tcpEStatsStackAbruptTimeouts
Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsStackAbruptTimeouts
OID (numeric): 1.3.6.1.2.1.156.1.1.5.1.30
Node type: OBJECT-TYPE
Type: ZeroBasedCounter32
Access: read-only
Description: The number of timeouts that occurred without any immediately preceding duplicate acknowledgments or other indications of congestion. Abrupt Timeouts indicate that the path lost an entire window of data or acknowledgments.
Timeouts that are preceded by duplicate acknowledgments or other congestion signals (e.g., ECN) are not counted as abrupt, and might have been avoided by a more sophisticated Fast Retransmit algorithm.
What is tcpEStatsStackAbruptTimeouts?
Count of timeouts that occurred with no preceding duplicate ACKs or other congestion signal, meaning an entire window of data or ACKs was lost outright; distinguishes a sudden full-window loss from the more gradual loss patterns Fast Retransmit is designed to catch.
