Comparison of Caching Replacement Policies in Changing the Number of Interest Packets on Named Data Networks Using Mininet-NDN

Named Data Networking (NDN) is a new concept of network architecture. Unlike TCP/IP which is based on IP addresses and each IP layer packet needs to travel end to end from source to destination address to get the requested content, NDN allows the process of requesting content to be a shorter journey due to a component called caching. With caching, the Content Store (CS) on the NDN router will be populated with the content requested by the consumer. This content retention mechanism is managed using caching policies, which are of two types, cache placement policies, and cache replacement policies. This study examines the performance of FIFO and LRU cache replacement policies for a certain number of interest packages based on parameters such as delay, packet loss, and throughput. This study uses nodes from the pan-European GEANT network topology in Mini-NDN, a Mininet-based network emulator for NDN. Tests using emulators provide research results that are close to real-world conditions. Based on the experiment, LRU has better performance than FIFO in handling the increase in data interest as seen from throughput and packet loss. However, in terms of average delay, FIFO is better than LRU.
