Open Souce Network Operating Systems
by Colton Conor 04 May '18

04 May '18

If one were to deploy whitebox switches, X86 servers, low cost ARM and MIBPS CPE devices, and basically anything that can run linux today, what network operating system would you recommend? The goal would be to have a universal network operating system that runs across a variety of devices. >From low cost residential CPE's with wifi to switches to BGP speaking routers. Is there anything that can do it all today? I will use something like OpenWRT as an example. I don't consider this anywhere near carrier grade, but it runs on X86 and low cost routers. I don't think it will run on whitebox switches though. Mikrotik RouterOS would be another example as it can run on low cost Routerboards, and X86 servers. But it is not opensouce. Is there any up and coming projects to look into?

survey on BGP prefix hijacking
by Alberto Dainotti 02 May '18

02 May '18

Dear NANOG Community, BGP prefix hijacking remains a problem for Internet routing, despite the (partial) use of RPKI or detection services. We would like to hear your opinions on BGP prefix hijacking (concerns, existing defenses, needs, etc.) that would help us research new defense mechanisms both for its detection and mitigation. Please help us by answering this short (< 10min, 21 questions) and anonymous survey. Survey URL: http://tinyurl.com/hijack-survey *** The survey *** This survey is part of a joint research effort by CAIDA (www.caida.org) and the ICS-FORTH (www.ics.forth.gr) research institute, to study (a) operator awareness of BGP prefix hijacking attacks/incidents, (b) presently used defenses against BGP prefix hijacking, (c) the willingness to adopt new defense mechanisms, and (d) reasons that may hinder the deployment of BGP prefix hijacking defenses. We expect the findings of this survey to increase the understanding of existing BGP hijacking defenses and the needs of network operators, as well as help us design and implement new defense mechanisms that we will present to the operator and scientific communities. A summary of the aggregate results will be published as a part of an article/conference paper. Thank you in advance, and we look forward to your responses! Alberto (CAIDA) and Pavlos (ICS-FORTH)

Remote power cycle recommendations
by Andy Ringsmuth 30 Apr '18

30 Apr '18

I’m sure many here are familiar with or using/have used devices to remotely power cycle equipment. I’m considering a Dataprobe iBoot-G2 and am curious if you’ve had experience with it, or other recommendations. I only need one outlet to be remotely power cycle-able. I have one piece of equipment that is occasionally a little flaky and, well, you know the hassle. What do people recommend? There seem to be plenty out there which are more designed to auto-reboot when Internet connectivity is lost, aka remotely reboot the ‘ol cable modem for instance, but that’s not my scenario. Thanks in advance. ---- Andy Ringsmuth andy(a)newslink.com News Link – Manager Technology, Travel & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular

Hey all, Just wondering if anyone peers with Hulu at any public exchange. I don't see anything on them in the peeringdb or anything that stands out from a google search besides it looks like they may be doing something with Equinix. Thanks

Internet topology resources
by Lars Prehn 27 Apr '18

27 Apr '18

Hi all, two quick questions: Is there any way to retrieve BGP data (e.g. table dumps, updates, ...) such that i.) the data is not already available in the RIPE RIS, Routeviews, PCH, Isolario, or BGPmon projects and ii.) it is not necessary to query a Looking Glass to death (e.g. get all neighbors, for each neighbor get all prefixes, for each prefix get all announcements)? Are there any traceroute (or related) projects that currently still make their data publically available except for MLAB, RIPE Atlas, Caida, the Bismark Projekt, the portolan project? In addition, if you know somebody that knows somebody (...) that probably might be capable of giving me access to an IXP Route Server dump, a set of traceroutes that is not published publically yet, or something related I would *really* appreciate if you could forward me the contact! :) All data is supposed to be used in a research context, more specific my master thesis, therefore I would also accept annonymized data as long as it still contains useful topology information. Best regards, Lars
