-Subject: [PATCH] tcp_cubic: better follow cubic curve after idle period
-
-Jana Iyengar found an interesting issue on CUBIC :
-
-The epoch is only updated/reset initially and when experiencing losses.
-The delta "t" of now - epoch_start can be arbitrary large after app idle
-as well as the bic_target. Consequentially the slope (inverse of
-ca->cnt) would be really large, and eventually ca->cnt would be
-lower-bounded in the end to 2 to have delayed-ACK slow-start behavior.
-
-This particularly shows up when slow_start_after_idle is disabled
-as a dangerous cwnd inflation (1.5 x RTT) after few seconds of idle
-time.
-
-Jana initial fix was to reset epoch_start if app limited,
-but Neal pointed out it would ask the CUBIC algorithm to recalculate the
-curve so that we again start growing steeply upward from where cwnd is
-now (as CUBIC does just after a loss). Ideally we'd want the cwnd growth
-curve to be the same shape, just shifted later in time by the amount of
-the idle period.
