Re: IPv6? Why, you are the first one to ask for it!

(I asked if they had plans for a friendly user test I could join.) He also said that they understand that IPv6 is not ready because OS vendors have not implemented IPsec. Talk about a bozo filter...

Re: wanted: your old NAT home router
Hi, FYI, a first report with test results for 34 devices is available athttp://fit.nokia.com/lars/tmp/2010-hgw-study.pdf. Slides that summarize the results are at http://fit.nokia.com/lars/tmp/2010-hgw-study-slides.pdf. We have received another 30-odd devices as donations, which we'll add to the testbed and include in a follow-up study. If you have an unused, spare home gateway to donate to this effort, please contact us at nat-st...@fit.nokia.com. We're also interested in obtaining a DSLAM and a CMTS.

If you have an old clunker lying around somewhere, please contact me off-list. I'll cover shipping via DHL. Feel free to forward this email as you see fit. The boxes will find a permanent home at the University of Helsinki. Study results will be published openly. The intent is that this collection become a resource for the community to be shared for future studies. Caveat: The boxes should NAT between Ethernet interfaces - we don't have DSL or cable access equipment in the lab setup at the moment.

I've also been pointed at mini-DSLAMs that are reasonably cheap. (We're planning to have a first draft study ready mid-May, and for that, the best we can do is add more Ethernet-Ethernet NATs to the testbed.)

TCP should be slightly more intelligent and start considering rtt jitter as its primary source of congestion information. TCP Vegas did this but sadly it never became popular. (It doesn't compete well with Reno.) FWIW, Compound TCP does this (shipping with Vista, but disabled by default.) There are other delay-based or delay-sensitive TCP flavors, too.

I would love to be able to configure my router/cable modem/dsl box with queue-size 50ms and have it compute, for the current link speed, 50ms of buffer. if the vendors got active and deployed better queueing schemes, that'd be great. In the meantime, we've also started some work that will allow bulk transfer applications to transmit in a way that is designed to minimize queue lengths: http://www.ietf.org/html.charters/ledbat-charter.html Lars smime.p7s Description: S/MIME cryptographic signature
