  • Hardware and software methodologies for dynamic resource allocation in virtualized flexible-grid optical networks
    Patent number: 9621313
    Abstract: Embodiments of the present disclosure are directed to systems and methods for allocating spectrum of a flexible-grid optical network to a plurality of virtual links. Given a set of optical channels of different line rates and channel widths, a user can reserve one of the optical channels as a long-term reservation. The user can later elect to downgrade its optical channel to a smaller optical channel with lower line rate and less spectrum, for example, when the user's traffic demands decrease. The user may return (e.g., sell or de-allocate) an amount of unused spectrum to the carrier, and the carrier creates and manages a resource pool to gather unused spectrum from users. When the user's traffic increases, the user may obtain (e.g., purchase) additional spectrum from the carrier's resource pool and/or upgrade the user's optical channel to an optical channel having a higher line rate.

  • Intelligent file pre-fetch based on access patterns
    Patent number: 9614925
    Abstract: Files and/or file updates can be pre-fetched from a server to reduce file access periods as well as shift network usage from high traffic periods to low traffic periods. For example, a file that was previously expelled from a cache can be pre-fetched from the server prior to a future period in which a client is likely to re-access the file. As another example, a file update for a file that remains stored in the cache can be pre-fetched from the server prior to a future period in which a client is likely to re-access the file. The file update may then be used to update the stored file. The file and/or updated-file can then be provided directly from the cache to the client when the client re-accesses the file.

  • System and method for power control command for device-to-device transmissions
    Patent number: 9603108
    Abstract: A transmit power control rule for device-to-device (D2D) transmissions may not be necessary during periods in which no uplink transmissions are scheduled to be received by an enhanced Node B base station (eNB). When uplink transmissions are not scheduled to be received by the eNB, the eNB may send a transmit power control (TPC) command to a D2D capable user equipment (D2D UE) that instructs the D2D UE to perform a D2D transmission at a pre-defined transmit power level (e.g., maximum transmit power level). When uplink transmissions are scheduled to be received the eNB, the eNB may send a TPC command to the D2D UE that instructs the D2D UE to perform a D2D transmission at a transmit power level defined by a power control rule.
