Interactive Connectivity Establishment (ICE) Extensions protocol.
ICE specifies a protocol for setting up Real-Time Transport Protocol (RTP) streams in a way that allows the streams to traverse network address translation (NAT) and firewalls.
ICE uses protocols such as Simple Traversal of UDP through NAT (STUN) and Traversal Using Relay NAT (TURN) to establish and verify connectivity.
