Refine RTO Parameter

After an association is established, the EAGLE pass command should be used to get the true RTT as experienced by the association.

1. Reset the counters: pass:loc=XXXX:cmd=“assocrtt –r <assoc name>".
2. Wait a reasonable interval (preferably 24 hours) before collecting the measurements: pass:loc=XXXX:cmd=“assocrtt <assoc name>".
3. Perform the sctp –g pegs or sctp –a assocname command to determine if any retransmissions have occurred.
4. Use the values reported to further tune RMIN and RMAX. Use the Weighted Average RTT in this case for defining RMIN.
