  • Patent number: 9319341
    Abstract: A plurality of frames of data are transmitted over a serial interface in a manner that limits interference on the interface. This involves generating a pseudo-random number and asserting a read control signal at a moment in time, wherein a timing of the moment in time is influenced by the pseudo-random number. In response to the asserted read control signal, a frame of data is read from a data buffer. The read frame of data is then transmitted over the serial interface. A number of alternative embodiments are possible, such as embodiments in which buffer read operations are triggered based on the buffer fill level, and other embodiments in which buffer read operations are triggered by a timer. By using the pseudo-random number to influence the buffer read operations, timing coherency between the reading of frames is made low, thereby limiting interference.

  • Patent number: 9288769
    Abstract: According to one embodiment, a wireless communication apparatus includes a generation unit, a control unit, a transmission unit, a reception unit and an analysis unit. The control unit sets, as a first value, a magnitude of a transmission power of the first frame, and sets, as a second value smaller than the first value, a magnitude of a transmission power of the second frame. The transmission unit transmits the first frame at a first time interval until an acknowledgement frame is received, and transmits the second frame at a second time interval until an accept frame is received. The analysis unit analyzes the request transmission power information. The control unit determines a transmission power of a data frame based on the request transmission power information.

  • Patent number: 9246760
    Abstract: Systems and methods for reassigning and implementing communication links in a network are described herein. The systems and methods described herein, reduce the amount of throughput loss that results when a network is expanded. The systems and methods generate distributions for the communication links that, when implemented, reduce the number of broken paths that occur in the expanding network. More practically, the systems and methods provide a heuristic for remapping communication links from a first link distribution to a second link distribution.

  • Patent number: 9237099
    Abstract: A device for emulating circuit switching in Ethernet using an Ethernet circuit header (ECH) includes a node of a network that is configured to receive a packet. A control module may be configured to determine that a destination address portion of a data frame associated with the packet matches a predefined format. A parser module may be configured to parse an ECH portion of the destination address to identify a circuit-identification (ID). A look-up module may be configured to look up the circuit ID in a circuit-ID table using at least one of a plurality of key options to generate a look-up-result data. The control module may be configured to use the look-up-result data to direct the packet to a destination interface of a destination node.

  • Patent number: 9203779
    Abstract: A media converter to enable Ethernet in thin-profile mobile devices. The media converter can be designed to interface with a thin-profile mobile device via a short-reach Ethernet link and to interface with a network device via a conventional Ethernet link. Protocol conversion is therefore obviated, while accommodating a low-profile Ethernet port in the mobile device.

  • Patent number: 9185596
    Abstract: Apparatus and methods are disclosed for avoiding data loss associated with a quality of service (QoS) reservation failure. One such method of wireless communication operable at an access terminal includes receiving a request from an access network for a preselected communication, establishing a radio link with the access network in response to the received communication request, transmitting a Quality of Service (QoS) reservation request message to the access network to request QoS in response to the received communication request, receiving a QoS reservation rejection message from the access network indicating a rejection of the requested QoS, transmitting a RESV request message to the access network in response to the QoS reservation rejection message, and receiving the preselected communication over a preselected flow in response to the RESV request message.

  • Patent number: 9173139
    Abstract: Provided are a terminal and a method for searching access points performed by a terminal supporting a multi-RAT (Radio Access Technology) in a wireless communication system. The method includes: receiving, by the terminal, information on one or more access points (APs) located within a cell coverage of a base station; determining whether there are any accessible APs within the cell coverage of the base station based on the received information; searching and selecting an AP according to the determining, wherein: if there are accessible APs, the terminal searches and selects the AP within a first time period, the first time period is shorter than a current time period for searching the AP, if there are no accessible APs, the terminal searches and selects the AP within a second time period, and the second time period is longer than the current time period for searching the AP; and accessing the selected AP.

  • Patent number: 9136815
    Abstract: A variable bandwidth filter includes a first filter branch in parallel with a second filter branch. The first filter branch includes a first resistance in series with an input and a first output, and N parallel paths across the first output. The second filter branch includes a second resistance in series with the input and a second output, and N parallel paths across the second output. A clock tunes the first and second filter branches to a center frequency. A combiner produces a difference signal including a difference between the output of the first filter branch and the output of the second filter branch to provide a filter output having an adjustable bandwidth with reference to a center frequency. The bandwidth is adjusted by changing a value of at least one resistor or at least one capacitor in one or more of the first filter branch or the second filter branch.

  • Patent number: 9118572
    Abstract: In one embodiment, a particular autonomous system border router (ASBR), in a control-plane media access control (MAC) learning (CPML) network, discovers other ASBRs in the CPML network, the particular ASBR and other ASBRs interconnected with respective ASBRs of a data-plane MAC learning (DPML) network. The particular ASBR calculates one or more internal shortest path first (SPF) trees rooted respectively at each of the other ASBRs in the CPML network, and upon receiving a MAC advertisement route for a given MAC address with a given next-hop IP address, it may determine a distance from the particular and each other ASBR in the CPML network to the given IP address based on the internal SPF trees. In response to the distance from the particular ASBR being shorter than the distance from each other ASBR, the particular ASBR is designated as a designated forwarder (DF) for traffic sourced from the given MAC address.

  • Patent number: 9088496
    Abstract: Improved debugging capabilities for network packet path tracing. Embodiments trace both the control and data planes. During control plane operations each switch appends its identity to the payload, providing a full trace of the control plan path. Responses containing the forward path payload are provided back at each hop, the responses being routing back by tracing back the forward direction control plane. The data plane is monitored by setting traps along the control plane path, with responses at each hop that indicate a given switch has been used being returned along the control plane path.
