US 2018/0123916 A1 · BAND STEERING USING DEEP PACKET INSPECTION

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.

Dependent claims

A method comprising:

monitoring the status of one or more frequency bands;
determining that a condition exists for disassociating one or more client devices from a first frequency band, wherein the condition is based upon the monitored status of the one or more frequency bands;
identifying one or more client devices associated with the first frequency band;
determining whether each respective one of the one or more client devices associated with the first frequency band is associated with a media session, wherein the determination whether a respective one client device is associated with a media session is based upon characteristics of one or more packets being output to the respective one client device, wherein the characteristics are retrieved through a deep packet inspection of the one or more packets;
identifying at least one client device from the one or more client devices associated with the first frequency band, wherein the at least one client device is identified based upon the determination whether the at least one client device is associated with a media session;
and
disassociating the at least one identified client device from the first frequency band.

4 more elements

An apparatus comprising:

one or more interfaces configured to be used to provide a first frequency band and a second frequency band to one or more client devices;
one or more modules configured to:
monitor the status of one or more frequency bands;
determine that a condition exists for disassociating one or more client devices from the first frequency band in favor of steering the client device to an association with the second frequency band, wherein the condition is based upon the monitored status of the one or more frequency bands;
identify one or more client devices associated with the first frequency band;
determine whether each respective one of the one or more client devices associated with the first frequency band is associated with a media session, wherein the determination whether a respective one client device is associated with a media session is based upon characteristics of one or more packets being output to the respective one client device, wherein the characteristics are retrieved through a deep packet inspection of the one or more packets;
identify at least one client device from the one or more client devices associated with the first frequency band, wherein the at least one client device is identified based upon the determination whether the at least one client device is associated with a media session;
and
initiate a disassociation of the at least one identified client device from the first frequency band.

6 more elements

One or more non-transitory computer readable media having instructions operable to cause one or more processors to perform the operations comprising:

monitoring the status of one or more frequency bands;
determining that a condition exists for disassociating one or more client devices from a first frequency band in favor of steering the client device to an association with a second frequency band, wherein the condition is based upon the monitored status of the one or more frequency bands;
identifying one or more client devices associated with the first frequency band;
determining whether each respective one of the one or more client devices associated with the first frequency band is associated with a media session, wherein the determination whether a respective one client device is associated with a media session is based upon characteristics of one or more packets being output to the respective one client device, wherein the characteristics are retrieved through a deep packet inspection of the one or more packets;
identifying at least one client device from the one or more client devices associated with the first frequency band, wherein the at least one client device is identified based upon the determination whether the at least one client device is associated with a media session;
and
disassociating the at least one identified client device from the first frequency band.
