Everyone is obsessing over building giant gigawatt AI data centers, but the future of inference could actually be sitting inside old telecom central offices. 🏢⚡️ New blog post here: www.bitsinflight.com/ai-inference...
AI Inference Doesn't Need New Data Centers
Training does. Inference can live in buildings we already have.

Every network engineer has a telecom procurement horror story. Lightyear showed up at #NFD40 and made a case to fix it. Their "Telecom Operating System" covers procurement, inventory and expense management, all in one tidy SaaS bitsinflight.com/lightyear-nfd40-buying-bandwidth/
Lightyear @ NFD40: Buying Bandwidth Shouldn't Suck
Every network engineer has a telecom horror story. Lightyear's Telecom Operating System is trying to fix that with software that automates the full telecom lifecycle.

@AristaNetworks's #NFD40 session gave us a very useful AI networking framework. Check out what they are doing with Networking for AI including Ethernet Scale Up Networking (ESUN), Extra-Dense Pluggable Optics (XPO) and more in my new blog: bitsinflight.com/arista-nfd40-modern-fabrics-for-ai/
Arista @ NFD40: Modern Fabrics for AI
AI networking, much like everything else in the space, is developing very quickly and has what feels like a new acronym per day. Between UEC, ESUN, NCCL and a bunch of other protocols/technologies, it...

Getting an education on XPO optics from Vijay Vusirikala from Arista Networks. This density is insane! #NFD40
Have heard a lot from all the vendors building networking for AI at #NFD40. Brendan from Arista Networks is doing a great job of breaking down the different architectures and the Arista differentiators.
Here we go! Tune in to see what Arista Networks is up to, we start in about 5 minutes (4/9 8a PT) #NFD40 techfieldday.com/event/nfd40/

LLMs and AI are Processing Data Telemetry Overnight 📊 🧠 Jason Gintert talks about a powerful use case for LLMs in network operations: overnight data processing. #TFDPodcast #NFD40 #Networking #LLMs #DataTelemetry #DataProcessing #NetworkData
It's interesting how @nokia.bsky.social is positioning their validated design guides as a product that gets a support life and that gets yearly updates. That's a far cry from many vendors that create a validated design and then ignore it for a decade. #nfd40
Guess who is in San Jose for #NFD40? This guy ✋ See presenters and presentation times here: techfieldday.com/event/nfd40/ To stream the event live, watch here: youtube.com/@techfieldday Or at the main event page above. Use #NFD40 to ask any questions you have of the presenters. So stoked!
Had a blast joining @pjwelcher.bsky.social, @scottrobohn.bsky.social & @networkingnerd.net on this @techfieldday.com podcast. What are the biggest challenge you encounter when dealing with network telemetry in your network? 🤔

The Network as a Whole
In 1980, a quantum physicist named David Bohm published a book that had absolutely nothing to do with network engineering. Wholeness and the Implicate Order argued that reality isn't a collection of ...

Got my brand spankin new #Autocon challenge coin! It got an upgrade, this guy is thick. I just can't put into words how much I enjoy this conference. The community that rallies around this organization, event and mission is remarkable. #networkautomationforum #autocon4
Hoping to get another one of these babies this week! Also anticipating some amazing presentations and conversations. Anyone else going to Network Automation Forum’s #Autocon4 in Austin?! If so, let’s meet up! Send a DM and we’ll connect. I’m attending Weds-Fri and am so excited.

Wonder what the @usnua.com is all about? I had the opportunity to talk about it in the spring at #NFD37. Here's a run down from @networkingnerd.net with a video of the presentation. Thanks to Tom and @techstronggroup.bsky.social for the platform to spread the word! techstrong.it/itsm/meeting...
Meeting Community Needs With the USNUA - Techstrong IT
Jason Gintert saw that so many disciplines in enterprise IT had user group meetings but for some reason networking was left out in the cold.

Behold, the Cisco FastHub 108T from 1997 - when 100Mbps shared bandwidth was cutting-edge and we lived without VLANs or auto-negotiation. Almost 30 years later, this single collision domain relic really shows how spoiled we've become with modern networking. (Yes, that's an OUI transceiver on top 🙂)
