The paper compares four different Linux qdiscs in a simple lab setup, and demonstrates bufferbloat, and the mitigation provided by fq_codel, quite well. The first couple of sections on how TCP and the Linux network stack work are probably known material to most people here, so feel free to skip to the experimental setup and results in sections 5 and 6. I hope you will find this interesting; feel free to comment and/or ask questions. :) =2DToke =2D-=20 Toke H=C3=B8iland-J=C3=B8rgensen toke@toke.dk --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQEcBAEBAgAGBQJQ+I4+AAoJEENeEGz1+utPf6MH/Rn6NAuxG+HguRevqMypR1o4 4hwrT8tlCWnyZ4+4sj28H+xjQCkLJCSqHZnc6ZW0ZknbbtSmEuR741tZ0SqTFfgK L6vqe6vOw85doH04JHNI+ymvcitGsS3N/XokuxZ0DTVA0fNzQoDu1vDET9/kOCP8 bXXAtSIxwqYD+tjU0GvHtw+KyAuxQIhJ5P88aR3ceNjsTjg1qUR28LVEtBQNbkSe Tjhn66nmqfzK16EK+aH0Q33uIqrwTMUuKEgepNKmwQBKYtNEJ05S0sdf2ut57PWs 7BjNmYNMUiXqF+OObfOoZK39miHePFk36z8fAXGmfgoUvdxTvZnMNJtCWfY594M= =4N3K -----END PGP SIGNATURE----- --=-=-=--
