Packet drop analysis on NDN's content distribution, case study: Palapa ring topology

Abstract

This paper will report the research about packet drop in NDN, especially those influenced by the distribution pattern of the delivery of interest and packet data from consumer to producer and vice versa. Packet drop that is too large will make packet delivery and data not run well because the interest in upstreams by the consumer can not be received back to the consumer as a packet data. NDN is a network architecture based on content named that will replace the function of IP technology, especially in networks that have topology in large scale. Simulation using NDNSim and topology using Palapa Ring, to examine the effect of packet drop, especially with the application of distribution method. The results conclude that using of Zipf Mandelbrot distribution pattern, can reduce the most significant packet drop probability compared to use of random distribution, The next sequence is on using of Exponential distribution patterns, but using uniform distribution, no reduction of packet drop probability in comparison with scenarios using random distribution.
