No you're not, it would be considerably more expensive if you were paying for what you think you're buying. You're being sold something less, the small print usually tells you.

Re: "ARPANet Co-Founder Predicts An Internet Crisis" (slashdot)

Isn't this same Dr. Larry Roberts who 5 years ago was claiming, "based on data from the 19 largest ISPs," or something like that, that Internet traffic was growing 4x each year, and so the world should rush to order his latest toys (from Caspian Networks, at that time)? http://www.dtc.umn.edu/~odlyzko/doc/roberts.caspian.txt All the evidence points to the growth rate at that time being around 2x per year. And now Larry Roberts claims that current Internet traffic is around 2x per year, while there is quite a bit of evidence that the correct figure is closer to 1.5x per year, http://www.dtc.umn.edu/mints Andrew Odlyzko > On Thu Oct 25, Alex Pilosov wrote: On Thu, 25 Oct 2007, Paul Vixie wrote: > > "Dr. Larry Roberts, co-founder of the ARPANET and inventor of packet > switching, predicts the Internet is headed for a major crisis in an > article published on the Internet Evolution web site today.

We all remember how that went (wasn't there NANOG tshirt with Bob eating his hat?) b) In the words of Randy Bush, "We tried this 10 years ago, and it didn't work then". Everyone was doing flow-based routing back in '90-95 (cat6k sup1, gsr e0, first riverstoned devices, foundry ironcore, etc). Then, everyone figured out that it does not scale (tm Vijay Gill) and went to tcam-based architectures (for hardware platforms) or cef-like based architectures for software platforms. In either case, performance doesn't depend on flows/second, but only packets/second. Huge problem with flow-based routing is susceptibility to ddos (or abnormal traffic patterns). It doesn't matter that your device can route 1mpps of "normal" traffic if it croaks under 10kpps of ddos (or codered/nimda/etc). -alex [not mlc anything] [mlc]

Hotmail/MSN postmaster contacts?
by Weier, Paul 26 Oct '07

26 Oct '07

Any Hotmail/MSN/Live postmasters around? My company sends subscription-based news emails -- which go to thousands of users within Hotmail/MSN/Live. I appear to be getting blocked recently after years of success. I have read the postmaster doco at MSN. I have put SPFs for SenderID into many of my news station domains but it doesn't seem to be affecting my success at delivery over other domains which do not yet have any such configs. What am I missing to get un"blacklisted"? I can't seem to find any human contact info on there. Any offline contact would be greatly appreciated.

RE: BitTorrent swarms have a deadly bite on broadband nets
by odlyzko＠dtc.umn.edu 26 Oct '07

Flat rate schemes have been spreading over the kicking and screaming bodies of telecom executives (bodies that are very much alive because of all the feasting on the profits produced by flat rates). It is truly amazing how telecom has consistently fought flat rates for over a century (a couple of centuries, actually, if you include snail mail as a telecom technology), and has refused to think rationally about the phenomenon. There actually are serious arguments in favor of flat rates even in the conventional economic framework (since they are a form of bundling). But in addition, they have several big behavioral economics effect in stimulating usage and in eliciting extra spending. This is all covered, with plenty of amusing historical examples, in my paper "Internet pricing and the history of communications," Computer Networks 36 (2001), pp. 493-517, available at http://www.dtc.umn.edu/~odlyzko/doc/history.communications1b.pdf Now flat rates are not the answer to all problems, and in particular are not as appropriate if marginal costs of providing service are high, or else if you are trying to limit usage for whatever reason (whether to fend off RIAA and MPAA, or to limit pollution in cases of car transportation). But they are not just an artifact of an irrational consumer preference, as the conventional telecom economics literature and conventional telco thinking assert.

OT - spam from Choice Resale
by Chris Woodfield 24 Oct '07

24 Oct '07

Hello, I'm guessing that you've scraped my email address from one or more professional mailing lists (NANOG, cisco-nap, et al). Being in this business, you should probably know that unsolicited marketing emails such as these, even when targeted, are *highly* frowned upon and do very little to enhance your company's reputation. Most call it "spam". More to the point, they annoy the hell out of me personally. Please be assured that thanks to this spam, Choice Resale will never be considered as a candidate for my network resale needs. NANOG, cisco-nsp: any of you get this too?
