Network switches are devices that connect multiple devices together on a computer network, using packet switching to receive, process, and forward data to the destination device. Each switch typically contains multiple ports, which are the points of connection for network cables. These ports can be in an active state, where they are ready to transmit data, or in an idle state, where they consume less power. Power consumption in datacenters has been a topic of concern due to the increasing demand for data processing and storage.

The present disclosure uses artificial intelligence to more intelligently transition ports between different modes of operation.
