A network device includes one or more memories and one or more processor circuits coupled to the one or more memories. The one or more processor circuits are configured to cause providing for transmission a request directed to a network controller to change a power state of the network device, receiving a grant from the network controller in response to the request, and changing the power state of the network device in response to receiving the grant. The power state of the network device includes a running power state and a standby power state, where the standby power state includes an active mode and an idle mode. A network controller for granting a request from the network device to change a power state of the network device is also disclosed.

1. A network device, comprising: one or more memories; andone or more processor circuits coupled to the one or more memories, the one or more processor circuits configured to cause: providing for transmission a request directed to a network controller to change a power state of the network device, w
1. A network device, comprising: one or more memories; andone or more processor circuits coupled to the one or more memories, the one or more processor circuits configured to cause: providing for transmission a request directed to a network controller to change a power state of the network device, wherein the network device is configurable to change the power state between a running power state and a standby power state, the standby power state comprising an active mode and an idle mode;receiving a grant from the network controller in response to the request, andchanging the power state of the network device in response to receiving the grant,wherein: the running power state is associated with higher power consumption than the active mode and the idle mode;the active mode is associated with higher power consumption than the idle mode;in the active mode, the network device is configured to receive at least one Media Access Plan (MAP); andin the idle mode, the network device is configured to ignore MAPs. 2. The network device of claim 1, wherein the one or more processor circuits are configured to cause embedding the request in a reservation request and providing for transmission the reservation request. 3. The network device of claim 1, wherein the one or more processor circuits are configured to cause receiving a MAP, the MAP comprising the grant. 4. The network device of claim 1, wherein the one or more processor circuits are configured to cause: receiving a beacon signal; andtransitioning the network device from the idle mode to the running power state in response to receiving the beacon signal. 5. The network device of claim 1, wherein the one or more processor circuits are configured to cause: receiving a beacon signal; andtransitioning the network device from the active mode to the running power state in response to receiving the beacon signal. 6. The network device of claim 1, wherein, in the idle mode, the network device is configured to maintain a link to a network. 7. The network device of claim 1, wherein, in the active mode and the idle mode, the network device is configured to receive a beacon signal. 8. The network device of claim 1, wherein, in the active mode, the network device is configured to participate in a link maintenance operation (LMO). 9. A non-transitory tangible computer-readable storage medium storing computer-executable instructions that, when executed by one or more processors, cause one or more processors to perform operations, the operations comprising: receiving a request for changing a power state of at least one network device between a running power state and a standby power state, wherein the standby power state comprises an active mode and an idle mode; andproviding for transmission a response to the request to change the power state of power state of the at least one network device,wherein: the running power state is associated with higher power consumption than the active mode and the idle mode;the active mode is associated with higher power consumption than the idle mode;in the active mode, each of the at least one network device is configured to receive at least one Media Access Plan (MAP); andin the idle mode, each of the at least one network device is configured to ignore MAPs. 10. The non-transitory tangible computer-readable storage medium of claim 9, wherein the receiving the request comprises receiving a reservation request with the request for changing the power state embedded in the reservation request. 11. The non-transitory tangible computer-readable storage medium of claim 9, wherein the operations further comprise embedding, in the response, a grant to the request to change the power state of the at least one network device. 12. The non-transitory tangible computer-readable storage medium of claim 11, wherein the response comprises a MAP. 13. The non-transitory tangible computer-readable storage medium of claim 9, wherein the operations further comprise providing for transmission a beacon signal directed to the at least one network device. 14. A computer-implemented method, comprising: configuring a power state of a network device to be in a running power state;providing for transmission a request directed to a network controller to transition the power state of the network device from the running power state to a second power state, wherein: the second power state is one of an active mode or an idle mode,the running power state is associated with higher power consumption than the active mode and the idle mode, andthe active mode is associated with higher power consumption than the idle mode;receiving a signal from the network controller in response to the request; andtransitioning the network device from the running power state to the second power state based on the signal,wherein: when in the active mode, the network device receives at least one Media Access Plan (MAP), andwhen in the idle mode, the network device is not able to receive MAPs. 15. The computer-implemented method of claim 14, wherein the signal comprises a grant to allow transitioning the network device from the running power state to the second power state. 16. The computer-implemented method of claim 14, wherein receiving the signal comprises receiving a MAP with the signal embedded in the MAP. 17. The computer-implemented method of claim 14, further comprising: receiving a beacon signal; andtransitioning, in response to receiving the beacon signal, the network device to the running power state from one of the idle mode or the active mode. 18. The computer-implemented method of claim 14, wherein maintaining a link to a network while powering down a portion of the network device when the network device is in the idle mode. 19. The computer-implemented method of claim 14, further comprising receiving a beacon signal when the network device is in one of the idle mode or the active mode. 20. The computer-implemented method of claim 14, further comprising participating in a link maintenance operation (LMO) when the network device is in the active mode.
