Abstract: A first network device may provide a link discovery message to a second network device, and may identify a link based on the link discovery message. The first network device may provide, to the second network device, a first control channel message that identifies the link at the first network device, a current state of the link as a power on state, and a desired state of the link as a power sleep state, and may receive, from the second network device, a second control channel message that identifies the link at the second network device, the current state of the link as the power on state, and the desired state of the link as the power sleep state. The first network device may place the link in the power sleep state based on the first control channel message and the second control channel message.

Abstract: A network device may receive packets, wherein the network device includes a first routing component, a second routing component, a first forwarding component, a second forwarding component, and a physical interface card concentrator with multiple physical interface cards. The first routing component may provide, to the physical interface card concentrator, a signal indicating that the second forwarding component is to be an active forwarding component. The physical interface card concentrator may cause, based on the signal, a data path for the multiple physical interface cards to be switched from the first forwarding component to the second forwarding component. The first routing component may provide the packets to the second forwarding component. The second forwarding component may provide the packets to the multiple physical interface cards via the data path. The multiple physical interface cards may forward the packets toward destinations associated with the packets.

Abstract: A first network device may generate a first protocol data unit (PDU) identifying a request to transition from a power on state to a power sleep state, and may provide the first PDU to a second network device. The first network device may receive a second PDU identifying a link of the second network device to transition from the power on state to the power sleep state, and may generate a third PDU identifying a link of the first network device to transition from the power on state to the power sleep state. The first network device may provide the third PDU to the second network device, and may transition the link of the first network device and the link of the second network device from the power on state to the power sleep state based on the second PDU and the third PDU.

Abstract: A device may receive a traceroute request for a path between two edge devices of a network, and may generate a response indicating a bit cost and an energy efficiency identifier associated with the device. The device may provide the traceroute request to a plurality of network devices associated with a path between the two edge devices, and may receive a plurality of responses indicating respective bit costs and energy efficiency identifiers associated with the plurality of network devices. The device may generate a traceroute response that includes the response and the plurality of responses, and may provide the traceroute response to one of the two edge devices to indicate, to the one of the two edge devices, an energy efficiency associated with the path.
