Abstract
In a network including a controllable device, a method for sending a network management method to the controllable device including asserting a network management command directed to the controllable device and in response to the network management command generating and sending over the network a first number of WOL packets having a predetermined relationship to one another, followed by generating and sending over the network a second number of WOL packets, a predetermined relationship between the second number of WOL packets defining the network management command.
Claims16
An architecture for an Ethernet network comprising:
- an Ethernet switch or PHY including an externally-accessible wake-on-LAN indicator responsive to wake on LAN packets received by the Ethernet switch or PHY;
- a processor in communication with the Ethernet switch or PHY, the processor further coupled to receive the externally-accessible wake-on-LAN indicator in the Ethernet switch or PHY, the processor configured to detect and decode a network management command by analyzing attributes of the received externally-accessible wake-on-LAN indicator;
- and
- a power-over-Ethernet injector coupled to the Ethernet switch or PHY, the power-over-Ethernet injector responsive to the processor to alternately disable and enable power to an output port in response to the decoded network management command,
- wherein the attributes of the externally-accessible wake-on-LAN indicator comprise at least one of a number of successive externally-accessible wake-on-LAN indicators or groups of externally-accessible wake-on-LAN indicators, and a timing between successive externally-accessible wake-on-LAN indicators or groups of externally-accessible wake-on-LAN indicators.
