Working together, for the Internet of tomorrow. The North American Network Operators’ Group (NANOG) is a 501(c)3 nonprofit tech organization committed to the ongoing advancement of an open, secure, and robust Internet.
Learn, connect, inspire. Through education + outreach, conferences + events, NANOG offers students and working professionals in computer science and network engineering, operations, and architecture a platform to share the latest Internet technologies and industry best practices, and the tools and resources they need to meet the ever-changing demands of a global network.
BGPStream was used to show BGP prefix hijacking events. Now, with the use of this platform, has this functionality been discontinued? How can I view these historical records?
In 1996 in Karachi, Pakistan I connected to a BBS and downloaded a 14K image of Bart Simpson that took around 90 seconds. I was 16. My late father insisted on buying me a computer so I could learn about the ways of the new world! Babajan you were a superstar!
I think he is mistaken regarding an individuals ability to steer and influence an organization. It is hard to move an elephant and also many are not in a situation to be bold enough to get it going. Most people need to keep their jobs (not take risks) and not rock the boat.
The speaker achieves full throughput at a Gbit and also claims there is no packet loss at that speed. There is. Or there is nearly infinite delay in the stack. Loss is a required signal for that for cubic. BBR on the other hand estimates round trip delay.
Good presentation, but he is wildly out of touch about setting up a virtual data center deployment. Virtualization has never been easier with tools like containerlab. I don't know anyone still buying Cisco 1921s and Cat 3750s on eBay to build a lab anymore..
Very interesting presentation on current optical communication technologies and their real world applications. Just a small remark, at 0:9:44 the speaker probably meant to say Terahertz (THz) in place of Gigahertz (GHz). As Channel13 = 191.3 THz, in DWDM ITU-T grid channels
I think it might be better terminology to use term "fronthaul" for in premise "transit" networks which are from the OSP demarc (e.g. Cable MODEM) to the per room radio heads. Backhual is too confusing here, at least to me. Then there are three fronthaul choices in priority order, fiber fronthaul, copper fronthaul and wireless fronthaul. Copper & ethernet is going got top out at 10Gb/s. The signal loss of 100Gb/s over copper is in dB per inch, roughly 4 meters for a passive cable. Signal loss over fiber is .5db per kilometer and is independent of modulation and will scale to petabits/sec. So, make sure while you're installing communications fronthaul conduits to consider future fiber pulls too. The per room location doesn't really need a wall outlets as the fiber can be connected to wireless radio in the ceiling. It's sorta analogous to irrigation systems where the physical aspects of the landscape and plants should influence both the sprinkler heads placements and how the PVC is laid and zoned. Placing the radios (and antennas) properly and using a proper fronthaul design will help a lot.
Individual flow through a queue can be categorized as a micro-flow (based on ip tuple) which could then individually be monitored for good behaviour (Queue Protection).
Great talk, as always. The linearity of IPv6 growth isn't because of unhealthy (lack of) growth; it's because we are in the linear portion of the logistic growth. We are past the point of the exponential growth. You're absolutely correct that most traffic for most hosts most of the time isn't going across the planet. But we still have the long tail ... and we must preserve the long tail to fight an overly monopolistic nature of the net
We actually did that first because it allowed us to use something simple like ping-plotter. What we knew intuitively (but can now prove since extending Pingo to IPv6 following this talk) is that IPv6 and IPv4 frequently take vastly different paths across the internet. They're very much separate protocols and are hashed completely separately. It's not at all unusual to see an IPv4 and IPv6 ping between the same two points on the same two circuits have 100ms+ delta in latency. There's also the fact that it's very hard sometimes to get Tier1's to take you seriously when the traffic you're trying to troubleshoot is ICMP. For various reasons, UDP works a bit better.
Shame NANOG for allowing this silly cryptocurrency-promotion. None of what is proposed here is of any use. In a "permissioned" system a blockchain is at best a detail, and likely a very poorly performing database. Just use postgres! In a "non-permissioned" one you need a crytpo coin (to fund it / pay miners), and with proof-of-waste you're pouring petrol on our climate woes. Below vid is well worth a watch if anyone doubts. Sigh. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tspGVbmMmVA.html
