会议桥必须进行管理，限制并发视频会议的数量，并限制视频的质量。在这个研究项目中，端点发现和交换它们的能力，并确定它们之间的可用网络带宽，以协商最佳质量视频会议的参数。由于视频会议直接在两个或多个端点之间建立，因此该解决方案是可扩展的。由于不使用会议桥，因此该解决方案价格实惠。通过利用千兆位或更快的网络带宽，端点可以发送比当前系统提供的质量更高的压缩视频或未压缩视频。在支持GENI的网络中，第2层路由用于增加有效带宽，GENI切片用于增强隐私。凯斯西储大学的千兆光纤到户研究项目凯斯连接区（Case Connection Zone）正在演示如何使用千兆网络来改善包括健康和保健在内的几个国家优先领域居民的生活质量。 下一代高清多点视频会议是多项计划的重要工具。 在大约200个老年人住宅中，它使老年人能够足不出户地咨询临床医生，参加慢性病支持小组、社会团体和终身学习。许多千兆应用程序将采用这种技术或建立在它的基础上。

High-Definition Multipoint Videoconferencing is a core application for Gigabit and faster networks. Commercial systems, designed for 10 megabit and slower networks, employ expensive conferencing bridges that have to be managed, limit the number of concurrent video conferences, and limit the quality of the video. In this research project, the endpoints discover and exchange their capabilities and determine the usable network bandwidth between them to negotiate parameters for the best quality video conference. Since the video conferences are established between two or more endpoints directly, the solution is scalable. And since no conferencing bridge is used, the solution is affordable. By taking advantage of the Gigabit or faster network bandwidth, the endpoints can send reduced-compression video or uncompressed video that is higher quality than that offered by current systems. In GENI-enabled networks, layer 2 routing is used to increase effective bandwidth and GENI slices are used for enhanced privacy.The Case Connection Zone, a Gigabit fiber-to-the-home research project of Case Western Reserve University, is demonstrating how the Gigabit network can be used to improve quality of life for the residents in several national priority areas, including health and wellness. Next generation HD multipoint video conferencing is an essential tool for several initiatives. In about 200 senior residences, it enables seniors, without leaving home, to consult clinicians, participate in chronic disease support groups, in social groups, and in lifelong learning. Many Gigabit applications will incorporate this technology or be built upon it.
