The Impact of Chunk Size on Named Data Networking Performance
Christos Nasis, Christos-Alexandros Sarros, Vassilis Tsaoussidis · 2020
Internet usage has evolved during the years towards accessing content, regardless of its location. The Named Data Networking architecture was designed to satisfy that need and replace today's host-centric TCP/IP stack by placing named content at the core of the architecture. In this paper, we provide the first evaluation specifically targeting the impact of packet size in NDN performance. Our results show the impact of chunk sizes is far from negligible; it clearly affects NDN performance as measured by metrics such as throughput, delay, cache hits and cache entry lifetime. Attention should, therefore, be given to the selection of an appropriate chunk size in NDN deployments.
