For network engineers that means an agent that designs a topology, generates per-vendor configs, deploys to real network OSes, validates on live CLIs, and fixes what's broken. Here's how agentic differs from assistive AI, and where it fits in the toolchain.

AI Network Testing in 2026: What AI Can Actually Do in a Network Test Lab
Ask how AI helps with network testing and you'll hear about telco assurance and AI-written test scripts. The third lane is the interesting one: an agent that builds the lab, generates the test plan, runs iperf3/tc/convergence tests itself, and reports — end to end from plain English.
