  • Publication number: 20150139023
    Abstract: A system and method for testing one or more wireless data packet signal transceiver devices under test (DUTs). Incoming data packets from a DUT are monitored to discern between data packets transmitted as part of a DUT calibration cycle or initial data packets being transmitted as the DUT transmitter circuitry settles at its new settings (e.g., transmit signal frequency or power), and later data packets transmitted following completion of the DUT calibration cycle or settling of the DUT transmitter circuitry. Following identification of these later data packets, the tester is so notified and begins the test procedure, e.g., capturing the data packets for analysis. Meanwhile, the tester has been allowed to remain in active use for other test purposes during DUT calibration cycles and settling intervals, thereby increasing testing efficiency and reducing overall test time.

    Abstract: In a software defined network having switches including first and last switches and intermediate switches, wherein a default routing path exists between the first and last switches, a system and method are provided for computing path latency. The method includes inserting a respective monitoring rule(s) in each switch, mandating for each switch, forwarding a received rule matching packet to a next switch, and further mandating for the first switch and the last switch, sending a PacketIn message to a controller. The method includes inserting, in each switch, a respective monitoring probe(s) matching the respective monitoring rule(s) in a same switch to initiate mandates specified by the respective monitoring rule(s) in the same switch responsive to an arrival of the packet thereat. The method includes time-stamping the PacketIn messages to generate PacketIn timestamps, aggregating the PacketIn timestamps, and estimating the path latency from an aggregation of PacketIn timestamps.

  • Patent number: 8976702
    Abstract: Devices, methods and instructions encoded on computer readable media are provided herein for estimation of the available bandwidth in a frequency channel shared by a first access point and at least one neighboring access point. In one example, an impact value that represents the impact of traffic associated with the neighboring access point on the first access point is calculated. Based on the impact value, a first utilization metric associated with the first access point is generated. The first utilization metric represents the bandwidth available on the frequency channel in the presence of the traffic associated with the neighboring access point.

  • Patent number: 8976703
    Abstract: A device receives, from a mobile device, a registration request when the mobile device moves to a new service area of a network, where the registration request includes a resource management (RM) extension and a performance monitoring (PM) extension. The device also inspects quality of service requirements of the registration request, identifies performance aspects of the registration request to be verified, and inspects performance monitoring information associated with the registration request to identify a performance monitoring test needed to make a resource management decision. The device further executes the performance monitoring test, collects results of the execution of the performance monitoring test, analyzes the collected results of the performance monitoring test, determines whether intervention related to network topology and configuration is possible, and accepts or rejects the registration request based on the analysis of the collected results of the performance monitoring test.

  • Publication number: 20150063158
    Abstract: Techniques are presented herein for enabling performance monitoring of flows within a management and provisioning tunnel used for communicating packets between a wireless controller and wireless access point devices. A wireless controller that is configured to communicate with at least one wireless access point obtains a packet to be sent to the wireless access point for wireless transmission in a wireless network by the wireless access point. The wireless controller identifies, based on the packet, traffic session flow information associated with the packet. The wireless controller encapsulates the packet with a tunneling header that comprises the traffic session flow information and sends the encapsulated packet to the wireless access point. The tunneling header may also comprise an application identifier (ID) associated with the packet.

    Abstract: A method for reporting uplink control information and a wireless communication device using the same are disclosed. The wireless communication device supports multiple component carriers (CC), and the proposed method includes following steps. When a base station requests the wireless communication device to transmit aperiodic channel state information (CSI) report of one or more downlink CC to the base station, but the CSI of the downlink CCs may be invalid, following steps are executed on the downlink CC. Full payloads of channel quality indicator (CQI)/precoding matrix indicator (PMI) corresponding to a plurality of selectable RI values of the downlink CC are respectively calculated. Additionally, an RI value of the downlink CC is selected according to the full payloads of the CQI/PMI corresponding to the selectable RI values.

  • Patent number: 8958424
    Abstract: The invention is directed to counting data packets marked according to tri-color marking techniques. Packets of a packet flow that are marked according to a three color (or tri-color) marking scheme are counted using a counter implemented on a ternary content addressable memory (TCAM). Advantages of some embodiments of the invention are to enable the use of generic and cost-efficient TCAMs to quickly obtain the counts of all three colors of packets in such a packet flow. These counts can be used to provide detailed statistics on characteristics of the packet flow, which can be useful for debugging and accounting purposes.
