Mobile Looking Glass?
by St. Onge,Adam 06 Oct '10

Anyone know of an iPhone application for checking public Looking Glass servers? Boss called me in a panic when I was out for lunch to check on something and would make my life much easier but searching for stuff on iTunes is awful. ============================================================================== This communication, including attachments, is confidential, may be subject to legal privileges, and is intended for the sole use of the addressee.

Thanks to everyone for a wonderful conference--this wraps the last of NANOG50--see you all in Miami! Notes from this morning's session are posted at http://kestrel3.netflight.com/2010.10.06-NANOG50-morning-notes.txt sorry about the gaps, I kinda nodded off now and then--only got 2 hours of sleep last night. ^_^;; Apologies for typos, misspellings, etc. Thanks again for a wonderful conference!! :) Matt

ILNP and DNS (from 2010.10.04 NANOG50 day 1 morning notes)
by Michael Sinatra 05 Oct '10

05 Oct '10

> Michael Sinatra, UCB; what are thoughts around best practices for > auth DNS server in ILNP world, and how do you handle updates for > locator values to the auth servers when a link changes? > A: you need > DNSsec to be running, you make updates, you check authenticity of the > update, etc. How will other networks know about the changes. The initial answer to my question didn't quite get the point of the question, so I followed up. I think ILNP is very interesting because it attempts to create a true I/L split via naming semantics. However, it relies on DNS to do this. Somewhere, there has to be an authoritative DNS server(s) that have the prefix list and preferences for the site. (In ILNP, each host can have its own list of preferred prefixes in the form of L64 records, or they can defer to a site-wide L64 RRset with the LP record.) I acknowledge that this requires a secure dynamic update mechanism (presumably with the border routers doing the updates), and it requires very low ttls to improve convergence. Where this becomes interesting from an operational perspective is when I think about how to address authoritative DNS servers in an ILNP world. The DNS server itself has to be reachable, and the prefix list for the DNS server must be updated when the network topology changes. Hence the question: How should I provision authoritative DNS servers, given that the prefix information is provided via DNS--including the prefix information for the DNS servers themselves--leading to a chicken-and-egg problem. In addition, I would assume that I need something similar to glue records (instead of A or AAAA glue, I need L64 or LP glue). I think one answer would be to have all of my authoritative servers in someone else's network, where they could maintain all of the L64 records completely independent of my DNS infrastructure. With the DNS servers in my network, I don't think there's an answer to the chicken-and-egg problem. Of course, if one of their upstreams dies, my DNS may suffer if I can't withdraw my partner's network's prefixes from the L64 record for my DNS server. This blends into Danny's comment about routing relying on DNS and DNS relying on routing, and to Dave's comment on the binding between the identity and locator being a critical (and difficult) component of the I/L split. I realize that the distinction between operations and protocol development in this discussion may be subject to interpretation, but I also think it's important to understand the operational implications of developing protocols early on. michael

Re: A New TransAtlantic Cable System

Hi All. It appears we're discussing theoretical limits of silica-based glass here. The Press Release assertion talks about what a trader might experience. Hm. I would ask Rob Beck to clarify this point and inform whether the stated objective in the release accounts for the many o-e and e-o conversions on the overland part of the end-to-end trader connection, including the handoffs that occur in the NY and London metros. I know that terrestrially, i.e., here in the US, some brokerage firms and large banks (is there any longer a distinction between those two today?:) have used their clout to secure links that are virtually entirely optical in nature on routes that are under a thousand miles, but this is not an option on a submarine system that's intrinsically populated with electronics, never mind the tail sections that assume multiple service providers getting into the act. Rob? Anyone?

My first thought is that they've found a way to cheat on the 1.5. If you can make it work at 1.4, you get down to 52.2ms - but get it *too* low and all your photons leak out the sides. Hmm.. Unless you have a magic core that runs at 1.1 and a *cladding* that's up around 2.0?

Hey guys, Anyone knows how often does Level3 update their filters? I have a prefix in Europe which has a route-obj from Sunday, it's accepted in Level3 Europe from Monday, but in the US it's still not accepted. Thanks, Florin

IMHO, Nothing beats a good intel NIC. I'm a big fan of the intel pro/1000GT. In terms of performance, I think it is more determined by the card chipset.
