  • Patent number: 10271376
    Abstract: Delay in IMS call establishment and other time critical data transfers may be reduced by seeking alternative transmission methods for time critical data, when a transmission cannot be completed or the Radio Access Technology is otherwise unavailable. A Critical Service Manager (“CSM”) receives and evaluates priority information about a given data transfer. By evaluating this priority information, the CSM can identify priority data, or latency intolerant data, such as IMS calls or emergency calls. Where network rejects a connection request and issues a wait timer, the CSM may lower the retransmission count to hasten a permanent transmission failure. Upon a permanent transmission failure, the CSM can determine an alternative protocol for transmission of the priority data, such as transmitting data through circuit switch fallback, via Wi-Fi, or through another legacy RAT.

  • Patent number: 10148490
    Abstract: An online network device monitoring and recovery system generates, based at least in part on a schema that describes entities included in a network device, a software entity profile of entity object instances that represent the entities included in the network device, the entities including both hardware components and interfaces between the hardware components. The system registers the software entity profile to one or more proxies implemented on the network device. The system receives diagnostic information corresponding to a respective entity from the plurality of entities represented in the software entity profile registered to the one or more proxies. The system communicates diagnostic information for the respective entity, and a respective connective path through the entities for the respective entity based at least in part on the software entity profile.

  • Patent number: 10129878
    Abstract: Systems and methods for dynamically switching between frequency bands as a result of a detected condition that has the potential to degrade performance on the current band of operation. An access point having the capability to operate on multiple bands provides information necessary to form a communication link on a different band of operation, such as the channel of operation and any security credentials. Accordingly, a device that is associated with the access point on one frequency band may first receive the alternate band switching information and subsequently dynamically switch to a different band of operation using the alternate band information.

  • Patent number: 10129123
    Abstract: A measurement apparatus calculates a rate based on a time base of a second communications apparatus by dividing a total data amount arriving between two arbitrary response messages corresponding to transmission data, by a difference in transmission time information of the response messages. The measurement apparatus calculates a time conversion factor between a first communications apparatus and the second communications apparatus. The measurement apparatus calculates an arrival rate of the transmission data based on a time base of the first communications apparatus, by multiplying the calculated rate by the calculated time conversion factor.

  • Patent number: 10084684
    Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address. Each network device receiving the ELM may then propagate the ELM on a plurality of its ports to a plurality of downstream network devices based on the target address. In addition, each receiving network device returns an exploratory linktrace reply (ELR) for each of the plurality of ports, where each ELR is returned according to one or more mechanisms to mitigate stormed replies to the initiating network device.

  • Patent number: 10075862
    Abstract: Wireless access point devices having wireless networks operating in accordance with 802.11b/g 2.4 Ghz Wi-Fi can be affected by out-of-band interference caused by LTE small cell devices such as macrocells and femtocells. The wireless access points detect such interference devices using a flow processor to monitor the characteristics of data flows of devices connected to the wireless access point to determine whether they are LTE cells based on MAC address matching or the termination of a flow at a known mobile network operator gateway. When a cell is detected, the wireless access point scans for neighboring wireless networks of neighboring wireless access points which may also be affected by the interference generated by the LTE cell.

    Abstract: A network of physically linked elements includes at least a first switch, a second switch, and a third element. The third element is caused to transmit a data unit. A first timestamp and a second timestamp are obtained from the first and second switches, respectively. The first timestamp is associated with receipt of the transmitted data unit by the first switch and the second timestamp associated with receipt of the transmitted data unit by the second switch. The first timestamp and the second timestamp are compared. Based on the comparison, a determination is made that the first switch is physically located between the third element and the second switch.

  • Patent number: 10033733
    Abstract: Biometric markers are seen as a secure and convenient way to control an individual's access to systems. The data that comprise these access controls, however, can be spoofed by nefarious third parties. Therefore, systems and methods are provided that track metadata related to the usage of biometric markers as access control devices to improve the security of systems using biometric markers for access control and to improve the speed and efficiency for systems when re-granting access for an individual in the event that access was revoked or suspended. A bureau collects metadata related to the authentication of individuals via biometric markers and the activities of the individual and the systems accessed. These metadata are used by the bureau to alert affected parties of potential misuse of biometric data and to reduce the processing requirements, storage requirements, and number of communications to on-board or re-authenticate an individual.
