Asked Brad Gorman at his ARIN workshop what stops a bad actor spoofing a sub-AS as the legit origin. One word: “Nothing. That’s a current vulnerability.” BGPSec is dead. RPKI shipped. ASPA’s shipping. Routing security in 2026: routerjockey.com/arin-chinog…

ARIN at CHI-NOG 13: The State of Routing Security

BGPSec didn't ship. RPKI did. A walkthrough of where RPKI and ROV stand in 2026, the gaps Brad Gorman's ARIN workshop exposed, and what's coming next with ASPA.

Upscale AI at NFD40: no products yet, but the best AI networking tutorial I've seen. Packet-level teardown of cloud vs AI traffic. Why RDMA isn't TCP. Why ECMP breaks with elephant flows. SkyHammer is the scale-up bet. Now they need to ship. routerjockey.com/upscale-nfd…

Upscale AI at NFD40: The Pitch Before the Product

Upscale AI's SkyHammer ASIC and scale-out strategy for AI clusters: standards-based UALink, why collective communication differs from cloud TCP, and why ECMP breaks under GPU load.

Networks Are Graphs. NetAI Acts Like It. routerjockey.com/netai-nfd40…

Networks Are Graphs. NetAI Acts Like It.

NetAI uses graph neural networks, not LLMs, for network root cause analysis. Networks have explicit structure. The math should reflect that. Deterministic causation, not statistical guessing.

AI Networks Can't Use SDN. Netris Built What's Next. routerjockey.com/netris-nfd4…

AI Networks Can't Use SDN. Netris Built What's Next.

Netris automates AI data center networks by layering multi-tenancy and distributed agents above the physical fabric. Why SDN fails at GPU-cluster scale.

AI NOC, Not AI-on-NOC: Aviz Flips the Stack

Aviz Networks shifts from bolting LLMs onto controllers to building agentic platforms with role-based guardrails, custom agents via Python SDK, and data hygiene as the first real use case.

Vendor PSA: A Field Guide to Field Day

A field guide for vendors presenting at Tech Field Day events. Read the bios, kill the NASCAR slide, send the deck afterward, and stop treating delegates like sales leads.

Ethernet Commoditizes Everything. Except EOS

Arista's pitch to the cloud is that silicon commoditizes fast. Their lock-in is EOS, CloudVision, and operational muscle memory. What that actually means for buyers.

Tim Cook is Leaving. Good.

Tim Cook built Apple's supply chain into a fortress. Apple's software got measurably worse on his watch. John Ternus has one chance to fix it.

Shameless plug: the RouterJockey store is back

RouterJockey merch is back. 'PCAP or it didn't happen' t-shirts, polos, notebooks. Higher quality than the 2015 store, fewer products, more care.
