This is not quite true any longer. Linux implements RACK-TLP (RFC8985) which prevents short-term reordering (such as that caused by ECMP) from being interpreted as a congestion event. It seems Windows does too, these days: https://techcommunity.microsoft.com/blog/networkingblog/algorithmic-improvements-boost-tcp-performance-on-the-internet/2347061 -Toke _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/3IRDUGJTO4HTIZHHLUVYQJC6E2PCPPRT/
