A New, Evolutive API and Transport-Layer Architecture for the Internet

NEAT supports FreeBSD, Linux, OS X and NetBSD

NEAT internals 🔩

NEAT is a callback based library and everything revovles around the neat_ctx struct. This struct has to be initialized before anything else can be done. NEAT uses libuv as event library, and this loop is available to users so that they can hook in and add their own callbacks.

One of the first things done in NEAT after the library has been initialized is to start monitoring the available addresses on all interfaces of the machine. NEAT supports multi-homing and we must therefore have an up-to-date view of the available (and connected) network resources available on a machine. Address events are published using an internal event API, which users also can hook into. It is useful if only a small subset of NEAT is wanted, for example monitoring the preferred lifetime of a v6 address. Look at neat_resolver.c for an example on how to use this API. An address is stored in a platform-independent structure.

After NEAT has been initialized, it is up to the user to do what he or she wants. A typical first step is to resolve a domain name.

Requirements ☝️

• cmake
• libuv (version 1.9 or later)
• ldns
• ljansson (version 2.7 or later)
• libmnl (linux only)
• libsctp-dev (linux only, for kernel SCTP support)
• swig (for generating Python bindings)

OS	Install Dependencies
Debian/Ubuntu*	apt-get install cmake libuv1-dev libldns-dev libjansson-dev libmnl-dev libsctp-dev swig
FreeBSD	pkg install cmake libuv ldns jansson swig30
OS X	brew install cmake libuv ldns jansson swig
* Ubuntu 15.04 and higher

Quickstart 🚀

$ cd <path-to-neat-src>
$ mkdir build && cd build
$ cmake ..
$ cmake --build .

This will generate makefiles and compile the library and the samples. You will find the shared and the static library in the build directory and the samples in build/examples directory. Note, that Python bindings are currently considered experimental and, therefore, have to be activated deliberately. To do so, change the first cmake call above to:

$ cmake .. -DSWIG_PYTHON=1

For an easy introduction to NEAT, have a look at our tutorial.

You may also look at neat_http_get.c in the samples directory for a practical example.

$ ./client_http_get www.neat-project.org

In order to (optionally) install the neat library simply run.

$ sudo make install

Don't forget to run ldconfig after installing neat the first time.
