Abstract: According to example implementations, a power source device provides power to a powered device over a network link. The power source device may include a controller and a transceiver configured to transmit and receive data via a network link with the powered device. The controller may be configured to receive one or more network data packets from the powered device indicating a network delay associated with the network link, determine an amount of power to be supplied to the powered device based on the network delay indicated by the one or more network data packets, and control a power supply to supply the determined amount of power to the powered device through the network link.
