摘　　要：结合PKI、DRM和基于应用层的物理网络拓扑探测技术,提出安全可控的智能节点弹性重叠网络流媒体分发模型,解决系统各节点间的信任问题以及媒体资源的版权认证问题,并改进系统覆盖网络拓扑结构,使之符合底层物理网络拓扑,从而减少底层承载网络的流量,提高系统的传输效率,为Internet用户、内容提供商、网络运营商提供一个安全、可控、可管理、可运营的P2P技术解决方案。Integrating the technology of PKI, DRM and topology detection of physics layer network based on application layer, this paper presents the secure and governable streammedia transmission model based on intelligent node flexibility overlap network. It solves the problems of system trust and copyright authentication of media resource, and improves the system overlay topology structure. This model makes overlay topology accord the lower physics network topology structure, reduces the flux of lower transport network and improves the system transmit efficiency. It puts forward a secure, governable, administrable, manageable implementation scheme for Internet users, Internet service providers and content providers.
