  • Patent number: 8799511
    Abstract: Techniques are described for synchronizing state information between a plurality of control units. A router, for example, is described that includes a primary control unit and a standby control unit. The primary control unit maintains router resources to ensure operation of the router. To ensure operation, the primary control unit receives state information from the router resources and maintains the state information for consumers, i.e. router resources that require or “consume” state information. Prior to updating the consumers with the state information, the primary control unit synchronizes the state information with the standby control unit. In the event the primary control unit fails, the standby control unit assumes control of the router resources. Upon assuming control, the standby control unit resumes updating the consumers with state information without having to “relearn” state information, e.g., by way of power cycling the router resources to a known state.

  • Patent number: 8745179
    Abstract: A system that enables automatic version provisioning in heterogeneous application oriented network (AON) architectures is provided. Generally, the specification enables appropriate version configurations to be selected at runtime as needed in an AON environment. More particularly, the subject specification describes the ability of a device (e.g., AON node) to perform and/or select a self-configuration operation based upon the environment and the runtime operation. To facilitate message-based runtime instantiation of the appropriate configuration, the system enables network applicable configurations to be pushed to each of the nodes in the AON architecture.

  • Publication number: 20140090113
    Abstract: An Engineered Transgene Integration Platform (ETIP) is described that can be inserted randomly or at targeted locations in plant genomes to facilitate rapid selection and detection of a GOI that is perfectly targeted (both the 5? and 3? ends) at the ETIP genomic location. One element in the subject disclosure is the introduction of specific double stranded breaks within the ETIP. In some embodiments, an ETIP is described using zinc finger nuclease binding sites, but may utilize other targeting technologies such as meganucleases, CRISPRs, TALs, or leucine zippers. Also described are compositions of, and methods for producing, transgenic plants wherein the donor or payload DNA expresses one or more products of an exogenous nucleic acid sequence (e.g. protein or RNA) that has been stably-integrated into an ETIP in a plant cell. In embodiments, the ETIP facilitates testing of gene candidates and plant expression vectors from ideation through Development phases.
