Heavy Networking 664: Semantic Networking – Science Project Or Networking’s Future?
Today’s Heavy Networking is a forward-looking episode about semantic networking. Semantic networking operates at the packet level and aims to make decisions on how to route packets based on more than just the destination address. The goal, according to an IETF draft on semantic networking, is to “facilitate enhanced routing/forwarding decisions based on these additional semantics to provide differentiated forwarding paths for different packet flows distinct from simple shortest path first routing.”
One of the questions around semantic networking is how to add these semantics to a packet: by adding fields to an IPv6 header, adding more information to existing fields, or by adding semantics to the IP address itself.
Our guests and guides to semantic routing are Adrian Farrel of Old Dog Consulting and Hannes Gredler, CTO at RtBrick.
* The definition of semantic routing
* Semantic routing examples, including Source/Destination Address Routing (SADR) and Segment Routing
* Why the industry might want semantic routing
* Incorporating semantic routing into existing practices and standards
* How to program routers to work with semantic information
* Who actually wants this?

Network Break 415: WAN Update Severs Microsoft Cloud Services; Intel To Wind Down Network ASIC Biz
Take a Network Break! This week we discuss new capabilities in Juniper’s Astra data center automation software; a major Microsoft outage that affected Outlook, Teams, and more; and reports that Intel will discontinue selling the Tofino programmable ASIC.
The US Justice Department and international law enforcement agencies partner on shutting down a ransomware site, Intel loses $661 million in the fourth quarter of its fiscal year, and Microsoft anticipates customers will spend less on cloud computing going forward.
Extreme Networks reports second quarter financial results and says farewell to its CFO, and Nokia sees significant growth in enterprise sales.

Heavy Networking 663: OpenAI For Networking
Would you give an artificial intelligence responsibility to write your router configurations? You wouldn’t. Not yet. But we’re not as far from that as you might think. For example, I gave the OpenAI tool ChatGPT the following prompt:
“Generate a Cisco router configuration for two routers using OSPFv2. The first router should be in OSPF area 0. The second router should be in OSPF area 1. Area 1 is a stub area. The OSPF neighborship should form securely using keys.”
The result was far from perfect…but it wasn’t a bad place to start. The AI had learned enough to know what I was asking for. The config it generated was missing some syntax and some dependencies, plus it added a few things I didn’t ask for like “redistribute static” and “default-information originate”.
But it’s not hard to see how, given the right training on a narrowly scoped data model, the AI could indeed generate robust, usable configs. Our skill as engineers would be in the prompting–knowing what to ask the AI for to generate the configuration. I don’t even think this is that far off, considering where ChatGPT as a tool is today.
Our guests are Ryan Booth and Phil Gervasi, both repeat voices here on Heavy Networking. They are employed by networking vendors you’ve heard of, and have been digging into the state of AI and its usefulness to networkers.

Greg’s “Fart” and “Centaur” Metaphors Earn 5 Stars
First NB episode of 2023:
Greg compares the ability to spot someone using a ChatGBT result as akin to being able to identify the guilty party in a silent but violent offense. 😆
Later in the episode, he compares the body of a Centaur to an AiOps model. 🤯
Been listening for years, great podcast, great group of gents. Keep ‘em coming! 🤘🏼
Great for a beginner like me
I’ve been listening for about a year now and great for me morning and afternoon commute.
I’m just getting into the IT world after working in OT (manufacturing automation) for a while. This keeps me up to date on the latest news and gives me technology topics to looks up later and provokes some thought. :)
Must listen if you’re in networking
Great podcast but but take some of the opinions with a grain salt
