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.
