为了有效地应对互联网上爆炸性增长的多媒体应用，大规模的流媒体系统必须充分考虑安全性、服务质量(Qos)、可扩展性和异构性问题。然而，当前的流媒体解决方案并不能同时解决所有这些挑战。针对这一局限性，本文提出了一种安全高性能的流媒体系统TrustStream，它结合了可伸缩编码、内容分发网络(CDN)和对等网络(P2P)的优点，在统一的架构下同时实现了前所未有的安全性、可伸缩性、异构性和一定的服务质量。在该体系结构中，原始视频被编码为两层，即基本层和增强层，基本层包含最关键的媒体内容，通过具有CDN特征的单源多接收器(S-M)P2P网络传输，以保证最低水平的质量；增强层，在纯多源多接收器(M-M)P2P框架中传输，以实现最大的可扩展性和带宽利用率。因此，通过仅提供接收方能够管理的层来解决异构性。在我们提出的S-M P2P拓扑结构下，通过将密钥分发机制和密钥嵌入方案相结合来提供安全性。我们已经在互联网上实现了TrustStream系统。由中国最大的CDN提供商中国高速缓存部署，TrustStream已经在互联网上直播了几个流行的视频节目。实验结果证明了该体系结构和系统的优越性和有效性。
To effectively address the explosive growth of multimedia applications over the Internet, a large-scale media streaming system has to fully take into account the issues of security, quality of service (QoS), scalability, and heterogeneity. However, current streaming solutions do not address all these challenges simultaneously. To address this limitation, this paper proposes a secure and high-performance streaming system called TrustStream, which combines the best features of scalable coding, content distribution network (CDN) and peer-to-peer (P2P) networks to achieve unprecedented security, scalability, heterogeneity, and certain QoS simultaneously under a unified architecture. In this architecture, raw video is encoded into two layers, namely, the base layer, which contains the most critical media content and is transmitted through a CDN-featured single-source multi-receiver (S-M) P2P network to guarantee a minimal level of quality, and the enhancement layer, which is transmitted in a pure multisource multi-receiver (M-M) P2P framework to achieve maximum scalability and bandwidth utilization. Heterogeneity is therefore addressed by delivering only the layers that a receiver is able to manage. Security is provided by combining our key distribution mechanism and key-embedding scheme under our proposed S-M P2P topology. We have implemented TrustStream system over the Internet. Deployed by ChinaCache, the largest CDN provider in China, TrustStream has broadcasted several popular live video programs over the Internet. The experimental results demonstrate the advantages and effectiveness of our architecture and system.
