Orchestrating low-power modes in network devices
Devices, systems, methods, and processes for orchestrating and managing various lower-power modes in a variety of network devices within a network are described herein. Various network devices, such as access points may be capable of entering one or more lower-power modes of operation that utilize less electricity to operate. When initiating a lower-power mode, the various clients that the network device has been handling need to be handed off to a sibling AP nearby. However, when exiting these lower-power modes, these devices may need different amounts of time to reboot and/or resume normal operations. Thus, when deciding which clients to re-associate with the waking up network device, various considerations need to be weighed based on client needs and network device capabilities. Thus, a smart environmental controller (SEC) is utilized to coordinate these processes. The SEC can be a specialized device, or a logic distributed remotely or among the network devices.
1 . A device, comprising:
a processor;
at least one network interface controller configured to provide access to a network; and a memory communicatively coupled to the processor, wherein the memory comprises
a smart environmental controller (SEC) logic that is configured to:
establish communication with an access point (AP) via the at least one network interface controller, wherein the AP is associated with a plurality of clients;
receive AP power mode capability data;
parse the AP power mode capability data;
receive a notification that the AP will enter a lower-power mode;
receive a wake-up signal from the AP;
track a floorplan location of clients that are in an area of restoral covered by at least the AP upon waking of the AP from the lower power mode;
utilize the parsed AP power mode capability data and the tracked floorplan locations of the clients to determine which of the plurality of clients should be transferred back to the AP upon wake-up;
generate client management data based on the determined plurality of clients; and
transmit the generated client management data to the AP;
wherein the SEC is further configured to determine the clients suitable for re-association based on at least a lower-power mode type utilized by the AP upon its waking-up.
2 . The device of claim 1 , wherein the AP power mode capability data is received from the AP.
3 . The device of claim 2 , wherein the AP power mode capability data comprises one or more low power settings available within the AP.
4 . The device of claim 3 , wherein the one or more low power settings comprise at least: entering the lower-power mode, entering a hibernation mode, or powering down the AP.
5 . The device of claim 1 , wherein the client management data comprises a list of clients that should be re-associated with the AP upon wake-up.
6 . The device of claim 5 , wherein the AP is associated with one or more sibling APs within communication range of the AP.
7 . The device of claim 6 , wherein the clients to be re-associated are associated with the one or more sibling APs.
8 . The device of claim 1 , wherein the smart environmental controller logic is further configured to receive a notification that the AP has resumed normal operations.
9 . A network device, comprising:
a processor;
at least one network interface controller configured to provide access to a network;
a plurality of clients being serviced by the network device; and
a memory communicatively coupled to the processor, wherein the memory comprises a smart environmental controller logic that is configured to:
establish communication with an external smart environmental controller (SEC) via the at least one network interface controller;
generate AP power mode capability data;
transmit the AP power mode capability data to the SEC;
determine that it is suitable to initiate a lower-power mode;
transmit a notification to the SEC that the lower-power mode is being initiated;
enter the lower-power mode;
initiate wake up from the lower-power mode;
transmit a wake-up signal to the SEC, wherein the SEC performs tracking of one or more floorplan locations of clients that are in an area of restoral of the network device upon waking of the network device from the lower power mode;
receive client management data from the SEC, wherein the client management data is generated at the SEC by utilizing the AP power mode capability data and the tracked floor plan locations of the clients; and
re-establish an association with the clients indicated within the client management data;
wherein the SEC is further configured to determine the clients suitable for re-association based on at least a lower-power mode type utilized by the network device upon its waking-up.
10 . The network device of claim 9 , wherein the smart environmental controller logic is further configured to transmit a notification to the SEC that normal operations have resumed.
11 . The network device of claim 9 , wherein the AP power mode capability data comprises one or more low power settings available within the AP.
12 . The network device of claim 9 , wherein the network device is associated with one or more sibling network devices.
13 . The network device of claim 12 , wherein the smart environmental controller logic is further configured to transmit a notification to the one or more sibling network devices when it is determined that it is suitable to enter the lower-power mode.
14 . The network device of claim 13 , wherein the one or more sibling network devices can associate with and service at least one of the plurality of clients.
15 . The network device of claim 12 , wherein the smart environmental controller logic is further configured to transmit a wake-up signal to the one or more sibling devices.
16 . The network device of claim 15 , wherein the re-established clients are received from the one or more sibling network devices.
17 . The network device of claim 16 , wherein the smart environmental controller logic is further configured to receive additional clients from the one or more siblings network devices that are not indicated in the client management data.
18 . A method of orchestrating lower-power modes in network devices, comprising:
establishing communication with an access point (AP), wherein the AP is associated with a plurality of clients;
receiving AP power mode capability data from the AP;
parsing the received AP power mode capability data to determine lower-power mode capabilities of the AP;
receiving a notification that the AP will enter a lower-power mode;
receiving a wake-up signal from the AP;
tracking a floorplan location of clients that are in an area of restoral covered by the AP upon waking from the lower power mode;
utilize the parsed AP power mode capability data and the tracked floorplan locations of the clients to determine which of the plurality of clients should be transferred back to the AP upon wake-up;
generating client management data based on the determined plurality of clients; and
transmitting the generated client management data to the AP; and
configuring a SEC to determine the clients suitable for re-association based on at least a lower-power mode type utilized by the AP upon its waking-up.
