  • Patent number: 8041832
    Abstract: Embodiments of a system and method for distributing network data to multiple nodes in a data communications network is described. Two data communication channels are provided for each node in the network. While one of the communication channels carries routing and flow control protocol messages, as well as data, in both directions between network nodes, the other communication channel is configured to transmit data traffic—and only data traffic—in a single direction from the network data server toward all of the other nodes in the network. By using 100% of the available bandwidth for data traffic only, the speed at which data may be distributed throughout the network is maximized and the performance degradation caused by the congestion, collisions or packet loss that typically occurs in two-way data communication channels is avoided.

  • Patent number: 8014314
    Abstract: A digital subscriber link data network incorporates a throughput test server (TTS) to provide fault identification, isolation, and verification of DSL service availability and data rates. An asymmetric digital subscriber line (ADSL) terminal unit-remote (ATU-R) is connected to an ADSL terminal unit-central office (ATU-C) over a conventional copper loop or equivalent. Data connectivity via a packet switch provides access to high speed data networks, TTS connectivity and interfaces to service providers (SPS). Upon receiving a test request, a technician routes a customer to the TTS. The customer uses a web browser to access the TTS and download executable testing software, e.g., a JAVA applet. The applet causes test messages to be sent to and received from the TTS and computes upstream and downstream data rates that is displayed to the customer together with whether the measured data rates are consistent with a specified class of service.

  • Patent number: 8015602
    Abstract: Methods and apparatus for testing of Internet-Protocol packet network perimeter protection devices, e.g., Border Gateways such as Session Border Controllers, including 5 dynamic pinhole capable firewalls are discussed. Analysis and testing of these network perimeter protection devices is performed to evaluate the ability of such device to perform at carrier class levels. The efficiency of state look table functions as well as call signaling processing capacity, implemented in a particular perimeter protection device, are determined and evaluated. Proper performance and efficiency of such perimeter protection devices are evaluated as a function of incoming call rate and as a function of total pre-existing active calls. Various different network perimeter protection devices, e.g., of different types and/or from different manufactures, can be benchmarked for suitability to carrier class environments and comparatively evaluated. Test equipment devices, e.g.

  • Patent number: 8005192
    Abstract: Systems for monitoring, storage, and analysis of information in signaling messages, communicated from originating networks to a destination network through one or more intermediate networks are described. Correlation and comparison between signaling messages of interest sent from an origination network to signaling messages received by the destination network allows for the detection of inconsistent information, e.g., information fields in a communicated message that have been altered, either intentionally or unintentionally, by an intermediate carrier. The introduction of an additional communications path over which notification messages are forwarded from signaling monitoring equipment in the origination network to signaling monitoring equipment in the destination network allows for a significant reduction in the memory storage requirements at the destination network and in the amount of processing required to match, compare, and evaluate signaling messages.

  • Patent number: 8005463
    Abstract: A service is provided to cell phone subscribers to improve reachability. A home location register node maintains state information on a subscriber's cell phone status. Cell phone status information includes: off; on, registered and available to receive calls; on, registered but busy participating in an ongoing call; on, registered but temporarily unavailable; and on, registered but unattended. Temporarily unavailable is further qualified: poor reception location, high interference, cell throughput saturation, intentional user disposition. Long term unavailability may also be inferred and indicated depending on the device and/or system status. When a call to a subscriber's cell phone cannot be completed or is not answered, the service annunciates the reason to the calling party. The calling party can then make a more informed decision as to when to reattempt the call and is more likely to reattempt the call. The service is provided in conjunction with call forwarding to landlines phones and/or voicemail.

  • Publication number: 20110158100
    Abstract: Methods and apparatus for providing an Anti-Flooding Flow-Control (AFFC) mechanism suitable for use in defending against flooding network Denial-of-Service (N-DoS) attacks is described. Features of the AFFC mechanism include (1) traffic baseline generation, (2) dynamic buffer management, (3) packet scheduling, and (4) optional early traffic regulation. Baseline statistics on the flow rates for flows of data corresponding to different classes of packets are generated. When a router senses congestion, it activates the AFFC mechanism of the present invention. Traffic flows are classified. Elastic traffic is examined to determine if it is responsive to flow control signals. Flows of non-responsive elastic traffic is dropped. The remaining flows are compared to corresponding class baseline flow rates. Flows exceeding the baseline flow rates are subject to forced flow rate reductions, e.g., dropping of packets.

  • Patent number: 7970785
    Abstract: Sources of operational problems in business transactions often show themselves in relatively small pockets of data, which are called trouble hot spots. Identifying these hot spots from internal company transaction data is generally a fundamental step in the problem's resolution, but this analysis process is greatly complicated by huge numbers of transactions and large numbers of transaction variables to analyze. A suite of practical modifications are provided to data mining techniques and logistic regressions to tailor them for finding trouble hot spots. This approach thus allows the use of efficient automated data mining tools to quickly screen large numbers of candidate variables for their ability to characterize hot spots. One application is the screening of variables which distinguish a suspected hot spot from a reference set.

  • Publication number: 20110135298
    Abstract: A mechanism for adjusting or shutting off an optical signal within a network system is provided. The system may include a generating element for providing an optical signal and a bi-directional coupler for transmitting the optical signal to downstream components and fiber links and for transmitting a reflected optical signal based on the reflection characteristics of the downstream components to a converter element. The converter element converts the reflected optical signal to an electrical trigger signal that is used by a processing element to monitor the degradation or operational conditions within the network system. Based on the electrical trigger signal the processing element may adjust or shut off the optical signal at the generating element or at another element within the network system or another network system. The processing element may also send a communication signal to other elements or an operator to indicate unacceptable noise within the network system.
