Caching Performance of Named Data Networking with NDNS

Named Data Networking, a future internet network architecture design that can change the network’s perspective from previously host-centric to data-centric. It can reduce the network load, especially on the server part, and can provide advantages in multicast cases or re-sending of content data to users due to transmission errors. In NDN, interest messages are sent to the router, and if they are not immediately found, they will continue to be forwarded, resulting in a large load. NDNS or a DNS-Like Name Service for NDN is needed to know exactly where the content is to improve system performance. NDNS is a database that provides information about the zone location of the data contained in the network. In this study, a simulation was conducted to test the NDNS mechanism on the NDN network to support caching on the NDN network by testing various topologies with changes in the size of the content store and the number of nodes used. NDNS is outperform compared to NDN without NDNS for cache hit ratio and load parameters.
