Effect of overhead flooding on NDN forwarding strategies based on broadcast approach

At this time forwarding strategy became the center of attention of researchers in area named data networking (NDN). This is because the forwarding strategy is responsible for managing every packet of interest received by the NDN router, then the characteristics of forwarding strategies will have a significant impact on NDN performance. Therefore this study aims to perform analysis using a large approach in forwarding strategy that is broadcast approach. It is expected that the results of this study can be utilized by researchers in the field of NDN to determine the direction of research. Parameter of study in this research is delay in observation time interval. A forwarding strategy using a broadcast approach is simulated in order to understand the NDN delay characteristics within the observation interval. The simulation of the research was conducted on the NDNSim simulator with several scenarios. From the simulation results obtained that cumulatively delay broadcast forwarding strategy in multi producer scenario there is no difference between fulldelay and lastdelay. However, in the single producer scenario there is a difference between fulldelay and lastdelay this can be influenced by the large number of consumers who send interest to the producer and also based on the flooding method of the interest package in order to find the nearest NDN router containing the expected content as soon as possible, So that it can overload the network performance and effects overhead.
