Named Data Networking Daemon

NDNd is a Golang implementation of the Named Data Networking (NDN) protocol stack.

See the project overview, architecture details and the tutorial for more info on NDN.

🏗️ Installation

Pre-built static binaries for all supported platforms are available on the releases page. Linux-based systems may also utilize the provided Docker images.

NDNd is written in pure Go and requires Go 1.23 or later to build from source. Once Go is installed, run make to build the ndnd executable, followed by make install to install it globally.

🌟 Usage

NDNd provides several independent modules that can be used separately or together.

You can use the ndnd CLI to list available modules and get more info on their usage. A tutorial example for running a simple NDN network can be found here.

🔀 Network Forwarder

The ndnd/fw package implements YaNFD, a packet forwarder for the NDN platform. It is compatible with the management tools and protocols developed for the NFD forwarder.

To start the forwarder locally, run the following:

ndnd fw run yanfd.config.yml

A full configuration example can be found in fw/yanfd.sample.yml. Note that the default configuration may require root privileges to bind to multicast interfaces.

Once started, you can use the forwarder control tool to manage faces and routes.

📡 Distance Vector Router

The ndnd/dv package implements ndn-dv, an NDN Distance Vector routing daemon.

To start the routing daemon bound to the local forwarder, run the following:

ndnd dv run dv.config.yml

A full configuration example can be found in dv/dv.sample.yml. Make sure the network and router name are correctly configured and the forwarder is running.

Once started, you can use the router control tool to create and destroy neighbor links.

📚 Standard Library

The ndnd/std package implements go-ndn, a standard library for NDN applications.

You can use this package to build your own NDN applications. Several examples are provided in the std/examples directory.

The standard library supports the Light VerSec binary format for trust schema specification.

🛠️ Tools

The ndnd/tools package provides basic utilities for NDN networks. These can be used directly using the ndnd CLI.

• sec: security utilities for generating keys and certificates (docs)
• certcli: interactive NDNCERT client (docs)
• ping/pingserver: test reachability between two NDN nodes
• cat/put: segmented file transfer between a consumer and a producer
