Porting Caching Functions to Named Data Networking Forwarding Daemon (NFD)

The purpose of using the Internet has changed from "connecting to computers" to "acquiring content". So, the ICN (Information Centric Network) has been proposed to fit this purpose. In this research, we focus on the architecture of NDN (named data networking). The NFD (NDN forwarding daemon) is a network forwarder that implements the NDN protocol. The ndnSIM is a simulator of NDN. From ndnSIM version 2.8, a part of content store implementation has been removed from the simulator and it becomes to use content store implementation of NFD. In this poster, we select two caching functions, probabilistic caching and expired deletion, which are removed from ndnSIM 2.8 and not included in NFD. We port these functions to NFD for a more practical implementation. Under a certain network, we were able to confirm that previous and ported functions provided equivalent functions. It was also possible to simulate in version ndnSIM 2.8 using the ported functions.
