Abstract: Described herein are devices, systems, methods, and processes for improving retransmissions in wireless communication networks by distinguishing between temporal interference and longer-term radio frequency (RF) condition issues. The fact that the access point (AP) does not usually move may be leveraged, and a machine learning process can be utilized to learn and adapt to the RF conditions in the cell. The AP records various parameters for each frame received from client devices and uses this data to build a pairwise temporal matrix. Machine learning models are trained using these parameters, enabling the AP to compute the likely efficient set of modulation and coding schemes (MCSs) at each static position and along moving positions. The AP can then adapt its MCS accordingly for the downlink traffic and provide the client device with recommended MCSs for upcoming uplink transmissions. Accordingly, the retry count at the client devices can be reduced.

Abstract: A trigger to enable data traffic replication in a wireless network may be provided. A data packet comprising a Differentiated Service Code Point (DSCP) field in a header may be received. A determination may be made that the data packet comprises a candidate traffic for bi-casting. In response to determining that the data packet comprises the candidate traffic for bi-casting, a flag may be set in the DSCP field in the header of the data packet. The flag triggers bi-casting of the data packet. The data packet may be sent to a destination device.

Abstract: A first access point of a wireless network minimizes Media Access Control (MAC) address collisions in the wireless network. The first access point receives an association request from a first wireless device. The association request identifies a first MAC address of the first wireless device. The first access point determines whether a second wireless device is associated with the wireless network using the first MAC address. Responsive to a determination that the second wireless device is associated with a second access point of the wireless network, the first access point obtains a virtual MAC address for the first wireless device. The first access point translates between the first MAC address and the virtual MAC address for network traffic of the first wireless device.

Abstract: Stateful roaming techniques are provided for use in a wireless network. In one embodiment, a method is provided that includes: obtaining flow information descriptive of one or more traffic flows associated with a wireless client device that is associated to a current access point in a wireless network; storing state data representing the flow information for flows associated with the wireless client device together with a traffic descriptor for each flow; determining that the wireless client device is seeking to roam from the current access point to a new access point; and sending the state data for the wireless client device to the new access point to enable the new access point to apply a policy based on the state data before the wireless client device completes its roam to the new access point.

Abstract: Described herein are devices, systems, methods, and processes for energy-efficient routing in a cloud environment. The system includes a load balancer that distributes incoming traffic across multiple application instances hosted within different availability zones (AZs) based on a preference for sustainable energy sources as communicated by a client device. The client device communicates its preference for sustainable energy sources through a sustainability flag included in a service request. The load balancer steers the service request to the suitable resource based on the sustainability flag. In subsequent interactions, the client device can send a service request with a configuration, such as a sticky cookie. The configuration may allow the load balancer to consistently direct requests from the same client device to the same resource. Accordingly, the embodiments enable energy-efficient routing, client preference for sustainable energy, and consistent service, and contribute to environmental protection.

Abstract: In one embodiment, a device obtains telemetry data indicative of channel usage by a plurality of Bluetooth Low Energy (BLE) tags. The device also obtains tag characteristic data indicative of one or more characteristics of the BLE tags. The device determines that usage of a particular channel by the BLE tags exceeds a predefined threshold, based on the obtained telemetry data. The device selects a subset of the plurality of BLE tags, based on their one or more characteristics indicated by the obtained tag characteristic data. The device instructs, for each of the selected subset of BLE tags, the selected BLE tag to increase an interval of time between BLE advertisements sent by the selected BLE tag.

Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address, the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first MAC address.
