Help evaluate CDN
by Mehmet Akcin 01 Jun '17

01 Jun '17

Hey there I have written few blog posts about dns performance in the past comparing public resolver performance and root server performance using tools like thousandeyes. I am now working on a new blog post independently and voluntarily comparing cdn performance. I wanted to reach out to experts in the community ask feedback on what they wanted to see in such comparison. What are some of the important things like cache-hit-ratio etc. you look for when evaluating CDN performance? What categories would you like to see? Such as video performance, static images, etc. Appreciate any feedback you can share, and will make sure to thank you for your help in my post(s). I might even buy you guys beer @ nanog :) i will be in Bellevue next week if anybody prefers to talk face to face Mehmet

NCCoE Secure Inter-Domain Routing Project - request for industry input.
by Montgomery, Douglas (Fed) 31 May '17

31 May '17

The National Cybersecurity Center of Excellence (NCCoE) requests community input on a proposed project entitled: Secure Inter-Domain Routing, Part 1: Route-Hijacks. https://nccoe.nist.gov/projects/building-blocks/secure-inter-domain-routing The objective of the project is to examine and demonstrate the state of the RPKI and BGP Origin Validation technologies in realistic scenarios and to address identified concerns with their deployment and use (e.g., security, robustness, management / monitoring, multi-vendor inter-operation). This request is for industry input on the the proposed project plan. In particular we seek input from both network operators and enterprises on practical issues and barriers to adoption and suggestions for how these could be addressed in the project. Please see the link above for instructions for submitting comments and how you can join a community of interest for the project. *The intention is not to have the discussion here on the NANOG list.* Thanks dougm — Doug Montgomery, Mgr Internet & Scalable Systems Research at NIST/ITL/ANTD

BCP38/84 and DDoS ACLs
by Graham Johnston 29 May '17

29 May '17

I really did try looking before I sent the email but couldn't quickly find what I was looking for. I am looking for information regarding standard ACLs that operators may be using at the internet edge of their network, on peering and transit connections, wherein you are filtering ingress packets such as those sourced from UDP port 19 for instance. I've found incomplete conceptual discussions about it nothing that seemed concrete or complete. This doesn't seem quite like it is BCP38 and more like this is BCP84, but it only talks about use of ACLs in section 2.1 without providing any examples. Given that it is also 13 years old I thought there might be fresher information out there. Thanks, graham

Cisco NCS5501 as a P Router
by Erik Sundberg 29 May '17

29 May '17

We're at the growing point where we need a dedicated P router for a core device. We are taking a serious look at the NCS5501. Is there anyone else using a NCS5501 as P Router or just general feedback on the NCS5501 if you are using it? The big downside is it's only has a single processor I Can't justify a ASR9K or NCS5500 Chassis yet. ________________________________ CONFIDENTIALITY NOTICE: This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain confidential information that is legally privileged.

If you want to assess the dynamism or size of ACL required for a given AS, place the AS into this URL: https://spoofer.caida.org/prefixes.php?asn=1909 Matthew

What happened to BGP Update Report?
by Anurag Bhatia 27 May '17

27 May '17

Hello, everyone. I wonder if anyone is aware of what happened to BGP Update Report which was being published to most of NOG mailing lists? I see the last one is from 7th Dec 2016. BGP Update Report was the one which provided unstable origin ASNs etc. I still do see the weekly routing table report with other data. Thanks. -- Anurag Bhatia anuragbhatia.com
