    摘要: In one embodiment, a device obtains, from a plurality of routers in a network, a set of routing policies that collectively specify a first set of paths in the network, a second set of paths in the network, and time periods during which traffic is to be rerouted from one of the first set of paths to one of the second set of paths in the network. The device identifies overlapping path segments of the second set of paths in the network. The device makes, based in part on the overlapping path segments, a prediction that two or more of the set of routing policies will cause congestion along paths with overlapping path segments. The device adjusts, based on the prediction, the set of routing policies, to avoid causing the congestion.

    摘要: An operating method of a computing device operated by at least one processor includes collecting traffic packets; extracting particular field data from the traffic packets, transforming the extracted particular field data to a vector with a reduced dimension for each traffic packet, and creating training data with the vector for each traffic packet; training a traffic prediction model with the training data, the traffic prediction model predicting from an input traffic packet a next input traffic packet and whether the next input traffic packet is abnormal; and predicting with the trained traffic prediction model a frequency of abnormal traffic packets to be input, and outputting an abnormal traffic warning by comparing the predicted frequency and a threshold.

    摘要: In order to enable prediction of communication having high quality requirements, this communication device is provided with: a determination unit that determines that a change has occurred in the communication state of communication which is performed, with a device connected to a network, by each of a first terminal and a second terminal communicating with the device; and a derivation unit that, when the change in the second terminal is determined to be being occurring in synchronization with the change in the first terminal, derives a second change time at which the change occurs in the second terminal, on the basis of a first change time at which the change occurs in the first terminal.

    摘要: A method of a first transportation vehicle for predicting channel load. The first transportation vehicle predicts a critical area with channel congestion of at least one communication channel, determines a propagation trajectory of at least one second transportation vehicle and compares the propagation trajectory of the at least one second transportation vehicle and the critical area. Based on the comparison, the first transportation vehicle then selectively transmits a message having information on the critical area to at least one second transportation vehicle. Also disclosed is a transportation vehicle for performing the method and a computer program having instructions for performing the method.

    摘要: A method for optimizing a predictive model for a group of nodes in a communications network includes receiving a tuples of data values, each tuple including state data representative of a state of a node, an action including a specification of paths for duplicating data packets from the node to a further node, and reward data that indicates a quality of service at the node subsequent to duplicating data packets through the paths specified by the action, determining a data value indicative of a performance level for the communications network on the basis of reward data of the tuples, evaluating a predictive model that outputs a set of data values for each node, the data values predicting a quality of service from duplicating data packets on the paths, and modifying the predictive model based on the predicted data values and the data value indicative of a performance level for the communications network.
