Hello All,

Please excuse if this topic has been previously discussed.  I have a question about TCP Keep Alives.

Section 5 of draft-ietf-tls-tls13-11 reads:

"Three protocols that use the TLS Record Protocol are described in this document: the TLS Handshake Protocol, the Alert Protocol, and the application data protocol." 

Then continues with:

"Implementations MUST NOT send record types not defined in this document unless negotiated by some extension.  If a TLS implementation receives an unexpected record type, it MUST send an 
"unexpected_message" alert."

In the wild today, I see many TLS connections which use TCP Keep Alive (NOT TLS Heartbeat).   I take it that this will not work going forth?
 Thanks,

Nalini Elkins
