SNMP Monitoring of a Transfer Switch relay
by Tom Beecher 14 May '10

14 May '10

I'm presently doing some research into a SNMP-enabled device to monitor a set of aux contacts on our transfer switch in order to be able to monitor it's status (on generator or on commercial) from our monitoring platform. I've seen a few interesting devices out there that can accomplish this, however I thought I'd query the list to see if anyone has thoughts about a particular unit they've worked with. Thanks in advance, Tom

IPv6 eyeballs?
by Vasil Kolev 14 May '10

14 May '10

Hi all, This seems like the proper time to ask, seeing how many people are there asking for IPv6 transit - does anyone have any kind of stats how many eyeballs are there that have IPv6, and are there any of them that have a better service over v6 that over v4 (my guess here is universities or other academical institutions that have really big v6 pipes)? The reason for this question is that s few weeks ago I wrote an initial list of what we (as a medium-sized content provider) need to do to be able to push traffic over v6, and with careful testing and everything it should fit in six months. What's not known is it worth to start implementing it. We pretty much accept as given that no carrier will limit its own users to v6 only in the near (1-2-3 year) future, but with stuff like CGN/LSN degradation could be expected to show up in the v4 service. -- Regards, Vasil Kolev

BGP and convergence time
by Jay Nakamura 14 May '10

14 May '10

So, we have two upstreams, both coming in on Ethernet. One of our switch crashed and rebooted itself. Although we have other paths to egress out the network, because the router's Ethernet interface didn't go down, our router's BGP didn't realize the neighbor was down until default BGP timeout was reached. Our upstream connectivity was out for couple minutes. I am looking for ways to detect neighbor being down faster so traffic can be re-routed faster. I can do BFD internally but the issue is how the upstream is going to detect the outage and stop routing our traffic to that downed link. I have asked both of my upstreams and one said they don't do anything like that, second upstream I am still waiting on the answer. My question is, do other carriers do BFD or any other means to detect the neighbor being down faster than normal BGP will allow? (Both upstreams are major telcos [AT&T and Qwest], so I think they are less flexible than some others.) Or, has anyone succeeded in getting something done with those two carriers? Thanks!

Did anyone hear about this? Describing the National Broadband Network as a $43 billion "white elephant", > he confirmed the Coalition would not go ahead with the program Prime Minster > Kevin Rudd argues will deliver faster internet speeds across the country. > http://www.theaustralian.com.au/in-depth/budget/tony-abbott-would-slash-pub… So, vote for an internet filter or vote for no NBN?

Dark fiber / transport in Virginia
by Courtney, Mike 13 May '10

13 May '10

All, I am interested in finding out about dark fiber / transport resources along I-81 or I-64 in the western part of Virginia. I’d like to find a transport provider that could connect to a “meet me” room in either Roanoke, Charlottesville, Richmond, DC, or even Charleston, WV. I’m trying to price out alternatives to the telco transport and data delivery model and I’m new to the Virginia market. Thanks for any help that you can offer! -Mike
