  • Patent number: 11316750
    Abstract: A method, computer system, and computer program product are provided for peer risk benchmarking. Customer data for a first network is obtained, wherein the customer data comprises a role of one or more network devices in the first network and a plurality of risk reports corresponding to the one or more network devices, and wherein each risk report is associated with a particular dimension of a plurality of dimensions of risk for the one or more network devices. A network profile image is generated by processing the plurality of risk reports. A generative adversarial network generates a synthetic network profile image from the network profile image, wherein the synthetic network profile image does not include the customer data. A second network is evaluated using the synthetic network profile image to identify differences between the first network and the second network.

  • Publication number: 20220103586
    Abstract: A method, computer system, and computer program product are provided for network risk analysis. A plurality of risk reports relating to a network device in a network are obtained, wherein each risk report is associated with a particular dimension of a plurality of dimensions of risk for the network device in the network. A count of the plurality of risk reports is determined for each dimension of the plurality of dimensions of risk. A regression model is applied to determine a risk value for the network device in the network based on the count of the plurality of risk reports for each dimension and based a role of the network device in the network.

  • Publication number: 20090046770
    Abstract: The present invention discloses a method for avoiding false initialization of xDSL transceivers. Prior to the initialization of xDSL transceivers, the method includes: by the transmitting port of a first xDSL transceiver, sending a message about the transmitting port to the corresponding receiving port of a second xDSL transceiver; by the receiving port of the second xDSL transceiver, returning a response message to the transmitting port of the first xDSL transceiver according to the received message; by the first xDSL transceiver, judging the response message received by the transmitting port, and, if the received message has a certain relationship with the message sent by the transmitting port of the first xDSL transceiver, proceeding with the subsequent initialization process; otherwise, quitting the initialization process of the transmitting port. The method of the present invention prevents the xDSL transceiver or its ports from entering the false initialization state.
