Worth Exploring: NetDoc – Automated Network Discovery and Documentation
Andrea Dainese released an interesting tool that performs automated network discovery, pushes the discovered data into NetBox, and then uses netbox-topology-views plugin to create network topology diagrams.
Definitely worth exploring!

After decades trailing the rest of the world in leading-edge chip making, Chinese sand stamper Semiconductor Manufacturing International Corporation (SMIC) has quietly got into the 7nm business. That’s a huge and unexpected leap. Has the West’s embargo of the latest fab furniture failed?

Although the United States and China are not engaged in traditional warfare, they are engaged in a war of ideas, trade, and technology, especially in semiconductor hegemony, where both sides are battling for supply and advancement.

Trade was global, the world was inextricably connected, and your job’s in China now but you should thank us, actually, because everything is cheap and fast and out-of-work factory workers can simply learn to code.

Last month, CFR issued the report of a new task force, “Confronting Reality in Cyberspace: Foreign Policy for a Fragmented Internet.” (I was project director for both reports.)

Nationalism has come to software. While downloading TikTok or WeChat onto your cell phone isn’t quite tantamount to installing Huawei equipment in your local cell tower, all indications suggest that a software geopolitical divide has arrived and won’t be going Continue reading
Fun Times: Is Cisco ACI Dead?
A recent blog post by Andrew Lerner asks whether Cisco ACI is dead. According to Betteridge’s law of headlines, the answer is NO (which is also Andrew’s conclusion), but I liked this gem:
However, Gartner assesses that Nexus Dashboard Fabric Controller is the optimal fabric management software for most Cisco data center environments.
An automation intent-based system provisioning a traditional routed network is considered a better solution than a black-box proprietary software-defined blob of complexity? Who would have thought…

Heavy Networking 646: Networking For Spacefaring Rockets
Today on Heavy Networking, aerospace networking. We talk with Lexie Cooper, who works for Blue Origin as an Avionics Integration Engineer. That’s right. Lexie does networking for rockets. We talk about the challenges of building networks for spacefaring vehicles, differences between aerospace and the typical enterprise, continuous learning, the pros and cons of building a social media presence, and more.

IT/OT convergence isn’t enough. The real benefits come when network technology joins IT and OT in a powerful trifecta.Brand Protection
I woke up at 5am this morning to order a new iPhone. I did this because I wanted the new camera upgrades along with some other nice-to-haves. Why did I get an iPhone and not a new Samsung? Why didn’t I look at any of the other phones on the market? It’s because I am a loyal Apple customer at this point. Does that mean I think the iPhone is perfect? Far from it! But I will choose it in spite of the flaws because I know it has room to be better.
That whole story is repeated time and again in technology. People find themselves drawn to particular companies or brands. They pick a new phone or computer or car based on their familiarity with the way they work or the design choices that are made. But does that mean they have to be loyal to that company no matter what?
Agree to Disagree
One of the things that I feel is absolutely paramount to being a trusted advisor in the technology space is the ability to be critical of a product or brand. If you look at a lot of the ambassador or influencer program agreements you’ll see Continue reading
Improving Network Security Through Segmentation
While segmentation may seem to increase network complexity due to the additional filtering points, a good implementation will improve and simplify security.Video: Testing IPv6 RA Guard
After discussing rogue IPv6 RA challenges and the million ways one can circumvent IPv6 RA guard with IPv6 extension headers, Christopher Werny focused on practical aspects of this thorny topic: how can we test IPv6 RA Guard implementations and how good are they?

Sender Pays
The entire set of issues of network neutrality, interconnection and settlements, termination monopolies, cost allocation and infrastructure investment economics is back with us again. This time it’s not under the banner of “Network Neutrality,” but under a more directly confronting title of “Sender Pays”. The principle is much the same: network providers want to charge both their customers and the content providers to carry content to users.ExtraHop SAML Authentication with Azure AD
I was recently working with a customer to configure Azure AD as the SAML provider for their ExtraHop appliances. Although the process is pretty well documented in the ExtraHop docs, it is spread out in a few locations and there are a couple of gotchas we ran into. In this post, I...continue reading
