           Application-Layer Protocol Negotiation (ALPN) Labels          for Session Traversal Utilities for NAT (STUN) Usages


   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).
