Variety, On The Media, don't understand the Internet

Or I don't. Which is not completely impossible. In this piece: http://variety.com/2013/digital/news/netflix-puts-even-more-strain-on-the-i… they suggest that Akamai and other ISP-side caching is either not affecting these numbers and their pertinence to the "backbone" at all, or not much. Did they miss something? or did I? Cheers, -- jra -- Jay R.

Call for papers / DENOG5
by Hibler, Florian 16 May '13

16 May '13

Dear NANOG list, I just checked with grizz, before posting this request here. ****** DENOG 5 - Call for Participation and Papers The fifth meeting of the German Network Operators Group (DENOG) will be held in Darmstadt, Germany on the 14th of November 2013. We are pleased to hereby invite applications for presentations or lightning talks to be held at this event. General Information =================== DENOG is a community for professionals within Germany who are operating, designing or researching the Internet. It provides a technical forum where those working on, with and for the Internet can come together to solve problems with every aspect of their (net)work. The meeting is designed to provide an opportunity for the exchange of information among network operators, engineers, researchers and other professionals close to the network community. More information about DENOG (in German) can be found at http://www.denog.de/ Information about the meeting will be published at http://www.denog.de/meetings/ Meeting Countdown ================= What When ------------------------------------------------------ Publication of Call for Papers April 18th, 2013 Deadline for all submissions June 19th, 2013 Publication of final program August 16th, 2013 Deadline for receipt of final present. November 8th, 2013 Meeting Day November 14th, 2013 Topics for Presentations/Talks ============================== The day will be divided into several sessions. The number and length of presentations per session is not fixed, although due to time constraints we would prefer the length of the presentations to be between 15 to 30 minutes. However proposals whose subject fall outside of the topics below are also welcome; please do not hesitate to submit them. Topic #1: Virtual network infrastructure --------------------------------------------------- "Clouds" are everywhere. Virtualization is the way to consolidate servers and lower the cost as well as the administrative overhead. But what about virtualizing network infrastructure like routers, firewalls, etc.? We see certain approaches of these technologies on the market now. Which company would be the right target? How does it scale? Topic #2: Issues affecting the global internet infrastructure ------------------------------------------------------------- Cyber attacks, software bugs, route-hijacking incidents and denial of service attacks are common in todays internet, not only affecting single companies, carriers or enterprises but sometimes even entire countries. One of the examples was Cloudflare in March 2013. What was really affected? Was it "a global issue"? In this light securing the global internet infrastructure is a major topic amongst entities relying on the internet. Topic #3: Peering ------------------ Everything about your peering experience. Why are you doing it? How are you doing it? Have you written any useful tools which others might find interesting? What are the issues you are facing? Topic #4: Network & resource planning --------------------------- Around the world we see large companies consuming lots of bandwidth for new media services like YouTube, Netflix, Akamai etc. Forecasting and planning of capactiy is an essential part of quality assurance to keep your users/subscribers happy. What are the best techniques to evaluate traffic levels to certain providers? How to manage the flow of traffic in the best way under the aspect of commerical and engineering views? Topic #5: ISP BOF ----------------- "All things ISP". From Network/SLA Management (for or against it), abuse handling and log systems to data centre layout and planning (including power and cooling), everything that is interesting to you as an ISP can be presented or discussed within this topic. Lightning Talks --------------- In addition to the topics mentioned below we will reserve slots for lightning talks, which consist of a few slides and will not last longer than 5 minutes. Lightning talks can be submitted until November 8th, with the deadline for submission of the corresponding slides being November 13th. Language of Slides and Talks ============================ To appeal to an international audience we ask you to produce your slides in English, but the spoken language of the presentation itself can be either German or English. Submission Guidelines ===================== All submissions must have a strong technical bias and must not be solely promotional for your employer. Please remember that your presentations should be suitable for a target audience of technicians from varied backgrounds, working for companies whose sizes may vary considerably. To submit a proposal for a presentation, we request you to register at http://pc.denog.de/denog5/cfp If you have further questions, you can reach the program committee at denog-pc(a)denog.de. We also welcome suggestions for specific presentations which you feel would be valuable to the DENOG community. Please be aware that your presentation and a video of it will be published on the DENOG website after the event. For the DENOG programme committee, Florian Hibler

Spamcop Blacklist
by Clinton_Popovich＠McAfee.com 15 May '13

15 May '13

Anyone- We are having a bit of trouble with spamcop blocking 2 of our MTAs with IPs of 208.65.145.71 and 208.65.145.66. We have yet to receive any samples of the spam and do not seem to be able to submit for removal as it appears someone has attempted to do this for us and basically used up all our our requests for a period of time. Does anyone have a contact over at spamcop that might be able to assist us in removing these MTAs before this becomes a large issue or us and our customers? Below is the Bounce message we are receiving. Bounce message 554 Service unavailable; Client host [pXXcXXoXXX.mxlogic.net] blocked by bl.spamcop.net Just to let everyone know, we do vigorously monitor outbound spam traffic and take seriously any reports of spam from our network. If someone can get us a sample of what spamcop is see this would also help! Any help is greatly appreciated. Thanks, -- Clinton Popovich Linux Systems Administrator McAfee 9781 S.

Looking for Netflow analysis package
by Erik Sundberg 15 May '13

15 May '13

Does anyone know of a netflow collector that will do the following. *Graph/List Destination Networks By Top AS *Graph/List Destination Networks By Top IP Address *AS Path Analysis *Traffic Type (ICMP, TCP, UDP, IPSEC, HTTP, SSH, SMTP, etc..) We will be using this to help us decide who to Peer with and what transit Providers to look at. I am familiar with Arbor Network's Peak Flow utility but it's a little too pricy. I also found AS-Stats https://neon1.net/as-stats/ look promising from the power point on their page.

Borrow request (Chicago): Cat 4900M copper interface(s)
by ryan＠u13.net 15 May '13

15 May '13

Hello all, I'll spare you the details, but we are in need of some means to temporarily get a copper interface on at least one of our 4900M switches to narrow down a network performance issue. Does anyone have a 4900M half card with copper ports, or a Cisco TwinGig X2 adapter in the Chicago area? We would love to borrow one or two for a few days until we can locate and resolve this issue.

The BGP Visibility Scanner
by Andra Lutu 15 May '13

15 May '13

Dear all, We have built a tool that checks the visibility of IPv4 prefixes at the interdomain level. The tool is available at *http://visibility.it.uc3m.es/* and you can use it to retrieve the Limited Visibility Prefixes (LVPs) (i.e., prefixes that are not present in all the global routing tables we analyse) injected by a certain originating AS. The query is very simple, it just requires to input the AS number for which you want to retrieve the originated LVPs, if any. After checking the limited-visibility prefixes, we would appreciate any feedback that you can provide on the cause of the limited visibility (we provide a form with a few very short questions which you could fill in and submit). Using a dataset from May 2nd 2013, we generated a list with the ASes which are originating LVPs: *http://visibility.it.uc3m.es/fullASlist.html* We would like to hear from any operator who might find this project interesting, and, in particular, from these large contributors to the LVPs set. Please note that advertising prefixes with limited visibility does not mean that the originating AS is necessarily doing something wrong. The ASes might be generating the LVPs knowingly (e.g., scoped advertisements). However, there might be cases where the origin AS might be unaware that some prefixes are not globally visible (when they should) or that others are leaking as a consequence of mis-configurations/slips. Our purpose is to spread awareness about these latter phenomena, help eliminate the cause of unintended/accidental LVPs and upgrade this tool to an anomaly detection mechanism. For more information on the definition and characteristics of a Limited Visibility prefix, please check the Frequently Asked Questions section of the webpage, available here: *http://visibility.it.uc3m.es/Q_and_A_latest.html* The tool works with publicly available BGP routing data, retrieved from the RIPE NCC RIS and RouteViews Projects. The results are updated on a daily basis. For more information on the methodology we refer you to the slides of the NANOG57 presentation about the BGP Visibility Scanner: http://www.nanog.org/meetings/nanog57/presentations/Wednesday/wed.general.L… Also, you can check the RIPE labs article about the BGP Visibility Scanner, available here: https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner We are looking forward to your feedback! Thank you, best regards, Andra
