Routing and Forwarding in nTorrent using ndnSIM

TL;DR

This paper explores implementing the nTorrent peer-to-peer file sharing application within the ndnSIM simulator to analyze how routing and forwarding strategies impact its performance in a data-centric networking environment.

Contribution

It demonstrates how to port nTorrent onto ndnSIM and investigates the effects of different routing and forwarding mechanisms in an NDN-based P2P file sharing context.

Findings

Routing strategies significantly affect data dissemination efficiency.

Forwarding mechanisms influence network load and latency.

Simulation results provide insights into optimizing NDN-based P2P applications.

Abstract

BitTorrent is a popular communication protocol for peer-to-peer file sharing. It uses a data-centric approach, wherein the data is decentralized and peers request each other for pieces of the file(s). Aspects of this process is similar to the Named Data Networking (NDN) architecture, but is realized completely at the application level on top of TCP/IP networking. nTorrent is a peer-to-peer file sharing application that is based on NDN. The goal of this project is to port the application onto ndnSIM and illustrate the effects of routing and forwarding.
