This document discusses Internet of Things (IoT) networks. It describes key IoT components like sensors, gateways, and cloud infrastructure. It also outlines requirements for IoT networks to be scalable, reliable, and secure. Specifically, it recommends designs with redundancy like distributed link aggregation and virtual chassis architecture to avoid single points of failure and long convergence times during network issues. The document provides examples of network security measures that can be implemented at the physical, logical, and visibility layers.
