Toke=E2=80=99s repo has now been updated accordingly. It still = understands the old format as well as the new one. However, it *does = not* read the interim format, because it cannot be distinguished = reliably from the old format, and the two are mutually incompatible. The new stats struct can be extended with new statistics when required. = The old one could be extended with a larger number of classes/tins, but = that proved to be less useful. Although I had left a generous amount of = padding originally, all that space was eventually used up. Also put in now are keywords for the RTT parameter: datacentre =3D 100 us lan =3D 1 ms (covers both ethernet and home wifi) metro =3D 10 ms regional =3D 30 ms internet =3D 100 ms (default) oceanic =3D 300 ms satellite =3D 1 second interplanetary =3D 1 hour - Jonathan Morton
