tcpEStatsPathNonRecovDAEpisodes
Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPathNonRecovDAEpisodes
OID (numeric): 1.3.6.1.2.1.156.1.1.4.1.2
Node type: OBJECT-TYPE
Type: ZeroBasedCounter32
Access: read-only
Description: The number of duplicate acknowledgment episodes 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 number of times the 'dupacks' counter is set to zero when it is non-zero but less than RetranThresh.
Note that the change in tcpEStatsPathNonRecovDAEpisodes divided by the change in tcpEStatsPerfDataSegsOut is an estimate of the frequency of data reordering on the forward path over some interval.
What is tcpEStatsPathNonRecovDAEpisodes?
Count of duplicate-ACK episodes that resolved on their own, the ACK advanced, before enough dup-ACKs arrived to trigger Fast Retransmit; dividing its rate of change by tcpEStatsPerfDataSegsOut estimates how often the forward path reorders data rather than truly losing it.
