A year ago we built NREN backbone using TRILL instead of MPLS. 40 POPs, no central controller, RFC standardized TRILL protocol i.e. L2 routing using IS-IS, no STP. See my recent presentation at http://md.bts.sk/sanet-100g-2.pdf for more details. Much easier to setup, operate & maintain than MPLS and obviously much lower cost. Based on 6-months production experience, my recommendation would be to stay away from MPLS in the campus. With kind regards, M.

Well their addresses are now known so one way would be for each ISP to drop traffic from them. If people don't fix them why should these devices stay on the net? If say Comcast has a million of them it might be tricky to scale but not impossible It'd take a bit of effort and care to aggregate and disseminate the data to each responsible AS, there'd be risk of bad guys getting the data and false positives/people spoofing to attack others. They'd also be building a tool that some might try to hijack for other purposes. None of that is an excuse to do nothing as is usually the result with any suggested measure that involves doing work to fix a problem I know ISPs generaly don't want the support calls but they'll end up with them and a legislative burden with commerial liability if they don't sort it out themselves. brandon

But the problem is that this trashes caching, and DNS does not work without caches. At least not if you want it to survive when the going gets tough. If we're going to solve this we need to innovate beyond the pathetic CNAME chains that todays managed DNS services make us use, and get truly distributed load-balancing decision-making (which only will work if you give it sensible data; a single CNAME is not sensible data) all the way out in the client application. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE +46 705 989668 Well, I'm INVISIBLE AGAIN ...

Re: Dyn DDoS this AM?
by Alexander Maassen 21 Oct '16

21 Oct '16

Feel free to feed me with attack sources. Once those companies notice their precious mail does not arrive at clients. They will attempt to fix things. Sad but true. Kind regards, Alexander Maassen - Technical Maintenance Engineer Parkstad Support BV- Maintainer DroneBL- Peplink Certified Engineer -------- Oorspronkelijk bericht --------Van: "Patrick W. Gilmore" <patrick(a)ianai.net> Datum: 21-10-16 17:48 (GMT+01:00) Aan: NANOG list <nanog(a)nanog.org> Onderwerp: Re: Dyn DDoS this AM? I cannot give additional info other than what’s been on “public media”. However, I would very much like to say that this is a horrific trend on the Internet. The idea that someone can mention a DDoS then get DDoS’ed Can Not Stand. See Krebs’ on the Democratization of Censorship. See lots of other things. To Dyn and everyone else being attacked: The community is behind you. There are problems, but if we stick together, we can beat these miscreants. To the miscreants: You will not succeed. Search "churchill on the beaches”. It’s a bit melodramatic, but it’s how I feel at this moment. To the rest of the community: If you can help, please do. I know a lot of you are thinking “what can I do?" There is a lot you can do. BCP38 & BCP84 instantly come to mind. Sure, that doesn’t help Mirai, but it still helps. There are many other things you can do as well. But a lot of it is just willingness to help. When someone asks you to help trace an attack, do not let the request sit for a while. Damage is being done. Help your neighbor. When someone’s house is burning, your current project, your lunch break, whatever else you are doing is almost certainly less important. If we stick together and help each other, we can - we WILL - win this war. If we are apathetic, we have already lost. OK, enough motivational speaking for today. But take this to heart. Our biggest problem is people thinking they cannot or do not want to help. -- TTFN, patrick > On Oct 21, 2016, at 10:55 AM, Chris Grundemann <cgrundemann(a)gmail.com> wrote: > > Does anyone have any additional details?

Does anyone make a coherent CWDM 40G QSFP? I thought so, but the first couple places I checked, I struck out at. This would be for a passive mux\MROADM. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Excessive Netflix DNS Traffic?
by Eamon Bauman 19 Oct '16

19 Oct '16

Hi all, Is anyone seeing excessive DNS traffic from game consoles (Xbox One, PS4) running Netflix? Starting 9/29 we have been seeing significant volume of DNS traffic from game consoles on our campus to our caching recursive boxes. Logs show repeated requests for api-global.netflix.com and nrdp.nccp.netflix.com. Anyone else experiencing this? Eamon
