On a related note, I have been poking around in ns2 trying to see if I can simulate TCP flows over a UFB service to see the effect of different BWP burst sizes.

I don't get the latter two acronyms.

UFB == Ultra Fast Broadband, the marketing term for (basically) fibre to the home/premises in New Zealand (see, eg, http://ufb.org.nz/). BWP I'd assume was BandWidth Product from context. Crossing the streams from another Dave Taht reply to the NZNOG list:

Lastly, I couldn't help but want this big islam firmware upgrade for ipv6 support to include bufferbloat related fixes, but I know I'm dreaming....

Let's dream big. It sounds like Chorus (who run a large chunk of the DSL headends in New Zealand) are already talking to their vendor at present about wanting a firmware release with a specific combination of features. And contemplating a country-wide rollout when they find one they can put into production. That's definitely not going to be an upgrade that happens every day! (Nor is it likely to be happening tomorrow, so there's still time to tweak the plan.) If there are specific ISAM features/versions/bug fixes/whatever that would make the bufferbloat situation better, it'd be worth talking to some of the Chorus folks (two of whom I see active on the NZNOG list this week, and some of whom I assume will be at the NZNOG conference later this week) and giving them specific things to add to their "and we want these features too" list. Because if it's not this country-wide rollout, it might be Many Months before there's another one to try to get it included in. Ewen
