  • Patent number: 9935870
    Abstract: Methods and systems are disclosed for selecting channels for routing signals in a multi-channel switching network. In an example implementation, pairs of the signals that can be routed together over one channel in the multi-channel switching network are determined. A model graph is generated that has a respective vertex for each of the signals. The model graph also includes respective edges for the determined pairs connecting vertices corresponding to signals of the pair. A subset of the edges that includes a maximum number of disjoint edges is determined. Pairs of signals represented by the respective vertices connected by the edge are routed over a respective one of the channels. For vertices not connected to an edge in the subset, the signals represented by the vertices are routed via a respective one of the channels.

  • Patent number: 9923761
    Abstract: A system may determine that a first device is available to transfer traffic via a network and that a second device is available to transfer the traffic via the network. A master mode may be enabled on the first device. The master mode, when enabled on the first device while both the first device and the second device are available to transfer the traffic, may cause the first device to advertise dynamic routing information associated with transferring the traffic. A slave mode may be enabled on the second device. The slave mode, when enabled on the second device, may cause the second device to suppress advertisement of virtual router redundancy protocol routing information associated with transferring the traffic. The system may provide, via the first device and the second device, the traffic via a dynamic network path across the network, and in accordance with the dynamic routing information.

  • Patent number: 9769220
    Abstract: A control apparatus determines one of a plurality of relay devices as a representative relay device to manage a relay destination of content data in a session to be established. In response to receiving a request for starting relay of content data, from a communication terminal, the control apparatus transmits, with a request for starting relay of content data, relay device identification information for identifying the representative relay device to a relay device connected to the communication terminal, to cause the relay device to further transmit the request for starting relay of content data to the representative relay device identified with the relay device identification information of the representative relay device.

  • Patent number: 9713120
    Abstract: A method for reducing paging traffic between a gateway (GW) and plural base stations (BSs) is provided when paging user equipments (UEs). A cache map, which records most-recently visited BSs of selected UEs, is used to limit the number of BSs in the paging of each selected UE, thereby reducing paging traffic. Furthermore, paging requests sent to the same BS node are grouped into one batch in generating a transport-layer payload, reducing the number of generated transport-layer messages. When used in a LTE system, piggybacking paging requests as provided by the SCTP reduces paging traffic and windowing/congestion control overhead at the transport layer. Transmission efficiency is thus improved. In addition, the number of paging requests sent out by the GW node per one paging interval is controlled to be not greater than a pre-determined maximum value to further limit paging traffic for avoiding occurrence of a paging storm.
