NDN is one of five project funded by the National Science Fondation under its future internet Architecture Program. NDN has its roots in an erlier project, Conten-Centric Networking (CCN), which Van Jacobson first publicly presented in 2006. NDN has changed the paradigm of the communication network for sending a packet to the destination address by identifyng by name. NDN emphasizes content by making it directly addressable and routable. Endpoints communicate based on named data instead of IP addresses.

Introduction
• NDN is one of five project funded by the National Science
Fondation under its future internet Architecture Program.
• NDN has its roots in an erlier project, Conten-Centric
Networking (CCN), which Van Jacobson first publicly
presented in 2006.
• NDN has changed the paradigm of the communication
network for sending a packet to the destination address by
identifyng by name.
• NDN emphasizes content by making it directly addressable
and routable. Endpoints communicate based on named data
instead of IP addresses.

Research contributions
Contribution in this research is conducting a
simulation by creating a NDN scenarios and
implementing several different forwarding
strategies, in implementing that, in the
application of simulation using topology palapa
ring, scenarios and topologies created using a
simulator ndnSIM.

Research purposes & Problem
• Objectives of this research is performance
reviews strategy forwarding and understand the
delay characteristics in NDN.
• Which of the two major approaches of
forwarding strategies perform best when
measured by delay parameters.

Strategi Forwarding
• The bestroute strategy forwards an Interest to the
upstream with lowest routing cost.
• Using Retransmission suppresion interval.
• Min (100ms)  ndnSIMv2.
Bestroute
Broadcast
• The broadcast strategy forwards every Interest to all
upstreams, indicated by the supplied FIB entry.
• Iteration strategy  nexthop record  FIB.
• Interest will be broadcast to all upstream (eligible).

Delay on Consumer Node
Figure 6. Delay on Consumer Node using strategy bestroute Figure 7. Delay on Consumer Node using strategy broadcast
Consumer node graph displays delay resulting from the simulation for 5s,
10s, 25s and 50s delay with the display values that I owned every
consumer node during the simulation process, each time the simulation
produces different results depending delay of each consumer.
Based on the comparison on the two graphs above that, the consumer
using the broadcast strategy has less delay than the bestroute strategy.

12. [12]The 3rd
International Conference on Wireless and Telematics 2017
Based on NDN simulation, which has been conducted on the
topology of the palapa ring, shows that the measurement of the delay
of two strategies forwarding bestroute and broadcast have come to
the conclusion that the simulations which have been conducted by
using maximum time intervals for 50s, the bestroute delay is 65s
greater than broadcast delay 29s by a margin of 36s. it can be
concluded that if the simulation is conducted in a longer time, the
possibility of bestroute forwarding strategies will have a more delay
than the broadcast one, it shows that bestroute strategies are better
than broadcast when it is measured by the delay.
The future next project is how to minimize the delay for each
consumer.
