Abstract: According to one embodiment, a network device is configured to measure a quality of service associated with a real-time streaming packet received at a first transmission rate. The network device gathers metrics to a call quality based on the quality of service, wherein the metrics are specific to a wireless call quality, and adjusts the first transmission rate to a second transmission rate based on the metrics. Herein, the second transmission rate replaces the first transmission rate to balance between a transmission delay and reliability of the real-time streaming packet.

Abstract: A non-transitory computer readable medium includes instructions which, when executed by one or more hardware processors, causes performance of operations. The operations include receiving, by a network device from a first user device, a first message addressed to a second user device and identifying a first user role associated with the first user device and a second user role associated with the second user device. The operations further include determining whether a set of predefined user role relationships authorizes a communication between user devices having the first user role and user devices having the second user role. In response to determining that the set of predefined user role relationships do not authorize the communication between user devices having the first user role and user devices having the second user role, the operations refrain forwarding the first message from the first user device to the second user device.

Abstract: The present disclosure discloses a method and network device for intelligent handling of voice calls from mobile voice client devices. In some embodiments, the network device detects that a load, corresponding to a plurality of client devices associated with an access point, exceeds a particular threshold value. In some embodiments, the network device detects that a call quality for a current ongoing call, corresponding to a first client device associated with an access point, is below a first threshold value. In response, the network device selects a particular client device, of the plurality of client devices associated with the access point, for disassociation with the access point. The network device then causes the particular client device to disassociate with the access point.

Abstract: The present disclosure discloses a network device and/or method for determination of leveled security key holders for a wireless client in a wireless network. The network device detects a roaming or connection pattern of one or more wireless clients in the wireless network based on requests received from the wireless clients. Furthermore, the network device determines one or more selecting rules for selecting an appropriate key holder for the wireless client among a plurality of network devices. Next, the network device prioritizes the one or more selecting rules, and selects the appropriate key holder based on the determined rules and their corresponding prioritization. Through selection of appropriate key holders, the disclosed method provides for better load balancing among possible leveled key holders, and shortens the latencies experienced by wireless clients during fast basic service set transition.

Abstract: The present disclosure discloses a network device and/or method for providing data link layer (L2) and network layer (L3) mobility using level security keys. A first network device acting as a first level security key holder in a first network receives a first level security key holder identifier corresponding to a second network device in a second network. The first level security key holder identifier is originated from a client that roams from the second network to the first network. Moreover, the first network and the second network belong to a single roaming domain. Also, the network device transmits the first level security key holder identifier to the second network device and requests for corresponding first level security key. The network device then derives a second level security key and transmits a second level security key identifier the second level key holder in the first network.

Abstract: The present disclosure discloses a network device and/or method for pro-active propagation of second level security keys (e.g., PMK-R1) to a wireless client's neighboring wireless network devices. The wireless network device derives a first level security key (e.g., PMK-R0) and one or more second level security keys (e.g., PMK-R1) during an initial mobility domain association initiated by the wireless client. Then, the wireless network device determines a subset of wireless network devices in the neighborhood of the wireless client to which it may pro-actively propagate one or more second level security keys corresponding to the wireless client prior to the wireless client initiating a Fast BSS Transition (FT) to any network device in the subset. This would reduce the duration of time that data connectivity is lost between the wireless client and the network during the FT process.

Abstract: Transitioning voice clients among network resources. A network monitor using IEEE 802.11e QBSS Load IE elements monitors the load on one or more wireless access points. When the load on an access point, as reported in the QBSS Load Element IE exceeds a predetermined threshold, the network monitor sends a message to that AP which causes the AP to send BSS Transition Management Request frames to all connected voice clients which are currently idle. The information passed to the AP and then to the client may include one or more neighboring APs with capacity.
