…n start only after the TCP handshake is complete. However, with TCP Fast Open [ RFC7413 ], the implementation can achieve the same RTT efficiency as DTLS. Note: DNS over DTLS is an experimental update to DNS, and the experiment will be concluded when the specification is evaluate…

…CP connection that was terminated, as discussed in [ RFC7766 ], TCP Fast Open [ RFC7413 ] is of benefit. Underlining the requirement for sending only encrypted DNS data on a DNS-over-TLS port ( Section 3.2 ), when using TCP Fast Open, the client and server MUST immediately initia…

…CP-based solutions may also seek performance through the use of TCP Fast Open [ RFC7413 ]. The cookies used in TCP Fast Open allow servers to correlate TCP sessions. TLS-based implementations often achieve better handshake performance through the use of some form of session resum…

…tes the TCP MD5 option. ¶ Unlike UDP, TCP without the TCP Fast Open extension [ RFC7413 ] does not support 0-RTT session resumption. The TCP user timeout [ RFC5482 ] equivalent for application data relayed by the TURN is the use of RTP control protocol (RTCP). As a reminder, RTCP…
