Goal

How does the DSR behave while in "proving mode" for a connection?
 

Solution

Here is the expected behavior of the DSR in relation to proving mode.

First when it will enter the proving state:

Based on configuration the DSR will enter the "Established-Proving" connections state when:
a. Immediately after successful completion of capability exchange (proving mode = always or suspect)
b. Most recent connection failure that was not initiated by a DPR from local MP or DPR from peer (proving mode = suspect)


then what it will do while in the proving state and DWA is received:


While in the “Established-Proving” connection state, if a DWA is received from the peer, before Tprv times out, then DSR will do the following:
¨ Stop Tprv;
¨ Set ConsecutiveTprvTimeouts to zero;
¨ Increment ConsecutiveDwxExchanges;
¨ If ConsecutiveDwxExchanges == Proving Times;
○ Transition to the "Established-Available” connection state.
¨ Else:
○ Send DWR;
○ Start Tprv.

and what it will do while in the proving state and DWA is NOT received:


During an active proving phase, if Tprv times out then DSR will do the following:
¨ Set ConsecutiveDwxExchanges to zero
¨ Increment ProvingRestarts
¨ Increment ConsecutiveTprvTimeouts
¨ If (ProvingRestarts == 3) OR (ConsecutiveTprvTimeouts == 3):
○ Close connection
○ Transition to connecting/listening connection state
  -Else
  ○ RestartProving
