100GbE beyond 40km
by Randy Carpenter 29 Sep '21

29 Sep '21

How is everyone accomplishing 100GbE at farther than 40km distances? Juniper is saying it can't be done with anything they offer, except for a single CFP-based line card that is EOL. There are QSFP "ZR" modules from third parties, but I am hesitant to try those without there being an equivalent official part. The application is an ISP upgrading from Nx10G, where one of their fiber paths is ~35km and the other is ~60km. thanks, -Randy

Robocall Mitigation Database Call Blocking Deadline Is Today
by Sean Donelan 28 Sep '21

28 Sep '21

According to the FCC, 4,798 companies had filed in the Robocall Mitigation Database with many hundreds of carriers, including all of the largest phone carriers, certifying to implementation of STIR/SHAKEN standards on their IP networks. Beginning today, if a voice service provider’s certification and other required information does not appear in the FCC’s Robocall Mitigation Database, intermediate providers and voice service providers will be prohibited from directly accepting that provider’s traffic. Note the word "directly." Guess what's going to happen? https://www.fcc.gov/document/fcc-robocall-mitigation-database-call-blocking…

VoIP Provider DDoSes
by Mike Hammett 28 Sep '21

28 Sep '21

As many may know, a particular VoIP supplier is suffering a DDoS. https://twitter.com/voipms Are your garden variety DDoS mitigation platforms or services equipped to handle DDoSes of VoIP services? What nuances does one have to be cognizant of? A WAF doesn't mean much to SIP, IAX2, RTP, etc. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Rack rails on network equipment
by Andrey Khomyakov 28 Sep '21

28 Sep '21

Hi folks, Happy Friday! Would you, please, share your thoughts on the following matter? Back some 5 years ago we pulled the trigger and started phasing out Cisco and Juniper switching products out of our data centers (reasons for that are not quite relevant to the topic). We selected Dell switches in part due to Dell using "quick rails'' (sometimes known as speed rails or toolless rails). This is where both the switch side rail and the rack side rail just snap in, thus not requiring a screwdriver and hands of the size no bigger than a hamster paw to hold those stupid proprietary screws (lookin at your, cisco) to attach those rails. We went from taking 16hrs to build a row of compute (from just network equipment racking pov) to maybe 1hr... (we estimated that on average it took us 30 min to rack a switch from cut open the box with Juniper switches to 5 min with Dell switches) Interesting tidbit is that we actually used to manufacture custom rails for our Juniper EX4500 switches so the switch can be actually inserted from the back of the rack (you know, where most of your server ports are...) and not be blocked by the zero-U PDUs and all the cabling in the rack. Stock rails didn't work at all for us unless we used wider racks, which then, in turn, reduced floor capacity. As far as I know, Dell is the only switch vendor doing toolless rails so it's a bit of a hardware lock-in from that point of view. *So ultimately my question to you all is how much do you care about the speed of racking and unracking equipment and do you tell your suppliers that you care? How much does the time it takes to install or replace a switch impact you?* I was having a conversation with a vendor and was pushing hard on the fact that their switches will end up being actually costlier for me long term just because my switch replacement time quadruples at least, thus requiring me to staff more remote hands. Am I overthinking this and artificially limiting myself by excluding vendors who don't ship with toolless rails (which is all of them now except Dell)? Thanks for your time in advance! --Andrey
