[Bloat] FQ-PIE kernel module implementation

2015-06-04 Thread Hironori Okano -X (hokano - AAP3 INC at Cisco)
Hi all, I’m Hironori Okano and Fred’s intern. I’d like to let you know that I have implemented FQ-PIE as a linux kernel module “fq-pie and iproute2 for fq-pie. This was done in collaboration with others at Cisco including Fred Baker, Rong Pan, Bill Ver Steeg, and Preethi Natarajan. The source

What about the link type? If there are extra overheads going on, that's going to muck with the calculations (possibly adding latency, but shouldn't be cutting bandwidth), since the throttling calculations will be wrong. His ISP may be able to help with that. It would be interesting to see what

On ubuntu 14.04, I add a file named 10-debloat.conf in /etc/sysctl.d with the following lines in it: jg@thinkpad:/etc/sysctl.d$ cat 10-debloat.conf net.ipv4.tcp_ecn=1 net.core.default_qdisc=fq_codel On Thu, Jun 4, 2015 at 4:35 PM, Jonathan Morton chromati...@gmail.com wrote: The main one on

I think he may be seeing a complex interaction of various different queue components and bottlenecks, which in total manages to confuse TCP congestion control sufficiently to cause reduced throughput. I suspect that there is a shaper at the ISP end which limits the bandwidth available to any
