Fast Friday – Networking Field Day 22 Thoughts

Since I’m on the road again at Networking Field Day this week, I have had some great conversations with the delegates and presenters. A few stray thoughts that may develop into full blown blog posts at some point, but I figured I could get some of them out here for some quick entertainment.

• The startup model means flexibility. That also means you can think about problems in a new light. So it would follow that you get to develop some new idea without a mountain of technical debt. Things like archaic platforms and crusty old user interfaces. You’d be surprised the amount of stuff that gets carried forward as technical debt.
• Integrating products isn’t easy. Even if you think you’ve got the right slot for your newest acquisition you may find it isn’t the best fit overall. Or, even better, you may find a synergy you didn’t know existed because of a forgotten tool. Very rarely does anything just neatly fit into all your plans.
• The more guest Wi-Fi I have to register for, the more I long for the days of Passport and OpenRoaming. If you already know who I am, why oh why must I continually register. Who Continue reading

Multicast Routing in AWS

Consider for a moment that you have an application running on a server that needs to push some data out to multiple consumers and that every consumer needs the same copy of the data at the same time. The canonical example is live video. Live audio and stock market data are also common examples. At the re:Invent conference in 2019, AWS announced support for multicast routing in AWS Virtual Private Cloud (VPC). This blog post will provide a walkthrough of configuring and verifying multicast routing in a VPC.

Digging up IP addresses with the Linux dig command

Not unlike nslookup in function, but with a lot more options, the dig command provides information that name servers manage and can be very useful for troubleshooting problems. It’s both simple to use and has lots of useful options.The name “dig” stands for “domain information groper” since domain groping is basically what it does. The amount of information that it provides depends on a series of options that you can use to tailor its output to your needs. Dig can provide a lot of detail or be surprisingly terse.[Get regularly scheduled insights by signing up for Network World newsletters.] Just the IP, please To get just the IP address for a system, add the +short option to your dig command like this:To read this article in full, please click here

Let’s Improve Routing Security at APRICOT 2020

Internet builders in Asia-Pacific get together around this time every year at APRICOT to learn from each other and other leaders from around the world. Routing security will be a key theme, and we will be sharing in multiple sessions why the MANRS initiative is important to the global routing system.

Also called the Asia-Pacific Regional Internet Conference on Operational Technologies, the conference is the largest meeting of the technical community in the region. It draws many of the world’s best Internet engineers, operators, researchers, service providers, and policy enthusiasts from over 50 countries to learn, share, and network.

Held annually, the ten-day meeting consists of workshops, tutorials, and conference sessions, birds-of-a-feather (BoFs) sessions, and peering forums all with the goal of spreading the knowledge needed to run and expand the Internet.

Technical training workshops will run from Feb 12 to 16, and the conference itself from 17 to 21 in Melbourne, Australia.

Our team at the Mutually Agreed Norms for Routing Security (MANRS) initiative will speak at various sessions throughout the conference, including the Resource Public Key Infrastructure (RPKI) Deployathon on 17 February that I will facilitate. I will also be chairing the inaugural APNIC Routing Security/RPKI SIG on 20 February.
