Techniques for performing optimized handovers of a client device between access points in wireless networks are provided. A first access point exchanges packets with a client device. The first access point receives a disassociation notice from the client device. In response to the disassociation notice, the first access point buffers one or more packets received for the client device in a first buffer. The first access point receives an indication from a controller to transmit the one or more packets in the first buffer to a second access point. In response to the indication, the first access point transmits the one or more packets in the first buffer to the second access point.

Handovers in wireless controller-based systems

Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.

Wireless dynamic file exchange

Opportunistic power grant, and specifically to providing opportunistic power grants to Access Points (APs) by an Automated Frequency Coordination (AFC) may be provided. An Access Point may be operating in a low power mode. The AP may connect to a STA and send a token to the STA, wherein the token includes a request for a STA location. The AP may receive the STA location in response. The AP may send the token and the STA location to an AFC. The AP may then receive instructions to operate in a standard power mode from the AFC. The AP may change operation to the standard power mode in response.

Opportunistic standard power grant by automated frequency coordination

In one embodiment, a device sends data traffic to a gateway of a backhaul mesh network via a first wireless access point of the backhaul mesh network. The device maintains, while associated with the first wireless access point, an association with a second wireless access point of the backhaul mesh network by sending a frame to the first wireless access point that is relayed by the first wireless access point to the second wireless access point. The device makes a determination that additional data traffic should be sent to the gateway of the backhaul mesh network via the second wireless access point. The device sends, based on the determination, the additional data traffic to the gateway of the backhaul mesh network via the second wireless access point.

Maintaining multiple wireless associations via an over-the-wire relay

Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.

Dynamic media access control addresses in a wireless network

Techniques are provided that rotate a device address used to identify a wireless client device on a wireless network. The wireless client device and at least one network infrastructure component identify a plurality of device addresses associated with the wireless client device. In some embodiments, the plurality of device addresses are generated via a corresponding plurality of invocations of a stateful random number generator, such as a cryptographically secure pseudorandom number generator.

Seamless device address rotation

Techniques to adaptively support/enable a wireless network feature for certain wireless client devices without hampering the performance or connectivity of wireless client devices which do not support that wireless network feature. An access point or wireless network controller adaptively enables a wireless network feature without advertising support for the wireless network feature in a wireless network-standard compliant manner to allow one or more wireless clients that support the wireless network feature to use the wireless network feature when associated to the access point while enabling association of one or more wireless clients that do not support the wireless network feature.

Adaptive wireless network feature support

A Radio Access Network (RAN) element provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The RAN element determines that the RAN element is connected to at least one gateway that provides public internet access, and broadcasts an internet indication. The RAN element determines that the UE has requested public internet access via the RAN element and provides the UE with public internet access.

Internet access indication in private LTE networks and neutral host networks

In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.

In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

Throughput and wireless channel interference mitigation for mobile systems

Systems, methods, and computer-readable media are provided for an efficient roaming management method using a single association identifier token for associating with different access points. In one aspect of the present disclosure, a network controller includes memory having computer-readable instructions stored therein and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive a request from an endpoint to connect to a first access point; generate association identification token (e.g., PMK and PMKID) for the endpoint to connect to the first access point; and distribute the association identification token to a second access point prior to the endpoint attempting to connect to the second access point, the association identification token being used by the second access point to validate a subsequent request by the endpoint to connect to the second access point.

Access point manager for roaming user products

A network management center includes a Dynamic Host Configuration Protocol (DHCP) server. The network management center obtains from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric. The network management center obtains from an edge node in the network fabric an Internet Protocol (IP) address request for the client device. The IP address request including a fabric domain identifier associated with the edge node. The network management center allocates an IP address for the client device based on the client information obtained from the identity server and the fabric domain identifier contained in the IP address request obtained from the edge node. The network management center provides to the edge node an Identifier Locator Addressing (ILA) address based on the IP address.
