信息中心网中移动性缓存策略研究

Survey of mobility cache strategy in information-centric networks

信息中心网络已经成为下一代网络体系结构研究的热点,ICN架构的典型特征就是利用内置缓存来提高内容的传播效率。随着移动用户数量的不断增加,未来移动用户也将访问ICN网络,因此开展ICN网络移动场景下的缓存研究是十分有意义的。在介绍了ICN网络后,接着从多方面着重介绍支持移动性缓存的方案,随后对ICN网络中传统缓存方案与移动性缓存方案进行比较和归纳,最后对移动性缓存方案的发展与挑战进行展望,为移动性缓存后续研究提供有益参考。

Information-Centric Networking（ ICN） has become a hotspot in the research of next-generation network architecture. The typical feature of ICN is to use built-in cache to improve the propagation efficiency of content. With the increasing number of mo-bile users, future mobile users will also visit the ICN network, so the ICN network cache study under mobile scenarios is very meaningful. After introducing the ICN network, the scheme of mobility support caching is introduced, and then the traditional cache scheme and mobility cache scheme in ICN network are compared and summarized. Finally, the development and challenge of mo-bile cache scheme are prospected, for the follow-up study of mobile cache to provide a useful reference.
