https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227303 Richard Scheffenegger <rscheff@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |In Progress --- Comment #8 from Richard Scheffenegger <rscheff@freebsd.org> --- The partial fix is D21798 / rS355269. That takes care of "unbounded" growth= of cwnd when the transmit side is application rather than cwnd limited. So cwnd only grows, if it is actually restricting the transmission rate. In order for cwnd to decay over time, when an session becomes app-limited a= nd the app keeps on sending small amounts of data to never enter after_idle, w= ill mean implementing New Congestion Window Validation (RFC7661). --=20 You are receiving this mail because: You are the assignee for the bug.=
