* [**NLSR** - Named-data Link-State Routing protocol](https://github.com/named-data/NLSR)
* [**ndn-tools** - Essential NDN command-line tools](https://github.com/named-data/ndn-tools)
* [**ndn-svs** - State Vector Sync library](https://github.com/named-data/ndn-svs)
* [**PSync** - Partial and full Sync library](https://github.com/named-data/PSync)
* [**ChronoSync** - Sync library for distributed real-time applications *(deprecated)*](https://github.com/named-data/ChronoSync)
* [**NAC** - Name-based Access Control library](https://github.com/named-data/name-based-access-control)
* [**NDNCERT** - NDN certificate management protocol](https://github.com/named-data/ndncert)
* [**repo-ng** - NDN repository implementation in C++ *(deprecated)*](https://github.com/named-data/repo-ng)
