According to an example, an application initiating a communication session may be identified via a mapping of the application information with a pattern of interest included in a DNS server response corresponding to the application. Information regarding the communication session may be obtained and a determination may be made as to whether the communication session includes media data. If the communication session includes media data, control of the application and the communication session may be enabled via an interface.

The present disclosure discloses a system and a method for displaying mobile trails for mobile client devices. Specifically, a network device obtains a plurality of performance measurements and a corresponding plurality of physical locations for a client device over a period of time. Then the network device generates a plurality of visual representations for the client device over the period of time, each visual representation representing a respective performance measurement and a respective physical location at a respective time during the period of time. Moreover, the network device can display, store, and/or transmit a map of a physical environment with the plurality of visual representations.

System and method for displaying mobility trails for mobile clients

Described herein are systems, devices, techniques and products for operating network devices, such as wireless access points, in a network environment. For example, wireless client devices may have resources reserved for their use by a network device if the wireless client device is categorized for such resource reservation, such as if the wireless client device is categorized as more important than other wireless client devices. Such categorization may be indicated by a context associated with the wireless client device, including belonging to or being associated with an important user or being used for an important purpose, such as emergency purposes, prescheduled purposes or involving multiple users. Reservation of wireless resources for wireless client devices may be performed to ensure an important user or device is provided with adequate resources to place a voice or video call, for example.

Examples relate to managing network traffic. In one example, a computing device may: receive voice network traffic from each of a plurality of voice clients; enqueue the received voice network traffic into a voice Wi-Fi Multimedia (WMM) queue; determine a measure of WMM queue utilization based on data queued in the voice WMM queue; determine a measure of radio congestion for a surrounding area; and determine, based on the measure of WMM queue utilization and the measure of radio congestion, to: stop prioritization of newly received voice traffic from new voice clients, or transition at least one of the plurality of voice clients to a neighboring computing device.

Specifically, a network device obtains a plurality of performance measurements and a corresponding plurality of physical locations for a client device over a period of time. Then the network device generates a plurality of visual representations for the client device over the period of time, each visual representation representing a respective performance measurement and a respective physical location at a respective time during the period of lime. Moreover, the network device can display, store, and/or transmit a map of a physical environment with the plurality of visual representations.

System and method for providing context-based anticipatory dynamic resource reservation

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.

Intelligent handling of voice calls from mobile voice client devices

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.

Communication model based on user role

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.

Voice call handover

The present disclosure discloses a system and method for determining deterioration in call quality between one or more wireless end-users based on codec characteristics. Specifically, a network device determines a codec associated with a call between two client devices. Then, the network device determines a transmission rate based on the codec. Moreover, the network device estimates a number of packets to be received by an access point that a first client device is associated with based on the transmission rate, and compares the estimated number of packets to an actual number of packets received by the access point. If a difference between the estimated number and the actual number of packets exceeds a threshold, the network device diagnoses that a poor call quality associated with the call is due to either the first client device or network connectivity between the first client device and the access point.

System and method for determining deterioration in call quality between one or more wireless end-users based on codec characteristics

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.

System and method for dynamic rate adaptation based on real-time call quality metrics

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.
