Since 2006, we designed and implemented a hybrid CDN-P2P live video streaming system, LiveSky, commercially deployed by ChinaCache. LiveSky has been used for live broadcasting of several large-scale nationwide events in China, e.g. broadcasting 2007/2008/2009 CCTV Spring Evening, 2008 Beijing Olympics, and so on. Furthermore, we proposed a secure and high-performance streaming architecture, TrustStream, which combines the best features of scalable coding, CDN and P2P, and key management scheme to achieve security, scalability, heterogeneity, and certain QoS simultaneously under a unified architecture. In our institute, the Special Interest Group of live video streaming system (SIGLIVE) is now working on the modeling, measurement and evaluation of large-scale live video streaming system and the key technologies and issues of hybrid CDN-P2P architecture.
