  • Patent number: 9078158
    Abstract: A method and apparatus are used to generate radio link control (RLC) protocol data units (PDUs). A data request for a logical channel is received as part of an enhanced dedicated channel (E-DCH) transport format combination (E-TFC) selection procedure in a medium access control (MAC). Upon determining the data field size, an RLC PDU is generated such that it matches the requested data from the E-TFC selection. The size of the RLC PDU generated can be greater than or equal to the minimum configured RLC PDU size (if data is available) and less than or equal to the maximum RLC PDU size. The data is then transmitted in the RLC PDU in a current transmission time interval (TTI).

  • Patent number: 8989050
    Abstract: Systems and methods are disclosed for graph-based distributed parameter coordination in a communication network. In general, discrete local parameters to be coordinated among communication nodes in the communication network and their respective performance metrics, or costs, are modeled using a factor graph. Based on the factor graph, a variant of the sum-product algorithm, namely the min-sum algorithm, is applied in order for the communication nodes, through iterative message passing with their neighboring communication nodes, to decide upon optimal values for the local parameters for the communication nodes that collectively optimize a global performance metric across the communication network. In one embodiment, the communication network is a wireless communication network. In one specific embodiment, the wireless communication network is a cellular communication network.

  • Patent number: 8934496
    Abstract: In one embodiment, a border node between a reactive routing network and a proactive routing network may receive an inter-domain route request (RREQ) from a requestor for a destination, and determines whether it knows the destination. In response to knowing the destination, the border node responds to the requestor. However, in response to not knowing the destination at the border node, when the border node is ingressing the inter-domain RREQ into the proactive routing network, it sends the inter-domain RREQ to each other border node of the proactive routing network. Alternatively, when the border node is ingressing the inter-domain RREQ into the reactive routing network, it sends the inter-domain RREQ into the reactive routing network.

  • Patent number: 8868679
    Abstract: Network communications, Web-based services and customized services using the Web-based services may be provided over a peer-to-peer network from a first peer to a second peer (e.g., automobile head unit) wherein the first peer has a separate connection to a more general server-based network such as the Internet. A communications device application based on a peer communications framework component in communication with a peer network stack on the communications device may work as middleware, with a connection to both a more general server-based network such as the Internet and to an external device, such as a head unit of an automobile. Although the communications device has a separate connection out to the Internet via a general network stack co-existing on the same communications device, the peer network stack and the general network stack are not directly connected.

  • Patent number: 8867560
    Abstract: A number of ports are configured in a linecard in a network device as dedicated ports and a remaining number of ports as shared ports. A total bandwidth allocated to the dedicated ports is computed. It is determined that available bandwidth at a central crossbar is greater than the total bandwidth allocated to the dedicated ports. The total data sent the central crossbar is rate limited to less than the available bandwidth at the central crossbar. First data associated with the dedicated ports is scheduled to the central crossbar using a first priority. Second data associated with the shared ports is scheduled using a second priority. A shared port data is scheduled based on a ration of a bandwidth requirement for the shared port as a fraction of overall bandwidth requirement for the shared ports.
