Thank you very much! ---Original Message----- From: Cake <[email protected]> On Behalf Of John Sager Sent: Tuesday, February 23, 2021 6:15 AM To: [email protected] Subject: Re: [Cake] Enforcing video quality question
Here is the toy QoS solution for linux, which is a simplified version of the one I uses successfully on my home network. It uses quite a few scheduler modules - sch_htb, act_connmark, em_meta etc - that may not load automatically, so they may need to be listed in /etc/modules. Toke, thanks for agreeing to let the attachment through. John On 19/02/2021 19:04, John Sager wrote: > Yes.
