摘要
未来互联网体系架构研究是科技发展的重大战略需求,命名数据网络(NDN)作为目前最为活跃的前沿建议方案,得到了国内外研究学者的重点关注。NDN体系架构颠覆了当前互联网的基础,仍有很多问题亟待解决。NDN内容分发机制是推动NDN实际发展的关键,但仍有很多研究问题尚未解决。重点介绍了NDN在内容分发方面的概念和模型;分析了NDN内容分发机制在转发策略、冗余控制、拥塞控制和访问控制4个方向面临的问题和当前国内外的研究进展,并针对上述问题提出思考。
Future interact architecture research is one of the major strategic needs of science and technology development. As a promising design, named data networking （NDN） has drawn the extensive attentions of researchers and industry. Since NDN architecture evolves the internet from today＇s host-based packet delivery towards directly retrieving named objects, there are still a lot of issues have yet to be studied. Its content distribution mechanisms are the key to promote the development and deployment. The concepts and characteristics of NDN content distribution were introduced. The current advances in the aspect of forwarding strategy, redundant control, congestion control and access control were emphasized. Aimed at the faced problems, some discussions and analysis were also presented.
