Abstract

Content-Centric Networking (CCN) proposals rethink the communication model around named data. In-network caching and multipath routing are regarded as two fundamental features to distinguish the CCN from the current host-centric IP network. In this paper, we tackle the problem of joint collaborative caching and multipath routing in CCN. We achieve this with an online and offline combination caching scheme based on a local content popularity statistic results. Besides, we place the content heterogeneously along a path and resort to a caching aware dynamic multipath routing in a coordination fashion. The proposed scheme can increase the content diversity and improve the caching utility with the aim of minimizing the user access delay. Simulation experiments have been performed to evaluate the proposed scheme. Simulation results show that the proposed scheme is effective and outperforms the existing caching mechanisms in CCN.
