  • Patent number: 9674139
    Abstract: Presented herein are techniques to detect a misconfigured duplicate Internet Protocol (IP) address in a distributed data center network fabric. A network topology is provided that includes a plurality of network elements. A network element receives a configuration message comprising an IP address from a first host associated with the first network element. The IP address is detected to already be in use by a second host associated with a second network element. A request message is provided to the second network element, the request message configured to cause the second network element to attempt to contact the second host. A reply message is received from the second network element. If the reply message indicates that the second host exists at the second network element, an indication of a misconfiguration event is generated. Otherwise, the IP address is associated with the first host.

  • Patent number: 9647788
    Abstract: Techniques for multiplexing and demultiplexing signals for optical transport networks are presented. A network component comprises a multiplexer component that multiplexes a plurality of signals having a first signal format to produce a multiplexed signal in accordance with a second signal format, while maintaining error correction code (ECC) of such signals and without decoding such signals and associated ECC. The multiplexer component interleaves the plurality of signals with stuffing and adds overhead without generating new ECC. A second network component receives the multiplexed signal as part of a frame in accordance with the second signal format. A demultiplexer component of the second network component demultiplexes the multiplexed signal using the original ECC associated with the plurality of signals, wherein the second network element removes and filters the stuffing from the multiplexed signal and produces a plurality of demultiplexed signals as an output, in accordance with the first signal format.

  • Patent number: 9635644
    Abstract: Aspects of the present disclosure provide techniques and apparatus for enhancing downlink coverage for certain user equipments (UEs) (e.g., low cost, low data rate UEs). Certain types of UEs may have limited coverage or should receive enhanced coverage relative to other types of UEs. For example, some types of low cost UEs may have only a single receive chain, thereby limiting DL coverage, while other types of UEs benefit from multiple receive chains. One example method generally includes identifying a first type of one or more UEs that is to receive enhanced downlink (DL) coverage relative to a second type of UEs and utilizing one or more DL coverage enhancement techniques when communicating with the first type of UEs, the one or more DL coverage enhancement techniques designed to adjust at least for reduced DL processing gain of the first type of UEs relative to the second type of UEs.

  • Patent number: 9629020
    Abstract: A dynamic spectrum arbitrage (DSA) system may include a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DPC and DSC may store DSC context information, and use this information to perform various DSA operations. For example, the DSC may determine whether there is bandwidth available for allocation within cells in a first telecommunication network, generate a resource register request message that identifies the amount of bandwidth that is available, and send the generated resource register request message to the DPC using a DSAAP component/protocol. The DSC may receive the resource register response message and a bid success message via the DSAAP, and send a resources allocated message to the DPC via the DSAAP to commit the requested amount of bandwidth for use by the second telecommunication network.

  • Patent number: 9621479
    Abstract: IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

  • Patent number: 9578606
    Abstract: A method is provided for controlling transmission powers by a communication apparatus in a wireless communication system supporting a plurality of component carriers. When a sounding reference symbol (SRS) transmission overlaps with a physical uplink control channel (PUCCH) transmission in a time domain, the communication apparatus checks as to whether a total of a PUCCH transmission power for the PUCCH transmission on a first component carrier and a SRS transmission power for the SRS transmission on a second component carrier exceeds a maximum transmission power configured for the communication apparatus. The SRS transmission is dropped by the communication apparatus if the total of the PUCCH transmission power and the SRS transmission power exceeds the maximum transmission power configured for the communication apparatus.

  • Patent number: 9578389
    Abstract: A content delivery system and method that receives a request for a content stream that includes splice points. The method receives a playlist that includes an ordered list of media segment files that represent the content stream, and splice point tags, where generation of the media segment files aligns segment boundaries with the splice points in the content stream, and where each splice point tag is in a location in the playlist that corresponds to the position of one of the splice points in the content stream. The method identifies an insertion position in the playlist based on the location of the splice point tags, selects an advertisement segment, inserts the advertisement segment at the insertion position to create a modified playlist, removes the splice point tags from the modified playlist, and sends the modified playlist to the video display device.

  • Patent number: 9578632
    Abstract: In certain circumstances, the uplink resources (e.g., overhead) used for transmission of the UL DM-RS may be excessive, consuming an unnecessary amount of the available uplink spectrum. While there is a balance between the number of DM-RS and the reliability of the shared data channel, reduction of the UL DM-RS overhead may enable the UE to increase the number of transmissions in a UL subframes. Various DM-RS reduction techniques discussed include reducing the number of UL DM-RS generally, per resource block, or per pairs of resource units, and accommodating transmission of uplink control channel information when UL DM-RS is reduced. Further disclosed techniques relate to adjusting the number of UCI in the uplink shared channel.

  • Patent number: 9577887
    Abstract: Power Over Ethernet (POE)/universal power over Ethernet (UPoE) may be enabled at multigigabit port-channel connections. This may allow for additional speed support in auto-negotiation messages while employing multigigabit speeds. An integrated connector module (referred to herein as a “ICM”) compatible with UPoE with a modified local physical layer (PHY) circuit may be capable of supporting multi-gigabit data rates (such as between 1 G to 10 G, e.g., 2.5 G and 5 G) as to not limit the data rates to 1 G. The ICM may provide multi-gig data transmission through a first plurality of pins comprising a multi-gig data pin area. Furthermore, the ICM may provide UPoE power to support the multi-gig transmission through a second plurality of pins comprising a UPoE power pin area.
