+## Retry and Version Negotiation
+
+A Retry or Version Negotiation packet causes a client to send another Initial
+packet, effectively restarting the connection process and resetting congestion
+control and loss recovery state, including resetting any pending timers.  Either
+packet indicates that the Initial was received but not processed.  Neither
+packet can be treated as an acknowledgment for the Initial.
+
+The client MAY however compute an RTT estimate to the server as the time period
+from when the first Initial was sent to when a Retry or a Version Negotiation
+packet is received.  The client MAY use this value to seed the RTT estimator for
+a subsequent connection attempt to the server.
