Abstract: The use of device context in applying security policies is provided by receiving a Domain Name Service (DNS) query for a network resource from a user device (UD) at a DNS analysis server, the DNS query including a functional label describing a context of the UD; analyzing the DNS query to determine whether the UD is permitted to access the network resource based on the functional label; and in response to the functional label indicating that the UD is not permitted to access the network resource, transmitting a block page to the UD. The functional label can be added to the DNS query by a Mobile Device Management application on the UD, a router associated with the UD, or an enterprise server. Contexts for previously blocked DNS queries can be aggregated to identify UDs sharing at least one value with the previously blocked DNS queries as security compromised devices.

Abstract: The present disclosure discloses a system including a controller and a plurality of radio heads communicatively coupled to the controller. The controller transmits a synchronization signal to each of the radio heads to synchronize the local clocks in the radio heads to a master clock in the controller. The controller also transmits packets to the radio heads. Each of the radio heads includes a deframer. For a radio head, upon detecting that a received packet from the controller includes an error, the deframer alters the received packet to maintain the synchronization between the controller and the radio head and transmits data contained within the altered packet.

Abstract: Techniques for improved wireless ranging are provided. A first communication from a first client device is received at a first network device. A predefined minimum distance is determined for the first access point, where the predefined minimum distance corresponds to a distance at which the vertical location of the first network device causes time of flight ranging techniques to result in inaccurate location estimations. A first distance of the first client device from the first network device is estimated. Upon determining that the first distance of the first client device is below the predefined minimum distance, ToF ranging requests from the first client device are declined.

The controller may then create a transmission schedule for transmissions between the plurality of APs in the mesh network based on the assigned OBSS colors.

Abstract: Exemplified systems and methods facilitate multicasting latency optimization operations for router, switches, and other network devices, for routed Layer-3 multicast packets to provide even distribution latency and/or selective prioritized distribution of latency among multicast destinations. A list of network destinations for serially-replicated packets is traversed in different sequences from one packet to the next, to provide delay fairness among the listed destinations. The list of network destinations are mapped to physical network ports, virtual ports, or logical ports of the router, switches, or other network devices and, thus, the different sequences are also traversed from these physical network ports, virtual ports, or logical ports. The exemplified systems and methods facilitates the management of traffic that is particularly beneficial in in a data center.

A second copy of the packet descriptor is queued in a second scheduler associated based on processing the second copy of the packet descriptor with the second processing pipeline. Upon determining that the first policy is currently active on the network device, the first copy of the packet descriptor is dequeued from the first scheduler.

Abstract: A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.
