This memo proposes a new Datagram Transport Transport Layer Security (DTLS) extension for DTLS 1.2 that provides the ability to negotiate, during handshake, a transport independent identifier that is unique per security association. This identifier effectively decouples the DTLS session from the underlying transport protocol, allowing the same security association to be migrated across different instances of the same transport, or to a completely different transport.
