Application-Layer Protocol Negotiation Labels for Session Traversal Utilities for NAT Usages
RFC 7443, “Application-Layer Protocol Negotiation Labels for Session Traversal Utilities for NAT Usages”, is an Informational document published in January 2015 by P. Patil, T. Reddy, G. Salgueiro, M. Petit-Huguenin. The canonical text is published by the RFC Editor.
Abstract
Application-Layer Protocol Negotiation (ALPN) labels for Session Traversal Utilities for NAT (STUN) usages, such as Traversal Using Relays around NAT (TURN) and NAT discovery, are defined in this document to allow an application layer to negotiate STUN usages within the Transport Layer Security (TLS) connection. ALPN protocol identifiers defined in this document apply to both TLS and Datagram Transport Layer Security (DTLS).
