SBIR Phase I: Micro-Cloud Managed Web-based Peer-to-Peer Video Streaming

该创新提出并发展了微云管理的基于Web的点对点视频流媒体新技术。该技术承诺以传统内容交付网络(CDN)十分之一的成本实现高度可扩展、强大和安全的互联网视频流(包括现场视频和视频点播)。视频流量正以每年52%的速度爆炸性增长。与此同时，观众对体验质量(QOE)的要求也越来越高，要求实时、高清无缝接入。为了应对即将到来的互联网视频流量浪潮，这项创新提供了五个独特的优势：(1)微云管理的P2P流媒体使用了一套新颖的算法来持续实时优化每位观众的QOE，可以显著超过传统的非托管P2P流媒体解决方案(特别是在压力下)。(2)与传统CDN相比，带宽和服务器资源消耗降低了10倍。(3)提供实时观众分析，可快速定位性能瓶颈并从中恢复。(4)与传统的对等软件不同，解决方案客户端库完全基于Web。因此，它不需要安装软件/插件，并且可以跨多个平台无缝工作。(5)该技术为内容保护和数字版权管理提供了强有力的支持。更广泛的/商业影响包括以下两个主要方面。(1)商业影响。该解决方案旨在将一项颠覆性技术引入互联网视频分发市场，该市场的收入正以每年40.6%的速度快速增长。这项技术可以使广泛的客户群受益，包括内容发行商、社交媒体网站、企业和互联网服务提供商。(2)社会影响。在互联网上以低成本获得高质量的视频可能会产生重大的社会影响。原本负担不起基于CDN的传统视频交付系统的消费者现在可以在包括教育和协作在内的广泛社交活动中利用这一创新。

The innovation proposes and develops the novel technology of micro-cloud managed Web-based peer-to-peer video streaming. The technology promises to enable highly scalable, robust and secure Internet video streaming (including both live video and video-on-demand) at only one tenth of the cost of traditional content delivery networks (CDNs). Video traffic is growing explosively at an annual rate of 52%. Meanwhile, viewers place increasingly stringent requirements on their quality of experience (QoE), demanding seamless access in real time with high definition. To handle the coming wave of Internet video traffic, the innovation offers five distinctive advantages: (1) The micro-cloud managed peer-to-peer streaming uses a set of novel algorithms to continuously optimize the per-viewer QoE in real time and can significantly outperform traditional unmanaged peer-to-peer streaming solutions (especially under stress). (2) The technology achieves a 10x reduction in bandwidth and server resource consumption over traditional CDNs. (3) The solution provides real-time viewer analytics and can quickly pinpoint and recover from performance bottlenecks. (4) Unlike conventional peer-to-peer software, the solutions client library is completely Web-based. Hence it requires no software/plugin installation and works seamlessly across multiple platforms. (5) The technology provides strong support for content protection and digital right management.The broader/commercial impact consists of the following two main aspects. (1) Commercial impacts. The solution aims to introduce a disruptive technology in the Internet video distribution market, which is growing rapidly at an annual rate of 40.6% on revenue. The technology can benefit a broad customer base, including content distributors, social media sites, enterprises and Internet service providers. (2) Societal impacts. The availability of high-quality videos on the Internet at low cost can potentially generate significant societal impacts. Consumers who otherwise cannot afford the traditional CDN-based video delivery systems can now utilize the innovation in a wide range of societal activities including education and collaboration.
