An embodiment may include circuitry to be included, at least in part, in at least one node to be used in a network. The circuitry may (a) receive, at least in part, via at least one power supply line of the at least one node, at least one packet, and/or (b) issue, at least in part, via the at least one power supply line, the at least one packet. The at least one packet may request at least one change, at least in part, in at least one power consumption state of at least one portion of the at least one node. Many modifications, variations, and alternatives are possible without departing from this embodiment. |

1. An apparatus to be used in association with at least one node to be used in a network, the apparatus comprising:
a first circuitry to:
receive, at least in part, via at least one power supply line of the at least one node, at least one packet to request at least one change, at least in part, in at least one power consumption state of at least one portion of the at least one node; wherein:
the at least one change comprises transitioning, at least in part, among multiple mutually different power consumption states of the at least one portion, the multiple mutually different power states comprising more than two relatively different power consumption states of the at least one portion;the first circuitry is to generate, at least in part, at least one other packet to be communicated, at least in part, to at least one other node, the at least one other packet including availability status information to indicate, at least in part, availability status of a network interface controller circuitry of the at least one node;in response, at least in part, to the at least one other packet, the at least one other node is to:
communicate with the at least one node via at least one power supply line of the at least one other node;power-off, at least in part, at least one switch port of the at least one other node that is no longer to be involved in active communication with the network interface controller circuitry;the first circuitry is to be comprised, at least in part, in:
at least one switch node to be communicatively coupled to a plurality of server nodes, the at least one switch node to be communicatively coupled to at least one of the server nodes via both the at least one power supply line of the at least one other node and at least one network communication link;the at least one power supply line of the at least one node and at least one other signal line are comprised, at least in part, in at least one daisy-chained interface that is daisy-chained between the server nodes so as to permit power to be supplied to the server nodes via the at least one daisy-chained interface. |
