This article introduces the new L4S standard (RFC 9331) for addressing Internet congestion issues, specifically, buffers on networking devices. It appears to be a congestion notification mehcanism. Presumably it is superior to the queuing algorithms implemented on routers. My OpenWRT router, for example, offers a choice of queuing algorithm.
