SFP vs. SFP+
by Jason Lixfeld 18 Feb '11

18 Feb '11

I was asked today what the difference between SFP and SFP+ is. I did really know, so I looked it up and it seems that the SFP spec provides capabilities for data rates up to 4.25Gb/s, whereas SFP+ supports up to 10Gb/s. Naturally, this made me wonder whether or not an optic that supported 10GbE always conformed to the SFP+ standard inherently, or if there are cases where a 10GbE optic might only support the SFP standard, thus having a 4.25Gb/s bottleneck.

Fwd: [arin-announce] IN-ADDR.ARPA Zone Transfer Complete
by John Curran 17 Feb '11

17 Feb '11

Apologies for cross-posting, but I believe this relevant to the NANOG operator community. FYI, /John Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Date: February 16, 2011 3:53:38 PM EST To: <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> Subject: [arin-announce] IN-ADDR.ARPA Zone Transfer Complete Today ARIN and ICANN are jointly working on the transition of the technical management function for the IN-ADDR.ARPA zone from ARIN to ICANN. ARIN carried out the DNS zone maintenance function for IN-ADDR.ARPA since 1997 and worked closed with ICANN throughout the transition period. Immediately upon transfer to ICANN, the IN-ADDR.ARPA zone will also be signed using DNS Security Extensions (DNSSEC), providing end-users with the ability to validate answers to reverse DNS queries. The IN-ADDR.ARPA zone is also in the process of being moved from twelve root servers to dedicated nameservers operated by the five Regional Internet Registries (RIRs) and one operated by ICANN. For more details on the history of this transition please see <http://in-addr-transition.icann.org/>. Regards, Communications and Member Services American Registry for Internet Numbers (ARIN)

AT&T MPLS / BIB Routers
by Mikeal Clark 17 Feb '11

17 Feb '11

We just put in a AT&T MPLS and are having a pretty negative experience with the "Business in a Box" routers they are using for our smaller sites. We are seeing extremely high latency under load. Anyone have any experience with these devices that could shed some light on this? Are they really this bad?

Solar flare to reach earth
by andrew.wallace 17 Feb '11

17 Feb '11

These "coronal mass ejections" will slam into the Earth's magnetic shield. The biggest flares can disrupt technology, including power grids, communications systems and satellites. "Our current view is that the effect of the solar flare is likely to reach Earth later today (Thursday GMT), possibly tomorrow morning," said Alan Thomson, head of geomagnetism at the British Geological Survey (BGS). http://www.bbc.co.uk/news/science-environment-12493980 Andrew

To the people who answer tech questions on this list
by Michael Dillon 17 Feb '11

17 Feb '11

This list serves a number of purposes and one of them is to answer technical networking questions. But this list is also not the only place that these types of questions are asked. For instance, LinkedIn has a Q&A feature where people can ask and answer questions on a wide range of topics. Just today I came across this BGP question: http://www.linkedin.com/answers/technology/information-technology/computer-… I would never suggest that LinkedIn could replace the NANOG mailing list, but it is an interesting complement to it. There is a NANOG group here: http://www.linkedin.com/groups?mostPopular=&gid=40718 and a number of people are using LinkedIn for professional purposes. I know many of you tried out Orkut and then migrated to Multiply.com and found them lacking. But I would suggest that LinkedIn might be more useful, in particular, to provide an entry level tier for questions. A lot of NANOG members are rather intimidated to ask questions which might seem too beginner and I think that the NANOG group on LinkedIn might be a good place to encourage such questions in order to draw out more discussion among NANOG members without boosting the mailing list traffic. What do you think? (Probably best to answer this on the NANOG group over at... --Michael Dillon http://www.linkedin.com/profile/view?id=13566587
