Is BGP Really that Complex?
Anyone following the popular networking blogs and podcasts is probably familiar with the claim that BGP is way too complex to be used in whatever environment. On the other hand, more and more smart people use it when building their data center or WAN infrastructure. There’s something wrong with this picture.
Every Product Needs to Scale… to a Point
Long time ago in a podcast far far away Greg and Ethan pondered whether networking solutions need to scale or not, and obviously one cannot disagree with their generic conclusion that enterprises need just-good-enough solutions and not Google-scale architectures.
However, do keep in mind that:
Using Macvlan and Ipvlan with Docker on Software Gone Wild
A few weeks after I published Docker Networking podcast, Brent Salisbury sent me an email saying “hey, we have experimental Macvlan and Ipvlan support for Docker” – a great topic for another podcast.
It took a while to get the stars aligned, but finally we got Brent, Madhu Venugopal, John Willis and Nick Buraglio on the same Skype call resulting in Episode 57 of Software Gone Wild.
The Future of Multicast and QoS
A. Friend sent me a long list of questions after listening to excellent Future of Networking podcast with Martin Casado because (as he said) he prefers “having a technical discussion with arguments and not just throwing statements out there.”
He started with “Martin's view seems to be that network is all plumbing and all the intelligence should be in the applications.”
What Is Software-Defined Security?
Gabi Gerber is organizing a Software-Defined Security event in Zurich next week in which I’ll talk about real-life security solutions that could be called software defined for whatever reason, and my friend Christoph Jaggi sent me a few questions trying to explore this particular blob of hype.
For obvious reasons he started with “Isn’t it all just marketing?”
Is XMPP Control- or Management-Plane Protocol?
My readers are consistently asking me whether XMPP and OVSDB are control- or management-plane protocols (to make matters worse, publicly available information tends to be confusing).
For example, one of them wrote…
Building a L2 Fabric on top of VXLAN: Arista or Cisco?
One of my readers working as an enterprise data center architect sent me this question:
I've just finished a one-week POC with Arista. For fabric provisioning and automation, we were introduced to CloudVision. My impression is that there are still a lot of manual processes when using CloudVision.
Arista initially focused on DIY people and those people loved the tools Arista EOS gave them: Linux on the box, programmability, APIs… However
Optimize Your Data Center: Ditch the Legacy Technologies
In our journey toward two-switch data center we covered:
It’s time for the next step: get rid of legacy technologies like six 1GE interfaces per server or two FC interface cards in every server.

OpenFlow Table-Type-Patterns and Vendor Hype
Network Computing recently published an article with a promising title “Network Disaggregation: Opening the Last Back Box” and a subtitle I could totally relate to: “switch ASICs must be opened up to provide real networking flexibility.”
Feedback: Layer-2 Leaf-and-Spine Fabrics
Occasionally I get feedback that makes me say “it’s worth doing the webinars ;)”. Here’s one I got after the layer-2 session of Leaf-and-Spine Fabric Designs webinar:
I work at a higher level of the stack, so it was a real eye opener especially with so much opinionated "myths" on the web that haven't been critically challenged such as [the usefulness of] STP.
There’s more feedback on this web page where you can also buy the webinar recording (or register for the next session of the webinar once they are scheduled).
