  • Patent number: 10152524
    Abstract: Security on data storage and transport are important concerns on cloud computing. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. In short, the WF muxed data storage solution enhances data security and data redundancy by, respectively, creating a new dimension to existing security/privacy methods and significantly reducing the storage space needed for data redundancy.

  • Patent number: 10120873
    Abstract: Presented is a multi-channel data process to utilize wavefront multiplexing for data storage and data stream transport with redundancy on cloud or in a distribution network. This processing features additional applications for multi-media recording and data communications via transponding platforms including satellites, unmanned air vehicles (UAVs), or others for better survivability and faster accessing. Multiple concurrent data streams are pre-processed by a wavefront multiplexer into multiple sub-channels or wavefront components, where signals from respective data streams are replicated into sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wave-front”, which are also linked by various spatially independent wavefronts. Additionally, probing data streams are embedded and linked via some of the independent wavefronts. Aggregated data streams in sub-channels are unique linear combinations of all input data streams.

    Abstract: A virtual converged cable access platform (CCAP) system and method for hybrid fiber CATV (HFC) cable networks. The system uses a new type of digital optical fiber node configured to receive optical fiber data packets, and reconstitute the optical data packets into RF waveforms suitable for injection into the system's CATV cable. The system replaces the legacy HFC head end with a simplified “virtual head end”. The system's virtual head end operates using a new type of virtual CCAP controller and virtual CCAP software that in turn controls high performance edge routers. Much of the intelligence of running the HFC cable system is managed by the controller software, while the edge router manages the interface between the CATV portion of the system and outside networks. The system can handle even legacy CATV RF signals by appropriate conversion operations, while reducing power and space needs, and improving operational flexibility.

  • Patent number: 9755728
    Abstract: Methods and systems are provided for guard band detection and/or frequency offset detection. For example, a signal processing circuit may be operable to determine, for each of a plurality of downconverted signals, one or more frequency offsets that are associated with one or more corresponding local oscillators (LOs) used in obtaining the plurality of downconverted signals; and relating to the determined frequency offsets may be generated for the plurality of downconverted signals. The signal processing circuit may perform, based on the generated information, one or both of a band stacking operation and a channel stacking operation so as to prevent channels/bands being stacked on each other or being overlapped.

  • Patent number: 9686035
    Abstract: Presented are systems and methods for spectrum management and timing optimization of communication networks have multiple distribution points, multiple remote transceivers, and a shared communication binder. In some embodiments, distribution points and communication lines are added to an active network by the allocation of unused time slots. In some embodiments, transmission collisions, near-end cross-talk, and far-end cross-talk, are predicted upon the addition of added distribution points and communication lines, and techniques are applied to reduce or cancel such phenomena.

  • Patent number: 9681184
    Abstract: Exposing consumers to content of secondary interest via a content distribution network is becoming increasingly difficult as Video on Demand gains popularity and consumers isolate themselves from secondary content, including: new programs, emergency alerts, etc. Additionally, ensuring that the consumers are consuming secondary content that is provided to them via the content distribution network poses technical difficulties for the service provider. Therefore, systems and methods that encourage consumers to consume secondary content and verify its consumption non-intrusively are of increasing importance to service providers. Providing consumers with the ability to opt in and out of tracking and verification for the promotion of content allows consumers to be provided secondary content and for the service provider to appropriately reward the consumers for consuming the content to encourage additional consumption of secondary content.

  • Patent number: 9660960
    Abstract: Some embodiments provide reconfigurable web application firewall (WAF) functionality across a distributed platform. Specifically, the WAF function at each distributed platform server is customizable on a per customer and per inbound message basis. When a server receives an inbound message, the server identities the content or services of which specific customer are implicated by the inbound message. The server screens the inbound message for attacks using a first set of rules and policies defined as part of a production profile from a WAF instance defined by the specific customer while contemporaneously testing the inbound message against a second set of rules and polices defined as part of an audit profile from the same WAF instance. In this manner, the specific customer tests the audit profile rules and policies while still receiving the protections of the production profile rules and policies.

  • Patent number: 9642038
    Abstract: Disclosed are methods for offloading of communication traffic from a cellular network to a Wireless Local Area Network (“WLAN”). According to various implementations, a wireless device determines a time period during which a wireless channel of the WLAN is busy. This first time period may include multiple channel-busy periods separated by periods during which the channel is not busy. The wireless device determines a second time period that represents interframe spacings associated with the first time period. The wireless device determines a modified channel utilization for the wireless channel based on the first time period and on the second time period. The wireless device reports the modified channel utilization to the cellular network.
