Provider Suggestions for Diverse 10g Wave CHI-NJ
by Josh Niec 23 Jan '20

23 Jan '20

Hey Nanog, Could anyone suggest providers for a diverse/alternative 10g wave service between Equinix in Chicago and Equinix in New Jersey (northeastern part of the state)? Currently we have a 10g wave service via the infamous Spread Networks low-latency path between the two locations, but are looking for a second that is completely diverse with no overlaps between the two data centers. Our current provider is Crown Castle Fiber, and half of the segment, from the Ohio area to New Jersey, is leased from Zayo (who purchased Spread) by CCF. I want diverse carriers for this other path, so Zayo/CCF are not an option. I’ve checked with CenturyLink/Level3 who are unable to provide a completely diverse path. I have also reached out to Verizon who have been dragging me through a 3 month+ long process with no proposals so far (they wanted me to sign the contract before showing me the actual route of the circuit, with no guarantee that it wouldn’t overlap).

A survey on performance diagnosis for Network functions/middleboxes
by Yu, Minlan 22 Jan '20

22 Jan '20

Dear Nanog community, Today's networks (data centers, ISPs, and enterprises) all run many hardware middleboxes and software network functions. The performance of these components is critical for network management and user experiences. However, when performance problems happen, it often takes a lot of human efforts to instrument and debug these systems especially when many network functions interact with each other and with traffic dynamics. We are a group of researchers from Harvard and AT&T who are building new diagnosis tools that can automatically find potential root causes for performance problems in network functions (especially those tail latency problems that are hard to diagnose). We're reaching out to the NANOG community to understand the performance problems you have seen and your needs on diagnosis tools. This will greatly help us to incorporate your needs in our tool. We plan to release our debugging tool for the community to use. We greatly appreciate your help in filling out the survey below. It should take less than 10 minutes to complete. The survey and the collected data are anonymous (so please do *not* include information that may identify you or your organization). All questions are optional, so if you don't like a question or don't know the answer, please skip it. In the survey, we use network functions as a general term to represent both hardware and software middleboxes. A summary of the aggregate results will be published as a part of a scientific article later this year. Survey URL: https://docs.google.com/forms/d/e/1FAIpQLSdx1j2BZzk_iEuIqHLDF20Rv_LuxLcrGze… We would also be extremely grateful if you could forward this email to any operator you know beyond this NANOG mailing list.

5G roadblock: labor
by Michael Thomas 21 Jan '20

21 Jan '20

https://www.politico.com/news/2019/12/29/big-barrier-trump-5g-america-089883 An interesting article on the road to 5G that they need to about double the size of the workforce to roll it out. I expect that this affects some of you directly. But one of its premises seems a little shaky to me: has the US ever led the pack rolling out new network technology? I always thought it was Japan and South Korea that were years ahead of us. In silicon valley and SF it's still very rare to see FTTH. I'm not sure why we would expect to get to 5G any faster than we normally do. Mike

Internet services in Antarctica
by Ask Bjørn Hansen 20 Jan '20

20 Jan '20

Hi, I have a hobby project running DNS service to people looking for NTP public servers. I noticed that the DNS servers apparently get ~5 thousand queries per day from IPs that the GeoIP database we use claim are in in Antarctica. It’s less than 0.0001% of the overall DNS queries, but it made me curious what it’d take to make the service work better there. I imagine the internet service is fragmented between the various stations with each being best connected to a particular country? Does anyone have contacts there that I could talk to? I imagine (some of?) the stations would have a local NTP service as part of their compute facilities. Ask

DDoS Mitigation Survey
by Lumin Shi 20 Jan '20

20 Jan '20

Dear NANOG members, I am a senior Ph.D. student at the University of Oregon (UO). We are seeking your help to understand DDoS mitigation techniques toward volumetric link flooding attacks. With our preliminary survey so far, DDoS mitigation approaches in the real world include 1) DDoS mitigation service providers (e.g., Akamai, Cloudflare), 2) Remotely-Triggered Black Hole (RTBH), 3) BGP FlowSpec, and 4) direct contact with upstream providers for traffic filtering. We also realize the traffic filtering space in hardware routers is limited as router vendors use CAM/TCAM to implement packet matching and access control lists at line rate. We believe that many routers on the Internet today may not have the necessary capacity to perform fine-grained traffic filtering, especially when facing a large-scale DDoS attack with or without IP spoofing. To this end, we ask that you kindly participate in our short and anonymized survey at https://oregon.qualtrics.com/jfe/form/SV_03aPeCIGiyUt6st. The purpose of this survey is to understand 1) the frequency and scale of DDoS attacks, 2) the DDoS mitigation methods commonly used by the edge network operators, and 3) the capability of the mitigation methods. We plan to collect responses for three months, and we will report the survey result back to you. This study is part of our on-going research project, the Catch-22 attack, and you can view our poster paper at https://luminshi.github.io/assets/papers/catch22.pdf.

Looking for topology mapping validation
by Kévin Vermeulen 20 Jan '20

20 Jan '20

Hi NANOG, Our teams at Sorbonne Université and Naval Postgraduate School have developed a new Internet topology mapping tool, Diamond-Miner. Diamond-Miner[3] combines Paris Traceroute Multipath Detection Algorithm[1] and high probing rate Yarrp[2] techniques to trace the load balanced paths at Internet Scale. We are seeking now some validation of our inferences, in particular the traceroutes links that we have found. We have developed a small website for operators to provide validation: http://heartbeat.planet-lab.eu:8000 You can either publicly submit the validation on the website or send us an email to kevin.vermeulen(a)sorbonne-universite.fr . You will find all the details on the website, do not hesitate to ask if you have further questions. Thanks in advance, Kevin [1]: https://arxiv.org/pdf/1809.10070 [2]: http://rbeverly.net/research/papers/yarrp-imc16.pdf [3]: https://www.usenix.org/conference/nsdi20/accepted-papers

cisco nexus 9000 cctrl ERROR
by Scott Weeks 17 Jan '20

17 Jan '20

I don't have a login to cisco to find out what this is and I'm having trouble finding anything about it in search engines that doesn't require a login to cisco. I guess they only want certain folks to know about it... :( Does anyone know anything about this and can explain it to me? If not, I'll go join cisco-nsp and ask there. %KERN-3-SYSTEM_MSG: [65292299.903992] - kernel %KERN-3-SYSTEM_MSG: [66730914.839059] cctrl ERROR: cctrl_wait_for_pmbio_busy_status NACK error tmp_data 3b19600 - kernel %KERN-3-SYSTEM_MSG: [67511639.312284] cctrl ERROR: cctrl_wait_for_pmbio_busy_status NACK error tmp_data 1b18100 - kernel Those last numbers after tmp_data repeat over and over. Thanks! scott
