I'm just curious - what is the largest OSPF core (in terms of number of routers) out there?

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

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.

He mentioned doing work (for hire) in AU and such. I think he may be in for a rude awakening since our past experience with the Australian authorities is they are more active chasing ddos/cyber-crimes than the U.S. Those guys pull out all the stops to prosecute. (Which I am happy to see) Sadly, here in the U.S. you have little to no chance of getting assistance unless the client is a bank or very public company. In fact, that doesn't always work. (Even with direct FBI contacts in multiple field offices) Kind of a shame.. We are likely already tracking his botnets so I almost welcome it as well. Out of curiosity, I did pull some stats over the last 60 days and we have seen more attacks originating from the India area than we have seen in the past 12 months. Maybe it's a coincidence. I would almost bet this guy has never carried out an attack in his life and simply trying to gain some publicity. *shrug* ------Original Message------ From: Jeffrey Lyon To: Beavis Cc: nanog(a)nanog.org Subject: Re: Copyright Enforcement DoS/DDoS Attacks Sent: Sep 9, 2010 11:43 AM He may get some business out of it, now that he has effectively put out a DDoS for hire ad.

Anyone notice any issues with Cogent? Internet Health Report showing some high latency to Verizon and a couple of other carriers.

DS3 mux recommendation
by Jay Nakamura 09 Sep '10

09 Sep '10

I haven't researched stand alone DS3 mux in a long time and was wondering if anyone can recommend a DS3 Mux. I have used Adtran before. (Long ago) The products back then worked fine on line level but management interface was awful and if you threw too much SNMP at it and the management interface locked up. Are there anything better out there these days? TIA, -Jay

Anyone seeing problems with PCCW?
by Jared Geiger 09 Sep '10

09 Sep '10

I'm seeing routes die on PCCW's network both in Amsterdam and Washington DC with destinations to Asia (Hong Kong is mainly what I've tested). However the routes are fine from Los Angeles. Does anyone know of any fiber cuts or issues that would be causing this?
