  • Patent number: 9042252
    Abstract: An appliance receives packets that are part of a flow pair, each packet sharing an application protocol. The appliance determines the application protocol of the packets by performing deep packet inspection (DPI) on the packets. Packet sizes are measured and converted into packet size states. Packet size states, packet sequence numbers, and packet flow directions are used to create an application protocol estimation table (APET). The APET is used during normal operation to estimate the application protocol of a flow pair without performing time consuming DPI. The appliance then determines inter-packet intervals between received packets. The inter-packet intervals are converted into inter-packet interval states. The inter-packet interval states and packet sequence numbers are used to create an inter-packet interval prediction table. The appliance then stores an inter-packet interval prediction table for each application protocol.

  • Patent number: 8971210
    Abstract: A configurable network adapter has N analog front ends, each generating a receiver output and a transmitter input. In a first mode of operation, the analog front end receiver outputs are coupled to a MIMO equalizer, which is coupled to an outer receiver and to a first MAC input, with the first MAC having an output coupled to an outer transmitter, a MIMO modulator, and to the analog front end transmitter inputs. In a second mode of operation, one or more of the analog front ends is directed to a SISO modulator fed by a second outer transmitter coupled to a second MAC transmitter output. An associated one or more of the analog front end receivers is coupled to a SISO equalizer, and thereafter to an outer receiver and to the second lower MAC, thereby providing a first mode for a single MIMO adapter and a second mode for a MIMO plus independent PAN interface.

  • Patent number: 8958418
    Abstract: Various techniques can be used to handle frames within multi-stage switching fabric. For example, in one method, a frame and an associated frame header are received at a switching fabric stage. The associated frame header includes a first field and a second field. The method selects one or more fabric points of exit within the switching fabric stage, based on the second field. The first field is used to select one or more other fabric points of exit within another switching fabric stage, and thus two different fields within the associated frame header specify fabric points of exit. The method then sends the frame to the selected fabric points of exit within the switching fabric stage.

    Abstract: Open Shortest Path First (OSPF) Non-stop Routing (NSR) with frozen standby LSDB is described. A network element includes a first OSPF instance initially acting as an active OSPF instance and a second OSPF instance initially acting as a standby OSPF instance. The second OSPF instance receives LSAs from the first OSPF instance and installs the LSAs in its LSDB. The LSAs in the LSDB are only aged by the active OSPF instance. If and when the second OSPF instance becomes the active OSPF instance, the second OSPF instance then ages the LSAs in the LSDB and processes each of the LSAs according to the aging of that LSA, where processing includes one of purging that LSA and refreshing that LSA.

  • Patent number: 8953598
    Abstract: A method and a system for determining the existence of broadcast/multicast frames buffered in an access point (AP) are used to avoid wakening a station (STA) unnecessarily. The method includes: when receiving broadcast/multicast frames sent from a service network and/or multicast group, an AP sets a broadcast/multicast indication bit that associates the service network and/or multicast group to the valid state and sends frames that carry the broadcast/multicast indication bit to a STA; the STA determines whether there are broadcast/multicast frames buffered in the AP according to the associated service network and/or multicast group and the received broadcast/multicast indication bit. Embodiments of the present disclosure also disclose an AP and a STA. The AP can identify whether there are broadcast/multicast frames buffered in an AP.

  • Patent number: 8953473
    Abstract: A plurality of frame buffers of a communication device store input frames for respective flows, which are units of managing communication. A sequential scheduler and an adjustment scheduler cyclically visit the plurality of frame buffers to read a frame for external output from each frame buffer. The sequential scheduler reads one frame per a visit to each frame buffer at a speed lower than a communication speed of the communication device. The adjustment scheduler reads one or more frames per a visit to each frame buffer such that a restriction on read quantity defined by a reference value greater than the shortest frame size is imposed.

  • Patent number: 8953613
    Abstract: Methods, systems, and computer program products for providing dynamic Quality of Service (QoS) for connections to applications over a network are provided. The method receives a message associated with the application, wherein the message includes information identifying the connection to the application and information about the application. The method then determines, based on a set of rules defined for the application, a QoS level to apply to the connection, and applies the determined QoS level to the connection. The QoS applied to the connection corresponds to the application and not the QoS associated with a personal or home account QoS that would otherwise be applied to the connection.

  • Patent number: 8953570
    Abstract: A method of operating a radio frequency identification (RFID) system is provided. The method interrogates RFID tags with an RFID reader and provides at least some of the collected tag data to a mobile device that is unable to communicate with RFID tags using the over-the-air interface. In some situations, the RFID system obtains the current location of the mobile device and determines the location of a target tag relative to the current location of the mobile device. Locating the target tag in this manner involves the interrogation of a reference tag located at the mobile device, along with the target tag, using one RFID reader. The position of the target tag relative to the reference tag is calculated in response to the tag response signals obtained from the target and reference tags. Moreover, location of the target tag can be independently determined relative to the location of a mobile reader, by using a reference tag attached to a fixed reader or to the mobile reader.
