I have been an advocate of pacing during the first transmission burst = (including after an idle period) for quite some time, and also for = delay-based algorithms. There would be no need for AQM if TCPs would = maximize throughput while at the same time minimizing mean end to end = delay, which is a matter of choosing for cwnd the largest value that = maintains the smallest current RTT. Those Google folk are pretty smart. --Apple-Mail=_2F2C127A-A05E-4E2A-806E-8622F4E2B597 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="signature.asc" Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQIVAwUBVtdfi0ayAOS/EQ8MAQKvnA/8DM49rSfU8CFmh99YLIZ6EmBlIZosT9Aa EoEN5torIK4tcQ6mmZPuRMUGJamGn/BnFNtPomEOEff/zFZMoPn2x6sXGiiAF6Py uN+wXjoQ8dlRJHqWLSxwM6dOviflFNO1juABdn9pE4d6E9Pk/Cha7AufQ8hyt5mr FeAdWLPv3Bxi7yu6lF0ObO7kTW1w1YSqR3dCY2sqD76zujGHub562HE/WcpExElm HtBRBRnF1ApubRhKnx3vCsfYX8tc+kREjKfWY5ZgWdV+OvV/gFlwjEUbucfoYZjg u0iO1okv20X0rfbOlSNq+m7BeQUFbULQQ8dpYyvxRzX5IzCTkDty7O85r8OoXAJt XiHXn2hVYnKQ5pvDMDXyEUGXdrshfjM2QTGY+XIaaoow41OnrcrWjOiCZTM1YmeC KiX6wl+9q04WSahc5lDZy66dkmbBAqLLO42pU0AbuXWUzeJXrVcWWqYL2xabIvIf GUGTPjKUIo1Kg15OfkoxPe1pqkuwshxB/oXK2CbXQ8uf+hCi+9XeE+7EmeomhaMe tXhIb73QJPPo0tpfgFQ6F16mjK/a3FtVT2Dtaf74Bbakk0ZE1zcbIR/R8z3qN52C vhusEqimtmhMR0YoK12vHWWIVQiGHdlvgcTG0gdQPjLeVGHsbIhRb3u+D6cODwfa d+q0evcnHyk= =wjGD -----END PGP SIGNATURE----- --Apple-Mail=_2F2C127A-A05E-4E2A-806E-8622F4E2B597--
