Get NFD Connected

The Named Data Networking (NDN) Project offers a potential future Internet architecture designed as a distribution network.

The last post described how to deploy the NDN Forwarding Daemon (NFD) on a low-end box. This post describes how to get it connected.

The procedures and experiences in this post apply to any NDN node. If you aren’t using a low-end box, you may follow the official guide to install binary packages or compile from source. This post assumes you have ndn-cxx, nfd, and ndn-tlv-ping installed. You need access to two machines with NFD running; referred to as “local” and “remote”.

Connect to Another Machine

After installing NFD on your machine, you can connect to any other machine running NFD. Although NDN can run natively above Ethernet, there isn’t a global scale native NDN network yet because NDN is still in its early stage. Instead, NDN can run as an overlay network on top of a traditional IP network. You can specify the IP address and port number of the remote NFD, so that NDN packets get encapsulated into UDP or TCP packets and sent to the remote NFD.

To establish a connection, enter the following command:

What is NDN?

The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths — and address weaknesses — of the Internet’s current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. The project studies the technical challenges that must be addressed to validate NDN as a future Internet architecture: routing scalability, fast forwarding, trust models, network security, content protection and privacy, and fundamental communication theory. The project uses end-to-end testbed deployments, simulation, and theoretical analysis to evaluate the proposed architecture, and is developing specifications and prototype implementations of NDN protocols and applications. NDN Technical Report NDN-0001 Named Data Networking (NDN) Project is a slightly modified version of the NDN project proposal. The NDN project was funded by NSF in September 2010 as one of the four projects under NSF’s Future Internet Architecture Program.
