  • Patent number: 9794184
    Abstract: Some embodiments provide a method for reducing congestion in a network stack that includes a series of components that send data packets through the network stack to a network. At a first component of the network stack, the method receives a data packet from a second component of the network stack. The method identifies a usage indicator value for a flow to which the data packet belongs. The usage indicator value is based on a comparison of a size of the flow to a size of a queue for a third component of the network stack. The method determines whether to send the data packet based on a comparison of the usage indicator value to a threshold usage value. The method sends the data packet to a next component of the network stack only when the usage indicator value is less than the threshold usage value.

  • Patent number: 9794804
    Abstract: Exemplary apparatuses and methods are provided that address how to optimize automatic neighbor relations. Specifically, a base station receives measurements from a mobile terminal connected thereto. The base station determines neighbor relations from the received measurements that includes identifiers of other base stations in neighboring cells detected by the mobile terminal. The base station determines a number of communication links needed to exchange data with the other base stations. The base station prioritizes the neighbor relations from a lowest priority level to a highest priority level before a maximum number of communication links needed to exchange data is exceeded. The base station may delete neighbor relations with the lowest priority level from the base station's Neighbor Relation Table so that the base station can support new neighbor relations, more efficient hand-offs, and improve network performance.

  • Patent number: 9774471
    Abstract: Transmission over a communication channel using carrier sense multiple access collision avoidance (CSMA/CA) may be performed by determining for each frame if the communication channel is busy after a backoff time proportional to a randomly generated number within a contention window (CW). When the channel is not busy, a frame of data may be transmitted. When the channel is busy, the device may periodically determine if the communication channel is busy after subsequent backoff times. The value of CW is adjusted for each subsequent backoff time using a fairness protocol, in which the value of CW is increased until the value of CW reaches a maximum CW value; and then the value of CW is held until a fairness number of backoff repetitions reaches a fairness threshold; then the value of CW is reduced incrementally until the value of CW reaches a minimum CW value.

  • Patent number: 9699090
    Abstract: A transfer device in a network including a plurality of control devices includes a network connection device, memory, and a processor. The network connection device communicates a target packet as a target of a transferring process. The memory stores a transfer rule received by the network connection device from a determination device as a control device for determining a transfer rule indicating a method of a process performed by the transfer device. The processor judges whether or not disable information indicating that the transfer rule is not to be acquired from the determination device when a transfer rule applicable to the target packet is not stored in the memory is included in the target packet. When the disable information is included, the processor outputs the target packet to the network connection device without requesting the transfer rule. The network connection device transmits the target packet to another transfer device.
