  • Patent number: 9553720
    Abstract: An application that consumes key management information (e.g., keys and certificates) through a conventional keystore API is configured to recognize a new keystore type. In addition, the services of that API are pointed to a management server component associated with a key management protocol (e.g., KMIP), and a client component of the key management protocol is instantiated as a “semi-remote” keystore in association with the application. Once configured to use the new keystore type, the consuming application uses the keystore API in a conventional manner, but calls to the new keystore type are directed to the KMIP client. The client intercepts these calls and then interacts with the KMIP server on behalf of the consuming application, and without the application being aware of the interaction over the KMIP client-server API. This approach enables the consuming application to take advantage of the full benefits provided by the key management protocol transparently.

  • Patent number: 9553734
    Abstract: A switch (110R.3) uses a forwarding database (140F) to forward multicast packets. The switch participates in a multicast protocol (e.g. PIM) with other switches, and also uses a snooping database (e.g. for IGMP snooping) to learn about local group members, i.e. members for which the router serves as a local multicast router (e.g. the local members do not participate in the multicast protocol). When the switch learns of a local member of a multicast group, the switch updates the snooping database but may or may not install the snooping information in the forwarding database. Thus, the forwarding database is not necessarily provisioned for locally sourced data packets addressed to the group until receipt of a locally sourced data packet addressed to the group. If no such packets are received, the forwarding database is not provisioned for such packets, and therefore its size is reduced. Other features are also provided.

  • Patent number: 9553751
    Abstract: A demodulation device for demodulating a base signal from a composite signal, which is composed of a carrier wave and a sensor modulation signal of the base signal. The demodulation device determines a difference between the composite signal of a former-half period and the composite signal of a latter-half period to be a pre-correction base signal. The former-half period is a one-half period of a sampling period starting at one of a local maximum and a local minimum of the carrier wave. The latter-half period follows the former-half period. The demodulation device determines a reference level from the composite signal and determines a signal level of a post-correction base signal based on a ratio between a signal level of the pre-correction base signal and the reference level.

The frequency offset estimation may need to be performed even without having time synchronization with a base station. In case of cellular systems multiple base stations may be using the same RF channel to transmit their signals. The signals from different base stations may be superimposed at the receiver of the client terminal. A method and apparatus are disclosed for frequency offset estimation in presence of the signals from multiple base stations and with unknown timing of the base station.

  • Patent number: 9553754
    Abstract: A method and apparatus for reducing distortion of satellite signals modulated using amplitude phase shift keying (APSK) are disclosed. A receiver such as a user terminal receives, from a satellite, a signal including APSK-modulated symbols mapped to a constellation including a plurality of points arranged in an inner circle and in an outer circle; determines, based on the received APSK-modulated symbols, a ratio between a radius of the inner circle of the constellation and a radius of the outer circle of the constellation; generates a correction signal based, at least in part, on a comparison between the determined ratio and a reference ratio; compensates for distortion of the received signal based, at least in part, on the correction signal; mixes the correction signal with the received signal to generate a distortion-compensated signal; and de-modulates the distortion-compensated signal to recover data transmitted from the satellite.

  • Patent number: 9553756
    Abstract: Methods and systems for inter-destination synchronization in first and second receivers for content parts associated with a play-out timeline are disclosed. First timing information comprising first content part identifiers and associated first clock times may be determined, where the first receiver may receive a first content part identifier comprising first fingerprints for identifying a first content part in a first media stream. Second timing information comprising second content part identifiers and associated second clock times may be determined, where the second receiver may receive a second content part identifier identifying a second content part in a second media stream based on the first and second timing information. A timing difference in processing a content part in the first and second media streams may be calculated. Based on the timing difference, synchronization information for inter destination synchronization between said first and second streams may be generated.

  • Patent number: 9553757
    Abstract: Approaches are described for allowing an access control policy to specify that a substitute operation be executed when a request for access matches certain conditions specified in the access control policy (e.g., when the identity of the requestor matches a specified identity in the policy). For example, the access control may specify that a substitute result should be provided to a requestor in response to a request for access or a substitute request should be executed instead of executing the received request and the results of the substitute request should be provided to the requestor in response to the request. The substitute result or the result of the substitute request may appear to the requestor as though their original request for access succeeded but the content of the result may be different than what would have been generated if the access control policy allowed the request to proceed.

  • Patent number: 9553760
    Abstract: A method, device, and system for dual-uplink tangent ring convergence, where ports on a network device are classified into conjugate ports and non-conjugate ports. When receiving an entry update packet from a first port or perceiving a state change of a first port, when it is determined that the first port of the network device is a conjugate port, the network device clears a media access control (MAC) entry and an Address Resolution Protocol (ARP) entry that use the first port as an outbound interface and clears all MAC entries that use a non-conjugate port as an outbound interface, in a MAC table and an ARP table of the network device. In this way, traffic interruption can be avoided, wherein a failure of one dual-uplink tangent ring does not cause an entry of one or more other normal dual-uplink tangent rings to be cleared/updated.

  • Patent number: 9553762
    Abstract: Systems and methods are provided herein for providing an NoC including a configurable array of nodes, where a node of the configurable array of nodes operates in a default operating mode until a replacement operating mode is triggered. For example, when an NoC is unconfigured, a latch bank may be initialized to “clear,” such that no routing decisions are stored. This may enable a default operating mode where routing logic updates the latches' values as needed to implement required routing behavior in a dynamic fashion until configuration is performed.
