   tc-cake    ( 8 )

расширенные общие приложения (CAKE) (Common Applications Kept Enhanced (CAKE))

OTHER PARAMETERS

memlimit LIMIT Limit the memory consumed by Cake to LIMIT bytes. Note that this does not translate directly to queue size (so do not size this based on bandwidth delay product considerations, but rather on worst case acceptable memory consumption), as there is some overhead in the data structures containing the packets, especially for small packets.

By default, the limit is calculated based on the bandwidth and RTT settings.

wash

Traffic entering your diffserv domain is frequently mis- marked in transit from the perspective of your network, and traffic exiting yours may be mis-marked from the perspective of the transiting provider.

Apply the wash option to clear all extra diffserv (but not ECN bits), after priority queuing has taken place.

If you are shaping inbound, and cannot trust the diffserv markings (as is the case for Comcast Cable, among others), it is best to use a single queue "besteffort" mode with wash.

split-gso

This option controls whether CAKE will split General Segmentation Offload (GSO) super-packets into their on-the-wire components and dequeue them individually.

Super-packets are created by the networking stack to improve efficiency. However, because they are larger they take longer to dequeue, which translates to higher latency for competing flows, especially at lower bandwidths. CAKE defaults to splitting GSO packets to achieve the lowest possible latency. At link speeds higher than 10 Gbps, setting the no-split-gso parameter can increase the maximum achievable throughput by retaining the full GSO packets.
