Six coherent DSP houses competed in 2018. Three remain. That's not really three options. It's one option, one second-source, and a negotiating chip. Procurement teams who

Ultra Ethernet
Every major AI training cluster runs InfiniBand. The $5 trillion question is whether Ultra Ethernet will change that. The honest answer: not yet, and here's exactly where the gap is.

BGP route leaks peaked in 2019 and never went away. RPKI validates origins. It doesn't validate paths. ASPA deployment is at 3% of ASNs. Here's what PeerCortex found checking 70,000 networks.

Every network has a health dashboard. Most of them check three things: ping responds, syslog isn't on fire, BGP sessions are up. That tells you nothing about the
