ICE (Internet Connectivity Establishment) is a widely used standard for NAT (Network Address Translation) hole punching. If NAT hole punching fails, then TURN (Traversal Using Relays around NAT) can be used to relay data between peers.

librice is a sans-IO library that handles the intricacies of ICE and has recently gained support for communicating with TURN servers. We will discuss TURN and how it is implemented within librice.
