  • Patent number: 10491507
    Abstract: In one embodiment, a traffic management system includes an input/output sub-system to receive route search requests from client devices, and a CPU to search a route database for a suitable match for the route search requests yielding routes. The input/output sub-system is operative to receive data related to traffic levels along the routes. The CPU is operative to calculate a score for each route, select N quickest routes, and allocate the N quickest routes among the client devices. A first and second client device are allocated a first and second quickest route from the N quickest routes, respectively, the first and second quickest route having a first and second score, respectively. The second score is different to the first score. The input/output sub-system is operative to send to each client device data about the route allocated to that client device. Related apparatus and methods are also described.

  • Patent number: 10469372
    Abstract: A method is performed at a source node in a network of nodes configured with a link state protocol, and in which at least some of the nodes are enabled for multiprotocol label switching (MPLS). The node discovers and stores a link state topology representing the nodes of the network, links between the nodes, path-costs for the links, and whether each link is enabled or not enabled for MPLS. The node determines one or more shortest paths from the source node to a destination node among the nodes based on traversing the link state topology and, while the node traverses the link state topology, detects whether each shortest path supports or does not support MPLS end-to-end dataplane continuity. The node programs an IP dataplane with each shortest path, and programs an MPLS dataplane with ones of the one or more shortest paths that support the end-to-end MPLS continuity.

  • Patent number: 10433306
    Abstract: It is proposed an example for mapping between a signal field and a data field used in a wireless local area network (LAN) system supporting a plurality of resource units (RUs). If a second channel (e.g., a 20 MHz band) is nullified and thus a physical layer protocol data unit (PPDU) is not transmitted, a signal field transmitted through a first channel may include allocation information regarding all data channels, and a signal field transmitted through the first channel is preferably duplicated on a third channel. In this case, a signal field transmitted through a fourth channel may include only allocation information for a data field corresponding to the fourth channel.

    Abstract: Methods and apparatus are provided for control overhead reduction. The UE configures one or more short transmission time interval regions over a normal TTI region shared by the UE and one or more other, each UE includes a self-contained control information sPDCCH occupying a control information region. The UE detects a cover signal, which indicates one or more resource elements in the sPDCCH control-information region that can be used for data transmission. The UE obtains data transmission from the REs in the SPDCCH control information region based on the detected cover signal. In one embodiment, the cover signal is a dedicated signal. In another embodiment, the cover signal is a common signal. In yet another embodiment, the cover signal is encoded in a downlink control information (DCI) intended for the UE. In one embodiment, the cover signal indicates one or more CCE REs to be excluded for data transmission.

  • Patent number: 10349342
    Abstract: A method may include detecting multiple system-information block (SIB) blocks and associated content. The associated content may be stored. The method may further include detecting multiple change flags associated with the multiple SIB blocks, each of the multiple change flags associated with one of the multiple SIB blocks. In response to detecting a change flag having a first change flag value, content of the SIB block associated with the first change flag may be reused. The first change flag value may represent an absence of a change to the content of the SIB block associated with the first change flag. In response to detecting the change flag having a second change flag value, the SIB block associated with the second change flag may be detected and the associated content stored. The second change flag value may represent a change to the content of the associated SIB blocks.
