Overview[1]#

Application-Layer Protocol Negotiation (ALPN) is defined in RFC 7301 as a Transport Layer Security (TLS) TLS extension for application layer protocol negotiation.

Application-Layer Protocol Negotiation allows the Application Layer to negotiate which protocol should be performed over a secure connection in a manner which avoids additional round trips and which is independent of the Application Layer protocols.
