Dark fiber usage info request - know-how pointers and experience sharing
by Stefan 02 Nov '12

02 Nov '12

Looking at dark fiber leasing as an alternative for existing ISP-acquired MPLS, MetroE, P2P, etc. services. I would appreciate some pointers (links) into specific technologies used with dark fiber, as direct consumer (not ISP). I am not looking for the theory behind (C)DWDM, but rather real life implementations and experience with folks operating such. Highly appreciated would also be extra info on what the learning curve required for traditional network engineering crew to operate devices terminating into such, and maybe even work (installation and operation) needed to maintain plants with this infrastructure. TIA, ***Stefan

Network scan tool/appliance horror stories
by Pedersen, Sean 02 Nov '12

02 Nov '12

We're evaluating several tools at the moment, and one vendor wants to dynamically scan our network to pick up hosts - SNMP, port-scans, WMI, the works. I was curious if anyone had any particularly gruesome horror stories of scanning tools run amok.

Does anyone know if there is an updated version of this book? Year 2000 seems so distant now... http://www.amazon.com/dp/B0051TM4RC/ref=rdr_kindle_ext_tmb --Andrey

Anyone else suddenly getting shaped/throttled by comcast this morning?
by Ray Wong 01 Nov '12

01 Nov '12

Looks to have started at almost exactly 8am Eastern, though in our case it's mostly west coast traffic(dst to comcast retail customers), so seems unlikely to be aftermath of storm damage, unless someone didn't look very closely at their traffic before noodling things. Still, coming up on 3 hours my outbound hasn't topped exactly a gbit, which seems a little convenient... -R>

IETF Nominations Committee seeks operations community input
by Matthew Lepinski 31 Oct '12

31 Oct '12

The IETF Nominations Committee (NomCom) is currently working to select a new Operations Area Director who will replace Ron Bonica (who is stepping down next March). Ideally, the Operations area within the IETF serves as a focal point for communication and collaboration with the network operations community. I understand that over the years the Operations area has had varying degrees of success at fostering productive discussion with the networks operations community. The IETF NomCom would greatly appreciate input from network operators to ensure that we select an Operations Area Director who best serves the needs of the community. The NomCom welcomes general feedback on issues that the NomCom should take into account in selecting an Operations Area Director, including things that the IETF Operations area could/should be doing to better interface with the network operations community. Please do not hesitate to send input/feedback by email to the NomCom at nomcom12(a)ietf.org Additionally, the specific individuals that the NomCom is currently considering for the position of Operations Area Director are: -- Linda Dunbar -- Joel Jaeggli -- Melinda Shore -- Tina Tsou The NomCom welcomes any feedback specifically related to any of these individuals, and whether they are particularly well suited for the position of Operations Area Director. The IETF NomCom takes very seriously the confidentiality of any input provided to the committee (as per RFC 3777). Thank you for any help that you can provide to the IETF NomCom, - Matt Lepinski nomcom-chair(a)ietf.org

Google burp
by Blair Trosper 31 Oct '12

31 Oct '12

I guess I'll be the one to ask...what's going on over at Google? Service interruptions and front-end errors all over the place across what appears to be all services, though Gmail seems to have bounced back up. Google's service disruption is about to bring Twitter's service to its knees as people complain and try to figure out what's going on. Blair Trosper Updraft Networks & The North Texas GigaPOP
