Fiber Automatic Transfer Switch
by Tim Nowaczyk 17 Aug '20

17 Aug '20

I am new to the world of layer-1optical failover solutions. I came across the NTT-AT Intelligent Optical Switch [1] while researching products that can be used to automatically switch a fiber path on link failure. Do any of you have experience with this particular product? Can anyone recommend a similar 1U product that can transfer an optical signal to a secondary path when there’s been a break? Thanks, Tim Nowaczyk [1] https://www.ntt-at.com/product/optical-switch/product.html <https://www.ntt-at.com/product/optical-switch/product.html> -- Timothy Nowaczyk | Senior Network Manager office 703.554.6622 <tel:703.554.6622> | mobile 571.318.9434 <tel:571.318.9434> <http://www.allpointsbroadband.com/>

I created a users group on FB, but uptake has been fairly low. Are there any Zhone-specific mailing lists or communities out there that I'm not yet aware of? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

This is probably a long shot, but are there any AT&T Wireless engineers here, & one who wouldn't mind contacting me off-list? I may be misinterpreting what I'm seeing, but I think you might have a small number of MMSC servers that are down... -- Nathan

Product for heat containment per rack unit?
by David Hubbard 13 Aug '20

13 Aug '20

Curious if anyone has knowledge of a vendor / product designed to make it possible to use back-to-front cooled equipment in racks that need to be ‘sealed’ for heat containment reasons? I’d envision this looking like some kind of adjustable depth sleeve, to get the cold air to the equipment, and perhaps a brush strip opening to allow power cables in? Thanks!

Has virtualization become obsolete in 5G?
by Etienne-Victor Depasquale 13 Aug '20

13 Aug '20

Hi folks, Over the past few weeks, I've attended webinars and watched videos organized by Intel. These activities have centred on 5G and examined applications (like "visual cloud" and "gaming"), as well as segment-oriented aspects (like edge networks, 5G RAN and 5G Core). I am stunned (no hyperbole) by the emphasis on Kubernetes in particular, and cloud-native computing in general. Equally stunning (for me), public telecommunications networks have been portrayed as having a history that moved from integrated software and hardware, to virtualization and now to cloud-native computing. See, for example Alex Quach, here <https://www.telecomtv.com/content/intel-vsummit-5g-ran-5g-core/the-5g-core-…> @10:30). I reason that Intel's implication is that virtualization is becoming obsolete. Would anyone care to let me know his thoughts on this prediction? Cheers all, Etienne -- Ing.

RPKI TAs

so i was trying to ensure i had a current set of TALs and was directed to https://www.ripe.net/manage-ips-and-asns/resource-management/certification/… the supposed TAL at the bottom of the page is pretty creative. anyone know what to do there? i kinda hacked with emacs and get rsync://rpki.ripe.net/ta/ripe-ncc-ta.cerpublic.key.info MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0URYSGqUz2myBsOzeW1jQ6NsxNvlLMyhWknvnl8NiBCs/T/S2XuNKQNZ+wBZxIgPPV2pFBFeQAvoH/WK83HwA26V2siwm/MY2nKZ+Olw+wlpzlZ1p3Ipj2eNcKrmit8BwBC8xImzuCGaV0jkRB0GZ0hoH6Ml03umLprRsn6v0xOP0+l6Qc1ZHMFVFb385IQ7FQQTcVIxrdeMsoyJq9eMkE6DoclHhF/NlSllXubASQ9KUWqJ0+Ot3QCXr4LXECMfkpkVR2TZT+v5v658bHVs6ZxRD1b6Uk1uQKAyHUbn/tXvP8lrjAibGzVsXDT2L0x4Edx+QdixPgOji3gBMyL2VwIDAQAB but kinda expected an rrdp uri too and, to add insult to injury, the APNIC web page with their TAL https://www.apnic.net/community/security/resource-certification/ requires javascript! not to mention the ARIN stupidity as if we needed another exercise in bureaucrats making operations painful. most operations of any size have internal departments perfectly capable of doing that. randy

cloudflare 1.1.1.2 filtered DNS
by William Herrin 11 Aug '20

11 Aug '20

Howdy, Is there an RBL lookup that provides information on why Cloudflare has elected to block a name lookup via the "1.1.1.1 for Families" service or is it a black box where you can only complain via https://report.teams.cloudflare.com/ and maybe they'll do something about it? Thanks, Bill Herrin -- William Herrin bill(a)herrin.us https://bill.herrin.us/
