  • Patent number: 10419395
    Abstract: Accessing data stored on a remote server includes determining a first address of a first server where a block of data identified by a key has been moved from a second server to the first server, the second server having a second address. A first entry of a switch flow table of a datacenter network is updated to indicate that received packets with a destination address including the second address are to be overwritten with the first address. The data center network includes a plurality of physical network switches. A second entry in the switch flow table may be configured to forward packets with the first address to a first port associated with the first server and a first set of the switches. If the second entry is not already present in the table, the second entry may be inserted into the switch flow table.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for encoding frameless packets. One of the methods includes receiving a data payload to be transmitted. The data payload is partitioned into multiple payload words, each payload word being of a predetermined size. A first sync word is added to each of the multiple payload words. A control word comprising label and an error checking value is added. A second sync word is added to the label and error checking word. If one or more counter criteria are satisfied while transmitting the multiple payload words, an idle word is transmitted before transmitting the label and error checking word.

    Abstract: A video stream demultiplxer receives video streams comprising a selected current content channel and one or more adjacent content channels. Time stamp management is concurrently performed on the adjacent content channels while decoding the selected current content channel. Timing information such as Decoding Time Stamp (DTS) and Presentation Time Stamp (PTS) values, and/or random access points (RAPs) may be determined for pictures stored for the selected current content channel and the adjacent content channels. The determined timing information is utilized to determine a Program Clock Reference (PCR) value for each of the selected current channel and the adjacent channels for channel monitoring. A timebase, derived from a PCR rate that is determined based on the determined PCR value, is determined for decoding the selected current content channel. An adjacent content channel, which is primed during decoding of the selected current content channel, may be directly decoded for display if selected.

  • Patent number: 8958802
    Abstract: A base station can observe downlink communications of neighboring base stations of neighboring cells to determine operational parameters of these neighboring base stations in a process called sniffing. The base station ceases downlink transmission and/or uplink reception and initiates downlink reception for a duration in time and/or over frequency to form a sniffing window to observe the downlink communications of the one or more neighboring base stations. The sniffing window represents an area in time and/or frequency where downlink communications are not transmitted. The base station determines operational parameters based upon the downlink communications of the one or more neighboring base stations that are observed during the sniffing window.

  • Patent number: 8913703
    Abstract: Method, device and system for detecting a disturbance, e.g., at least one short mechanical impact (shock or vibration) on a clock of a slave device by detecting a non-typical variation of a tracking error, i.e., a tracking error having a deviation that exceeds a predetermined threshold, wherein such a non-typical variation can be determined by the deviation from a statistical measure, e.g., a variance or a standard deviation, such that the determination of the quality of a clock signal is advantageously allowed and thus suitable counter-measures are provided. The method, device and system are applicable for all kinds of technical systems comprising slave devices that have a clock, e.g., devices in industrial and automation systems. The method, device and system are also applicable in communication systems that use a protocol to synchronize the clocks of its devices, e.g., Profinet.

  • Patent number: 8908659
    Abstract: Methods and apparatus of slot time synchronization for coexistence of 5 MHz, 10 MHz, and 20 MHz systems in TV white space are provided. The methods and apparatus extend concepts used in traditional 802.11 applications in the MAC layer so that networks that overlap in frequency and space can have access opportunities to TV white space channels. Several passive mechanisms are described which use bits of traditional 802.11 MAC Management Protocol Data Units to receive information related to the slot time of other overlapped networks. An active approach is described that uses measurements from a radio resource measurement service to adjust the slot time of stations in a network to that of the lowest bandwidth overlapped network in frequency and space.

  • Patent number: 8861552
    Abstract: A self-stabilizing network in the form of an arbitrary, non-partitioned digraph includes K nodes having a synchronizer executing a protocol. K?1 monitors of each node may receive a Sync message transmitted from a directly connected node. When the Sync message is received, the logical clock value for the receiving node is set to between 0 and a communication latency value (?) if the clock value is less than a minimum event-response delay (D). A new Sync message is also transmitted to any directly connected nodes if the clock value is greater than or equal to both D and a graph threshold (TS). When the Sync message is not received the synchronizer increments the clock value if the clock value is less than a resynchronization period (P), and resets the clock value and transmits a new Sync message to all directly connected nodes when the clock value equals or exceeds P.
