Abstract: Methods, systems, and computer readable media may be operable to facilitate client device band steering based upon deep packet inspection information. An access point may be configured to steer one or more client devices from a low frequency band to a high frequency band, and vice versa, based on the status of the low frequency band and/or high frequency band and the client devices associated with the bands. The access point may perform a deep packet inspection of data packet traffic associated with each associated client device, and may classify each client device as either a device associated with a media session or a device that is not associated with a media session based upon information retrieved from the deep packet inspection. The access point may choose one or more client devices to disassociate from a frequency band based upon the media session classification of the client devices.

Abstract: A communications network is provided for a water treatment system. A controller is in communication with a plurality of network elements using digital communications. The network elements have a connection configured to connect the network element to the controller or another network element. The controller sends a message to the network elements to configure the network elements for communication with the controller.

If the network address is a default address, configuration information is sent to the network element for communication on the network. If the network address is not a default address, communication is established with the network element. Messages sent from the controller to a network element having a network address not matching the network address of the network element are sent over the network to a next network element.
