AT&T Hiccup
by J. Oquendo 10 Sep '10

Alright, since things are mighty quiet on a Friday (either that or everyone on NANOG is now blacklisted somehow and I'm not getting mail), I'd figure to go the PITA route (as usual) and I'd ask a simple question worthy of the mandatory responses of: "on topic questions are not the topic of this list!", "this is not the outage list", "how is this related to networking operations" Did anyone see AT&T flake off the face of the map within the last 30-40 minutes? I know I did! (Seriously I did I did!) Client: "We has no Internet" Me: thinking to myself... "they need to call their provider... Due diligence tracepath/ping/isitdownforeveryoneorjustme time...

Convenience or slippery slope... or something else?

10 Sep '10

A friend brought this to my attention: http://ipq.co/ He saw it at http://news.ycombinator.com/item?id=1678324 I'm not sure whether to shriek in joy or in pain. Will data from this service - if it is a worthy service - propagate properly? Play nicely with or break other people's toys? Is it a gimmick? Reese

Reverse traceroute and spoofing of sources of packets?
by Christopher Morrow 10 Sep '10

10 Sep '10

I missed this meeting/preso when it happened (yes, 5+ meetings ago) <http://www.nanog.org/meetings/nanog45/abstracts.php?pt=MTE4OCZuYW5vZzQ1&nm=…> I note the talks about using spoofed source packets to do some measurement, I didn't see anyone in the video say: "But spoofing is bad, but you want YOU to be able to do this? what? isn't that a little hypocritical?" Isn't it? and why would someone (an isp) disable BCP38 for this sort of activity? -Chris

eBGP Multihop
by Graham Beneke 10 Sep '10

10 Sep '10

I have been asked to investigate moving an entire network to multi-hop on all the eBGP sessions. Basically all upstreams, downstreams and peers will eBGP with a route reflector located in the core. This RR will be some kind of quagga or similar box. The dev guys want to be able to poke at the BGP feeds directly and do *magic* that standard router aren't capable of. My gut feel is that this is a bad idea. Besides anything else it makes sane link state detection very challenging - especially where we have multiple sessions with a peer. Is their any BCP or operational experience that agrees or disagrees with my gut. ;-) -- Graham Beneke

Sustaining the Internet with hyperbolic mapping
by Eugen Leitl 10 Sep '10

10 Sep '10

http://www.nature.com/ncomms/journal/v1/n6/full/ncomms1063.html Sustaining the Internet with hyperbolic mapping Marián Boguñá, Fragkiskos Papadopoulos & Dmitri Krioukov Nature Communications 1 , Article number: 62 doi:10.1038/ncomms1063 Received 06 April 2010 Accepted 06 August 2010 Published 07 September 2010 Abstract The Internet infrastructure is severely stressed. Rapidly growing overheads associated with the primary function of the Internet—routing information packets between any two computers in the world—cause concerns among Internet experts that the existing Internet routing architecture may not sustain even another decade. In this paper, we present a method to map the Internet to a hyperbolic space. Guided by a constructed map, which we release with this paper, Internet routing exhibits scaling properties that are theoretically close to the best possible, thus resolving serious scaling limitations that the Internet faces today. Besides this immediate practical viability, our network mapping method can provide a different perspective on the community structure in complex networks.
