At Networking Field Day 39, Tom Hollingsworth explored how AI, automation, and secure design are redefining enterprise networking. From agentic AI accelerating root cause analysis and automated remediation, to Graphiant’s overlay network-as-a-service strengthening data governance without sacrificing privacy, to Cisco’s focus on the front-side fabric that keeps AI clusters running efficiently, to Nokia's Event-Driven Automation—these innovations highlight a shift toward smarter, more adaptive infrastructure. The future of networking isn’t just faster—it’s more intelligent, resilient, and securely interconnected.
