There has been recent significant activity with the cake qdisc of late but in the cobalt branch. Some of that effort is related to upstreaming to kernel & iproute2 mainline but we're not quite there yet. Relevant feature changes: ingress mode: Instead of only counting packets that make it past the shaper, include packets we've decided to drop as well, since they did arrive with us on the link and took link capacity. This mode is more suitable for shaping the ingress of a link (e.g. from ISP) rather than the more normal egress. ptm mode: Minor optimisation in packet overhead calculation. dual-src/dsthost/triple-isolate: Optimise only calculating src or dst host hashes only if required. ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in highly assymetric links (downstream v upstream capacity) where the majority of upstream link capacity is occupied with ACKS for downstream traffic. A separate iproute2 patch to teach it about Cake's new features will follow. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> |
