Re: rpki vs. secure dns?

Another difference between RPKI and ROVER which hasn't come up much: RPKI incorporates a lot of pre-existing machinery from X.509 et al. This drags in some tedious detail which makes people's eyes cross, but it gives us some tools which simply aren't available in DNS at present. In particular, X.

Tim Yes we have built several links with the 1310nm devices on Corning LEAF. One span distance was 14 KM. Can we offer you a quote on optics and installation support? Thanks, Kevin L. Karch Network Specialist Direct: 847-833-8810 Fax: 847-985-5550 Email: kevinka...@vackinc.com Web: www.vackin

1310nm optics over Corning LEAF G.655?

Anyone run 1000BASE-LX/10GBASE-LR 1310nm optics over a ~10km Corning LEAF G.655 span? I understand this fiber is not optimized for such usage, but what is the real-world behaviour? I'm having a hard time finding hard data. (Normal optics will be 1550nm and DWDM over ~40-100km spans.) -- Tim:>

Number of providers

Based on feedback we have received at http://as-rank.caida.org/ we are in the process of updating our AS relationship inference algorithm. We're interested to know how many providers different ASes have based on their size. We assume that it changes with size of the AS, e.g. Tier-1 have zero.

Re: Comcast IPv6 Update

My understanding is that Comcast only does IPv6 on business customers that are on their "backbone" network, not those on their docsis network. If you have BGP or fiber with 7922 you should be able to get IPv6. - Jared On Jun 1, 2012, at 9:51 AM, Jimmy Sadri wrote: > Wow... I just wanted some i
