Must Read: Impact of Tomahawk-4 on Data Center Fabric Designs
Dinesh Dutt, a pragmatic IP routing guru, the mastermind behind great concepts like simplified BGP configuration, and one of the best ipSpace.net authors, finally decided to start blogging. His first article: describing the impact of having 256 100GE ports in a single ASIC (Tomahawk 4). Hope you’ll enjoy his musings as much as I did ;)

Member News: Internet Society Chapters Focus on Security
Security on your mind: The Internet Society’s Chapter in Benin recently hosted a conference focused on online security and on connectivity issues. Much of the discussion focused on instability of connections in the country, with participants concerned about degraded connections. Participants also talked about limited coverage for mobile services. On the topic of security, speakers urged Internet users to regularly change their passwords, avoid default passwords, and prevent third-party apps from connecting to the services they use.

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
Podcast: BGP in Public Cloud Revisited
After my response to the BGP is a hot mess topic, Corey Quinn graciously invited me to discuss BGP issues on his podcast. It took us a long while to set it up, but we eventually got there… and the results were published last week. Hope you’ll enjoy our chat.
I talked about (lack of) network security in How Networks Really Work webinar. I’ll cover similar topics in the Upcoming Internet Challenges webinar.

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.
