This is the networking daemons and networking backbone for Orion, all the applicative and bgp management are available on another repo: https://github.com/MatthieuCoder/Orion

This is a simple program called oriond that manages wireguard tunnels to other peers of the Orion network.

There is also a server program called registry that tracks all the Orion networks connections and all signaling between peers to archieve UDP-hole-punching and negociation between clients.
