  • Patent number: 7099281
    Abstract: In accordance with the present invention, a portion of a packetized data stream is copied from a data network without interfering with the flow of the data in the network. A known test signal is then substituted for the information contained in each copied packet to prepare a pseudo-media packet stream. The known test signal is encoded and packetized using the same methods used for the copied data stream. The pseudo-media signal is then recovered from the pseudo-media stream using the same depacketizing and decoding methods to be used on the copied packetized data stream. The recovered signal is an accurate representation of the state of the media stream since it has gone through the same packetization/depacketization and encoding/decoding procedures and includes all of the same faults of the copied data stream. The subjective quality of the recovered signal is then measured providing an accurate measure of the subjective quality of the copied media stream.

  • Patent number: 7054308
    Abstract: An apparatus and method are provided for estimating the grade of service (52) and offered traffic (51) for voice over internet protocol calls at a gateway (2) bridging calls between a public switched telephone network (3) and an internet protocol network (4), the gateway (2) having a dial-control management information base. The method comprises the steps of periodically polling the dial-control management information base for dial peer traffic statistics (44), storing the polled data, estimating the carried traffic using the polled data (501), estimating the grade of service (52) by utilizing the Erlang-B formula in an inverse manner (502), operating on the estimated carried traffic obtained in the first estimating step (501), and estimating the offered traffic (51) using the estimated values for the carried traffic and the grade of service (52) obtained in the previous estimation steps (503). In a second embodiment of the invention, a system (FIG.

  • Patent number: 6925399
    Abstract: A method and system for estimating the location of an injection point of foreign signals in a network comprises the steps of measuring signal samples at two points along the cable network distribution system, correlating the two signal samples to estimate propagation delay differences between the measurement locations and the source, and calculating the location and magnitude of the ingress. The propagation delay, or time correlation, is proportional to the offset of the injection point from the midpoint between the measurement sites, where the two parameters are related by the velocity of propagation in the cable. The amplitude of the correlation peaks represent the magnitude of the ingress at that location. Sensitivity may be increased by time-averaging the output of the correlation step. Multiple sources and/or ingress and egress sites may be measured simultaneously.

  • Patent number: 6910135
    Abstract: A method and apparatus is disclosed for improving the security of computer networks by providing a means operating passively on the network for detecting, reporting and responding to intruders. The system is comprised of a plurality of intruder sensor client computers and associated event correlation engines. Resident in the memory of the client computer and operating in the background is a Tactical Internet Device Protection (TIDP) component consisting of a passive intruder detector and a security Management Information Base (MIB). The passive intruder detector component of the TIDP passively monitors operations performed on the client computer and emits a Simple Network Management Protocol (SNMP) trap to an event correlation engine when it identifies a suspected intruder. The event correlation engine, through the use of a behavior model loaded in its memory, determines whether the user's activities are innocent or those of a perspective intruder.

  • Patent number: 6907401
    Abstract: A portal switch is provided that controls participation of merchants in on-line aggregators, such as portals, used for buying and selling goods and services. Merchants may enable or disable participation in an aggregator site by turning on or off software settings. When participation is enabled, the merchant's site makes its catalog entries and merchant profile available to the aggregator. By enabling or disabling the switch, the merchant actively expresses a willingness to participate in (or, conversely, a desire to be excluded from) the aggregator.

  • Patent number: 6879572
    Abstract: The present invention relates to a system and method for dynamically limiting the power of all users of a CDMA digital data link to maximize throughput and reduce interference among users of the link. In the operation of the data link, the maximum power available from each user of the link is determined along with the minimum power needed from each user to meet its link service requirement, that is, quality of service and frame error rate requirements. The maximum to minimum power ratio is derived for each user and the lowest power ratio, that is, the power ratio closest to unity is selected and used to scale upward the minimum power levels of all users of the data link. The resulting power level establishes the interference margin or slack available for all users of the data link and the interference slack available for new users to be admitted to the data link.

  • Patent number: 6831945
    Abstract: A method is provided for monitoring transmission signal interference in a bi-directional transmission/reception system in which a modulated signal received at a receiver location is subjected at the receiver location to analog to digital (A/D) conversion by an A/D converter 3, an output of which is routed to an input of a digital demodulator 6 for demodulation. The method includes the steps of accessing the output of the A/D converter 3 before the output is subjected to demodulation by the demodulator 6 and storing the accessed data in a storage buffer 7. The data stored in the storage buffer 7 is available for inspection to assist in determining the presence of signal interference.

  • Patent number: 6754177
    Abstract: A method and system for controlling congestion in an ATM network comprises the steps of pre-allocating, for a pre-determined interval of time, a set of burst access parameters to a set of pre-allocated virtual paths between a set of source node and destination node pairs in the ATM network, and controlling, at the burst level, the traffic at each source node based on the pre-allocated set of burst access parameters and without communicating with other nodes in the ATM network. Specifically, the network, for a pre-determined interval of time, pre-allocates a set of virtual paths between each source-destination node pair in the network, pre-allocates a set of maximum permitted rates to the pre-allocated set of virtual paths, respectively, and pre-assigns a set of burst access thresholds to a set of service classes, respectively, in the pre-allocated virtual paths, where the pre-assigned burst access thresholds are less than or equal to the corresponding pre-allocated maximum permitted rates.

  • Patent number: 6745242
    Abstract: A system monitors performance in a network that includes several network resources. The system obtains a list of targets in the network. The targets include selected ones of the resources. The system sends a request to the targets, receives responses from the targets, and determines a status of the targets based on the received responses or a lack of responses from the targets. The system then analyzes the status of the targets to determine compliance with the service-level guarantee.

  • Patent number: 6700972
    Abstract: The present invention provides a method and system for processing and collecting, at a telephone network central office, information for a call directed to a call center prior to the call being received at the call center. A call is received for processing at a telephone network central office that is local to the call origination location. At the central office, a determination is made as to whether the destination number of the call is identified in a selected database. In response to the call destination number being identified in the selected database, the central office solicits the caller to provide requested information. An indication of the requested information received from the caller is included in a data packet associated with the telephone call before the call is transferred from the central office. The call, including the indication of the requested information, is routed to the call center.
