Object
column RMON2-MIBZeroBasedCounter32
Duplicate acks (or SACKS) that did not trigger a Fast
Retransmit because ACK advanced prior to the number of
duplicate acknowledgments reaching RetranThresh.
In many implementations, this is the sum of the 'dupacks'
counter, just before it is set to zero because ACK advanced
without a Fast Retransmit.
Note that the change in tcpEStatsPathNonRecovDA divided by
the change in tcpEStatsPathNonRecovDAEpisodes is an
estimate of the average reordering distance in segments
over some interval.
