Intent-Based Networking

Intent-based networking changes what an operator hands the network. Instead of specifying how — the configs, the routes, the per-box CLI — you declare the what: the outcome you want, like "keep this slice under 10 ms with five-nines availability." The system translates that intent into concrete configuration and policy, pushes it out, and then keeps checking reality against the goal, adjusting on its own.

That continuous-verification part is what separates real IBN from a fancy provisioning script. It's a closed loop: the network doesn't just apply the intent once, it watches whether the outcome is actually being met and corrects drift. The appeal is obvious as networks get too complex and too fast-moving for humans to hand-tune, but the hard problems are equally real — expressing intent unambiguously, translating it reliably across multi-vendor gear, and trusting the system to act without a person in the loop. It's a cornerstone of where automation frameworks like ZSM are headed.
