    Abstract:

    With the emergence of information-centric networking (ICN) in which in-networking caching distinguishes it from other Internet architecture, efficient caching becomes increasingly attractive, but remains of great challenge as current Web caching. This paper proposes a distributed scheme that is embedded with a locally central model, called APDR (i.e., content-aware placement, discovery and replacement). In APDR, according to the information carried on Interest message, the destination of the Interest makes caching decision for the nodes along the path, including different time that the requested content will be cached in different nodes. Finally, the study evaluates the proposed scheme through extensive simulation experiments in terms of a wide range of performance metrics. The experiment results show that the scheme can yield a significant performance improvement over diverse operating environments, such as, cache hit ratio, average access cost, number of replacement, forwarding efficiency and cache robustness etc. At the same time, additional overhead of APDR is small.
