ECN
by Mikael Abrahamsson 08 Nov '08

08 Nov '08

Hi, On LKML (Linux Kernel Mailing List) there is talk <http://lkml.org/lkml/2008/11/4/151> about shipping the Linux kernel with ECN turned on by default (it was on by default a few years back but that change was reverted due to too many sites dropping ECN enabled SYNs). Recent investigations <http://www.imperialviolet.org/binary/ecntest.pdf> shows that 0.5% of end hosts will drop SYN packets with ECN turned on. This is approximately the same rate I have seen for A/AAAA adoption in this tread <http://www.ops.ietf.org/lists/v6ops/v6ops.2008/msg01585.html>. Do we in the operational ISP community have an opinion on ECN adoption that we want to voice? As far as I can discern from <http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ftwrdecn.html> for ECN to actually be useful, we (the ISPs) have to turn this option on in the routers as well. Is anyone doing this today? What vendors support it? When I thought about it, the IP core (10G links etc) first came to mind, and there it's fairly easy to roll out (since I guess a lot of us do WRED already), but what about on slower links? Would it make sense to have our DSLAMs do this? What about DSL/cable modems (well, vendors should first realise that FIFO is not great to begin with :P) ? <http://www.icir.org/tbit/> is a summary page I found on ECN that looks like a good resource for further reading. Is anyone looking into including ECN configuration into some BCP document? -- Mikael Abrahamsson email: swmike(a)swm.pp.se

Google SMTP acceptance policy?
by Jonathan Traylor 06 Nov '08

06 Nov '08

Anyone have guidance on how to legimately stay out of Google/GMail's spam classifier and arrive at the inbox? We have a domain that is relatively newly registered, has proper MTA configuration and SPF records that I haven't been able to find on any blocklist, but GMail sends email from it straight to the spam folder. I haven't been able to find useful documentation for GMail in this regard around the web. Have looked at abuse.net's info, links and resources. Thanks, -- Jonathan

Sprint v. Cogent, some clarity & facts
by Patrick W. Gilmore 06 Nov '08

06 Nov '08

Having skimmed the Sprint / Cogent threads, I saw multiple errors and lots of really bad guesses. Instead of replying individually, I thought I would sum up a few facts so everyone was on the same page. This way when we run off into another 100 post thread, we can at least -start- from reality (although I would bet serious cash on long odds we will diverge from it soon enough). 1. Neither Sprint nor Cogent have transit Both Sprint & Cogent are transit-free networks. (Notice how I carefully avoided saying "tier one"?) Whether one or both _should_ have transit is not a fact, and therefore outside the scope of this e- mail, but that neither have transit today is a fact. (And please don't tell me how Network X has 100 Mbps of transit in Sri Lanka because they are too lazy to lease undersea cable. If you don't understand what I am saying here, stop reading now.) 2. The Internet cannot "route around" de-peering I know everyone believes "the Internet routes around failures". While occasionally true, it does not hold in this case. To "route around" the "failure" would require transit. See item #1. 3. Standard transit contracts do not guarantee full connectivity If you are a Cogent customer, it is very unlikely your contract will allow you SLA or other credits for not being able to reach Sprint unless you negotiated something special. I doubt Sprint's standard contract is much different. Transit contract SLAs end at AS boundaries. This is because Network A has no control over Network B and therefore will not give credit if Network B fails. Of course, you can still sue, threaten to terminate, etc., but the letter of the contract almost certainly says nothing about packets going beyond your transit provider's ASN. 4. There is a reason behind ratios which has nothing to do with telco "sender-pays" Hot potato routing + very poor ratios puts much more of the cost on the receiving network. This is a valid, logical, and costly concern for receiving networks. The concern can be alleviated by cold-potato routing through accepting MEDs, anycast, CDN, and other technologies; to which the receiving network may say they cannot send proper MEDs, etc. Whether the problem can or should be worked through is not a fact, though. That this issue has nothing to do with telco "sender- pays" mentality is. (Of course, the telcos might still have that mentality, but that doesn't change the facts.) 5. Cogent has been disconnected several times Cogent has been de-peered (e.g. Teleglobe, L3, Sprint) and/or performed de-peering themselves (e.g. Telia) multiple times. Cogent has been disconnected from another network more times & for longer (in each instance?) than every other transit free network combined for the last decade. (In fact, if memory serves, for the history of the Internet - but I'm not quite sure enough to guarantee it as fact.) Cogent has also de-peered many non-transit-free networks, at least sometimes without even notifying the peer prior to disconnection. Whether that makes Cogent the bully-er or the bully-ee is not fact, so I will not comment on that here. There are probably other errors I missed while skimming the longer posts. But this should get us started on a good, clean, factual footing for future flights of fancy. -- TTFN, patrick
