tcpEStatsPathPreCongSumCwnd
Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPathPreCongSumCwnd
OID (numeric): 1.3.6.1.2.1.156.1.1.4.1.23
Node type: OBJECT-TYPE
Type: ZeroBasedCounter32
Access: read-only
Description: The sum of the values of the congestion window, in octets, captured each time a congestion signal is received. This MUST be updated each time tcpEStatsPerfCongSignals is incremented, such that the change in tcpEStatsPathPreCongSumCwnd divided by the change in tcpEStatsPerfCongSignals is the average window (over some interval) just prior to a congestion signal.
What is tcpEStatsPathPreCongSumCwnd?
Running sum of the congestion window value captured just before each congestion signal; dividing its change by the change in tcpEStatsPerfCongSignals gives the average cwnd right before congestion hits, useful for seeing how large the window typically grows before backing off.
