[NANOG] RackMount DC to AC Inverters
by Gregory Boehnlein 17 May '08

17 May '08

Hello all, I have some equipment going into a Telco Co which only offers battery backup on it's DC power plant. Most of the equipment that is already moving into that facility is AC powered, so I am looking for advice on rackmount DC inverters. Looking for something that can accommodate inverting enough power to load a 30 AMP 110 circuit, preferably something that has N+1 redundancy.. I'm not finding a lot of options on Google, so I figured that I would ask here...

[NANOG] peering between ASes
by Kai Chen 17 May '08

17 May '08

Hi, here is a quick question. 1. Beside public peering in IXP and private peering between two dedicated ASes, are there any other interconnection models in the current Internet? 2. How does private peering implement, just a router from each AS and a link inbetween? Do they have multi-access in one peering location? I mean one router from an AS peer with two/more routers from another AS? Cheers,

This _is_ Microsoft we're talking about, remember. 'sense' and 'Microsoft' are, at a =minimum= orthogonal to each other -- and may not even inhabit the same address-space. <wry grin> As for standards, it is official Microsoft policy to "embrace and extend", not to implement in a way compatible with the rest of the world. *sigh* I -don't- believe the rumor that "PMTUD/Vista Ultimate" sends incrementally increasing-size packets, and uses the first one that -doesn't- get through as the size limit. <giggle>

#include <sys/nanog/page.h> An AIM security engineer/admin is requested. Please contact off-list. (*) I'll settle for an AOL security type with a buddy who works in AIM. It's all good at this point.

[NANOG] Hibernia Atlantic Outage
by Paul Wall 16 May '08

16 May '08

I'm hearing reports of a Hibernia outage on one of their fiber paths, with downtime approaching a week. Does anybody know what's going on there, and when they expect to have service restored? Which provider(s) are impacted? Was their diverse path impacted as well (as with prior Hibernia outages), or just this path? Paul

Re: [NANOG] US DoD receives chunked IPv6 /13 (14x /22 but not totallyconsecutive)
by Deepak Jain 16 May '08

:_) Another concept that might be useful with *that* much address space is the concept of modeling your ENEMIES' networks inside of unique space (persistently, forever). I'm sure we aren't far from the days where boxen will be set up to emulate the interaction between hundreds of other nodes, latency, jitter and packet loss included. It might be a fun project to be asked to pursue. There really isn't a platform in current address space to do that (once you add persistently and multiple enemies) to the equation. :) Deepak Dorn Hetzel wrote: > Brings a whole new meaning to packet fragmentation :) > > On Fri, May 16, 2008 at 5:05 PM, Deepak Jain <deepak(a)ai.net > <mailto:deepak@ai.net>> wrote: > > > > Perhaps next each round of ammo will have its own IPv6 address. > > > > Perhaps every round will (or anti-personnel) mine will be stamped with > its V6 address so you can track its shrapnel for all time?

Deepak, Excellent question. I'm currently deploying a test environment for a large scale wifi network. You can see more project info at wiki.socalwifi.org and at socalwifi.blogspot.com. I am documenting everything we are doing and will have a Blog post up soon regarding our kerberos/radius/VPN deployment and how we load test/scale it. i have yet to see any existing information on the back end components specifically related to muni wifi. I would imagine standard documentation/white papers related to scaling a large enterprise wifi network apply.

[NANOG] Fixed Orbit

Anyone have any contacts at Fixed Orbit or know anything about their setup? We have one peer that doesn't show in Fixed Orbit's tables. The peer has been online for 5 months so I doubt that the lack of reflection is due to staleness. I've emailed Fixed Orbit but received no response. -- Morgan A.
