Wireless Fidelity (Wi-Fi) Alliance (WFA) Wi-Fi quality of service (QoS) Management provides several way to manage QoS in a Wi-Fi network between access points and stations (such as client devices). For example, mirrored stream classification service (MSCS) enables station initiated negotiation of downlink QoS based on QoS mirroring, differentiated service code point (DSCP)-to-IEEE 802.11 user priority (UP) mapping assigns downlink and uplink QoS based on DSCP marking of internet protocol (IP) packets, either using a default mapping table, or using a specific mapping table configured using QoS map capability, stream classification service (SCS) enables a station initiated negotiation of downlink QoS based on explicit stream classifiers, and DSCP policy capability enables unsolicited and query-based configuration of uplink DSCP marking policies by access points on stations. The first two examples are initiated by a station, while the third example applies to a QoS mapping configuration assigned to a station and access point, and the fourth method is initiated by an access point.
For the fourth example, an access point is presumed to know what downstream QoS (for example, DSCP) to assign to certain traffic (for example, traffic sessions associated with specific applications) and to request a station make a similar upstream QoS assignment. The access point must know what type of traffic needs what QoS support. An application needing QoS for one or more associated traffic sessions and the associated QoS requirements for traffic associated with the application can be determined via a user assignment and can be remotely configured (for example, using a cloud management system). However in doing so, the user is burdened with individual application and application QoS determinations. Additionally, application assignment may also be restricted to tuple information (IP source/destination addresses, MAC source/destination addresses, and transport protocol type) which may not address all QoS traffic needs. Thus there is a need for improved Wi-Fi QoS Management that does not burden a user.
According to aspects of the present invention, an access point device with deep packet inspection (DPI) support (for example, a gateway device) can provide improved Wi-Fi QoS Management and upstream (US) wide area network (WAN) QoS without burdening a user with excessive configuration requirements. DPI allows for identification of traffic associated with an application as well as one or more device categories. The access point device can be remotely (or locally) configured with a DPI application and/or one or more device categories that need added QoS and the QoS assignments for these one or more device categories. The access point device can utilize DPI to detect traffic associated with a chosen or selected application and/or device category - this may occur within one or more packets at the start of an application and/or traffic session of a network device. The access point device can then assign the appropriate QoS whether downstream or upstream to the traffic depending on the chosen or selected application and/or one or more device categories. In this way, high priority traffic receives a sufficient QoS to support the needs of the corresponding application, device, or both.
An aspect of the present disclosure is drawn to an access point device to provide quality of service (QoS) prioritization using deep packet inspection (DPI). The access point device comprises a memory storing one or more computer-readable instructions, and a processor coupled to the memory. The processor is configured to execute the one or more computer-readable instructions to cause the access point device to receive one or more packets from a station, inspect the one or more packets for QoS information using DPI, compare the QoS information to one or more DPI application categories, one or more DPI device categories, or both, determine a QoS policy from one or more QoS policies based on the comparison, and assign the QoS policy to traffic associated with the session.
In an aspect of the present disclosure, the processor is further configured to execute the one or more computer-readable instructions to further cause the access point device to receive any of the one or more DPI application categories, the one or more DPI device categories, one or more QoS policies, or any combination thereof from a network resource.
In an aspect of the present disclosure, the QoS policy is a wireless fidelity (Wi-Fi) QoS Management differentiated services code point (DSCP) policy.

In one or more embodiments, a station 140 (or wireless device) can be any type of a device that connects to an access point device 110 and is capable of or configured to send and/or receive one or more packets (also referred to generally as traffic), for example, any of a handheld computing device, a personal computer (such as a desktop, laptop, etc.), an electronic tablet, a mobile phone, a smart phone, an Internet-of-Things (IoT) device (such as smart assistant, iControl devices, portable music players with smart capabilities capable of connecting to the Internet, cellular networks, and interconnecting with other devices via Wi-Fi and Bluetooth (BT)), any other wireless electronic device, or any combination thereof. An electronic device 140 can be connected to an access point device 110 via a connection 105.
The access point device 110 can be an electronic device that supports DPI for use with providing Wi-Fi QoS Management. The access point device 110 can comprise an access point and/or a hardware electronic device that can be a combination modem and gateway that combines the functions of a modem (for example, a cable modem, DSL modem, passive optical network (PON) optical network terminal (ONT), and/or Fixed Wireless Access 5G modem), an access point (AP), and/or a router for providing content, data or information received from one or more stations 140 to a subscriber network 130. An access point device 110 can be referred to as a residential gateway, a home network gateway, or a wireless access point. The access point device 110 can comprise a DPI management device 112, a Wi-Fi QoS Management controller, and information associated with DPI and/or Wi-Fi QoS Management (for example, any of one or more DPI application categories 170, one or more DPI device categories 160, and one or more QoS policies 150, or any combination thereof) stored in a memory 200 as discussed with reference to
The DPI management device 112 can comprise hardware, software, or both for performing DPI of one or more packets, such as traffic, received by the access point device 110, for example, the DPI management device 112 can be any of an engine, a controller, any other software, any other hardware, or any combination thereof. The DPI management device 112 can inspect one or more packets received from a station 140, a subscriber network 130, or both and detect traffic associated with one or more application categories 170,one or more device categories 160, or both so as to identify an application, a station 140 or both for QoS management.
The Wi-Fi QoS Management controller 114 can comprise hardware, software, or both for managing the QoS of traffic received by the access point device 110. For example, the Wi-Fi QoS Management controller 114 can assign an appropriate QoS whether downstream or upstream to the traffic inspected by the DPI management device 112 and identified as associated with an application 142, a station 140, or both depending on a QoS policy 150 associated with or that corresponds to the identified application 142, the identified station 140, or both. In this way, high priority traffic receives a sufficient QoS to support the needs of the identified application, the identified station 140, or both based on an associated QoS policy 150.
The DPI application categories 170 can comprise any of a gaming application, a video streaming application, a security or monitoring application, a storage system application, a video conference application, any other application associated with an electronic device 140, or any combination thereof. For example, an application 142 can be associated with one or more DPI application categories 170. Each of the one or more DPI device categories 160 can be associated with at least one of the one or more QoS policies 150. The one or more DPI device categories 160 can comprise any of a gaming system, a video streaming system, a video conference system, a smart television, a set-top box, a security alarm or detection system, an electronic storage system, any other type of system and/or device that connects to the network 100 and/or the access point device 110, or any combination thereof. For example, a station 140 can be associated with one or more DPI device categories 160. Each of the one or more DPI device categories 160 can be associated with at least one of the one or more QoS policies 150. The one or more QoS policies 150 can comprise information to facilitate classification of one or more packets, such as any of a DSCP value, a priority value, any other prioritization information, or any combination thereof so as to indicate a priority for QoS. A QoS policy can indicate any of an upstream QoS priority for upstream station traffic (a QoS priority for traffic from the station 140 to the access point device 110), downstream station QoS priority for downstream station traffic (a QoS priority for traffic from the access point device 110 to the station 140), an upstream access point QoS priority for upstream access point traffic (a QoS priority for traffic from the access point device 110 to the network, such as to any of a subscriber network 130, a WAN 125, a network resource 120, or any combination thereof), or any combination thereof. For example, a QoS policy 150 can comprise a DSCP value that indicates a DSCP to application category assignment (for a subset of application categories that need high prioritization). As an example, gaming can be an application category and a gaming application with expedited forwarding (EF) can be assigned a DSCP of 46 and video streaming with real-time interactive (CS4) can be assigned a DSCP of 32 for a given session where DPI detected the respective application category. The session identification resulting from the DPI can be a tuple of source/destination IP address, source/destination port, and protocol, a source port, or destination port. The QoS policy 150 can comprise an IEEE 802.1Q (Dot 1Q) priority code point (PCP) (p-bit) to application category assignment. For example, p-bit values of 5 and 4 could be added for PON WAN egress traffic. Similarly, a QoS policy 150 can apply to a device category needing prioritization.
A subscriber network 130 can be communicatively coupled to the access point device 110 via a connection 109. For example, the access point device 110 can route to the subscriber network 130 one or more packets (or traffic) assigned a QoS based on an associated QoS policy 150 as determined by the Wi-Fi QoS Management controller 114 based on DPI performed by the DPI management device 112. The subscriber network 130 can, for example, be located at a head end of a multiple system operator (MSO). The subscriber network 130 can connect the access point device 110 to a network resource 120 via a connection 107 between the subscriber network 130 and a WAN 125 and via a connection 11 between the WAN 125 and the network resource 120. The network resource can configure the access point device for using DPI, for example, by providing and/or updating one or more DPI application categories 170, one or more DPI device categories 160, one or more QoS policies 150.
The memory 220 can store information within the hardware configuration 200, such as any of the one or more DPI application categories 170, the one or more DPI device categories 160, the one or more QoS policies 150, or any combination thereof are stored in the data storage unit 230. In one implementation, the memory 220 can be a non-transitory computer-readable medium that stores one or more computer-readable instructions, such as software 260, that when executed by a processor 210 cause the network device to perform one or more operations according to one or more aspects of the present disclosure. For example, the Wi-Fi QoS Management controller 114, the DPI management device 112, or both can comprise any of a processor 210, a memory 220, a software 260, any other hardware element, any other one or more computer-readable instructions, or any combination thereof. In one implementation, the memory 220 can be a volatile memory unit. In another implementation, the memory 220 can be a non-volatile memory unit. In one or more embodiments, the storage device 230 can be capable of providing mass storage for the hardware configuration 200. In one implementation, the data storage unit 230 can be a non-transitory computer-readable medium. In various different implementations, the data storage unit 230 can, for example, include a hard disk device, an optical disk device, flash memory or some other large capacity storage device. In other implementations, the data storage unit 230 can be a device external to the hardware configuration 200.
The I/O device 240 provides I/O operations for the hardware configuration 200. In one implementation, the I/O device 240 can include one or more of a network interface device (for example, an Ethernet card), a serial communication device (for example, an RS-232 port), one or more universal serial bus (USB) interfaces (for example, a USB 2.0 port), one or more wireless interface devices (for example, an 802.11 card) for outputting video, voice, and/or data services to a station 140 of
At 302, the access point device 110 determines that DPI is supported. At 304, DPI management device 112 of the access point device 110, receives configuration information from a user or an operator service, for example, as provided by any of the subscriber network 130, the network resource 120, a user interface (such as any of a web portal, a command line interface (CLI), any other user interface, or any combination thereof), or any combination thereof. The configuration information is used by the DPI management device 112 to configure any of one or more DPI application (app) categories 170, one or more DPI device (dev) categories 160, or any combination thereof. At 306, the Wi-Fi QoS Management controller 114 configures the one or more QoS policies 150 based on the configuration information. For example, any or each of the one or more DPI device categories 160, the one or more DPI application categories 170, or both can be associated with a QoS policy 150. In one or more embodiments, a default configuration can be used for the one or more DPI device categories 160, the one or more DPI application categories 170, and the associated one or more QoS policies 150. In one or more embodiments, processor 210 can execute one or more computer-readable instructions stored in a memory 220 to configure any of the one or more DPI application categories 170, the one or more DPI device categories 160, the one or more QoS policies 150, or any combination thereof.
At 308, the DPI management device 112 runs DPI to identify a session associated with a DPI application category 170, a DPI device category 160, or both. For example, the access point device 110 can receive one or more packets associated with a session of the station 140. The DPI management device 112 can parse from or otherwise inspect the one or more packets (such as an IP header) for information associated with a QoS priority and compare the information (for example, a signature) to a DPI device category 160, a DPI application category 170, or both. If the comparison results in a match (for example, the information matches or corresponds to a DPI device category 160, a DPI application category 170, or both), the session is identified as a target session. At 310, the DPI management device 112 determines if a target session was identified. If a target session was not identified, then the process continues to 308. If a target session is identified, the process continues to step 312.
At 312, the Wi-Fi QoS Management controller 114 sets an associated downstream (DS) QoS, for example, a DSCP, for the target session identified in step 310, for example, a downstream session to wireless local area network (WLAN) interface. Setting a DS QoS for a target session associated with a high priority DPI application category 170, a DPI device category 160, or both results in an appropriate Wi-Fi multi-media (WMM) QoS prioritization. At 314, the Wi-Fi QoS Management controller 114 sets an associated upstream (US) QoS, for example, a DSCP, for the target session identified in step 310, for example, an upstream session to WAN interface.
At 316, the Wi-Fi QoS Management controller 114 determines if the station 140 associated with the target session supports Wi-Fi QoS Management. If not supported, the process continues to 308. If supported, the process continues to 318. At 318, the Wi-Fi QoS Management controller 114 issues a Wi-Fi QoS Management (Mgt) request, for example, a DSCP policy request, to a station 140 for an upstream WAN QoS.
The WAN interface 402 of the access point device 110 receives a network DS session 410. The network DS session 410 can be prioritized by an operator. The access point device 110 can determine that a session is associated with a QoS policy 150 based on DPI of one or more packets associated with the session, for example, information associated with the one or more packets match a DPI device category 160 and/or a DPI application category 170, such that the session is identified as a target session. Traffic or packets associated with a DS session 430 are prioritized for sending to the WLAN interface 406 by the access point device 110 based on the QoS policy 150 associated with the target session. The station 140 can also be configured by the access point device 110 to prioritize an US session 440 associated with the target session for sending associated traffic or packets from the WLAN interface 406 to the WLAN interface 404. Similarly, the access point device 110 can prioritize an US session 420 for sending traffic or packets associated with the target session to a WLAN 125.
The processor 210 executes one or more computer-readable instructions, stored in a non-transitory computer-readable memory, for example, a memory 220 of an access point device 110, that when executed by the processor 210 perform and/or cause the access point device 110 to perform one or more of the operations of steps 602-616. In one or more embodiments, the one or more computer-readable instructions may be one or more software applications. While the steps 602-616 are presented in a certain order, the present disclosure contemplates that any one or more steps can be performed simultaneously, substantially simultaneously, repeatedly, in any order or not at all (omitted).
Prior or during operation or functioning of the access point device 110 to perform any of the steps 602-616, the access point device 110 can receive any of one of the one or more DPI application categories 170, the one or more DPI device categories 160, the one or more QoS policies 150, or any combination thereof, for example, from a network resource 120, a user, a subscriber network 130, or any combination thereof. In one or more embodiments, the access point device 110 is within an EasyMesh network, such as an EasyMesh R4 or later network, and the station is an extender access point device. At step 602, the access point device 110 receives one or more packets from a station 140. The one or more packets can be associated with a session and can require an enhanced QoS such that the one or more packets and any associated traffic (one or more other packets sent to and/or from the station 140) should be given a high priority as compared to other traffic.
At step 604, the access point device 110 inspects the one or more packets for QoS information using DPI. The QoS information can be any information that allows the access point device 110 to match the QoS information with a QoS policy 150, such as information indicative of an application (such as an application 142), a device (such as a station 140), or both.
At step 606, the access point device 110 compares the QoS information to one or more DPI application categories 170, one or more DPI device categories 160, or both. The comparison can provide or determine whether the QoS information matches or otherwise corresponds to any of the one or more DPI application categories 170, any of the one or more DPI device categories 160, or both.
At step 608, the access point device 110 determines a QoS policy 150 based on the comparison from step 606. For example, the access point device 110 can determine that the QoS information obtained from DPI of the one or more packets indicates that the one or more packets of a session are associated with an application, a device, or both that requires high priority based on a corresponding QoS policy 150. As an example, the access point device 110 can compare the QoS information to one or more of the DPI application categories 170. The comparison can indicate that the QoS information identifies a particular application that matches or corresponds to at least one of the DPI application categories 170. The access point device 110 can determine that the matched or corresponding DPI application category 170 is associated with a QoS policy 150. The QoS policy 150 can indicate a priority to be used for a traffic of the session directed to the particular application identified by the QoS information. In one or more embodiments, the QoS policy 150 is a Wi-Fi QoS Management DSCP policy.
At step 610, the access point device 110 can assign the QoS policy to a traffic associated with the session where the traffic is associated with a particular application, a particular device, or both as indicated by the comparison of step 606 based on the QoS information. Assigning the QoS policy in step 610 can comprise at least one of the steps 612, 614, and 616 such that any of steps 612, 614, 616, or any combination thereof can be performed by the access point device 110. In this way, a session (and the one or more packets or traffic associated with the session) is given an appropriate or required priority. For example, at step 612, the access point device 110 sends a request to the station 140 to assign an upstream station QoS priority to upstream station traffic of a session associated with the one or more packets based on the QoS policy. Similarly, at step 614, the access point device 110 assigns a downstream station QoS priority to downstream statin traffic of the session associated with the one or more packets based on the QoS policy. Similarly, at step 616, the access point device 110 assigns an upstream access point QoS priority to upstream access point traffic of the session associated with the one or more packets based on the QoS policy. In one or more embodiments, the upstream station QoS priority provides a Wi-Fi multi-media (WMM) upstream QoS prioritization. In one or more embodiments, the downstream QoS priority provides a WMM downstream station QoS prioritization.
