TCP Congestion Control in Windows 10 RRS feed

  • Question

  • Hi,

    my question refers to the default congestion control algorithm in Windows 10. Is Compund TCP (CTCP) enabled as the default TCP congestion control algorithm? Or is it sth else? What options are availbe in this context with Windows 10 and the upcoming server versions?

    Kind regards

    Tom

  • Hi Tom,

    Thank you for your question.

    By default, CTCP wasn’t configured in Window 10, we could run the following command:

    Netsh Interface Tcp  show global

    We could check the value of “Add-on Congestion Control Provider” is none. We could configure it into CTCP in CMD.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,

    Jim

  • Jim,

    Old answer; perhaps something has changed. I'm using Win10 1709. When I use the netsh command you recommend above, I see "default", not "none", for "Add-On Congestion ..."

    Is "none" the default?

    I see the info in your 2015-08-27 note below, "By default, CTCP wasn't configured in Window 10". Just confirming, please!

    Thanks in advance.
