- this month, another knee was at 150k [Dec 4th] and similarly garbled results came out. Again, no response. ...in this one year we've seen the shape of the climb return to the curve characterized by two years 99-01. Going for e? I'm not quite sure what the current point of the report is if no-one responds to even it breaking.
Knee? Shape? Curve? Are you reading the same CIDR report that I see here every Friday? The report that I see is basically a dump of raw data. Perhaps the author needs to remember the distinction between data and information and make the CIDR report into something that people *WANT* to read. This posting of yours contained far more information than any CIDR report.
Those believing otherwise are encouraged to send real, hard data. There is no meaningful data I can find since the Bellovin/Bush/ Griffin/Rexford 2001 paper.
I don't know why people like to post cryptic references to documents or meetings etc. Perhaps there is an implicit desire to hide it from outsiders who are not part of the secret inner circle? Perhaps this type of behavior is at the root of the growing problems, i.e. clue is not being spread around because people are too cliquish in the way that they present this info. I'm not talking about NANOG meetings here, just the list, which arguably reaches more people than the meetings. Now, on to Bellovin et al. Janet Rexford wrote this paper on filtering http://www.research.att.com/~jrex/papers/filter.pdf This was presented at NANOG but the NANOG site here http://www.nanog.org/mtg-0105/prefix.html points to Janet's site here http://www.research.att.com/~jrex/nanog/lost.html (note the word LOST in the URL) which points to Randy's slides here http://psg.com/~randy/010521.nanog/ unfortunately those appear to be lost... But there is some video from IETF 51 here http://videolab.uoregon.edu/events/ietf/ietf51.html which might be the same stuff. Bush talks on Routing Issues. One would think that if the problems noted in 2001 are not being solved, then perhaps a review of this material might prove more fruitful than more studies of the data. According to the plot here http://www.cidr-report.org/ the average announcements per origin AS has actually taken a turn for the better. And the chart of the BGP table here http://bgp.potaroo.net/ seems more like a power curve than the exponential curve prior to 2001. --Michael Dillon --Michael Dillon
