Abstract: A clock oscillator, a clock oscillator production method and use method, and a chip including the clock oscillator are provided. The clock oscillator includes a resonator, a shock-absorbing material layer, and a base, and at least a part of the shock-absorbing material layer is located between the resonator and the base. In the clock oscillator, the shock-absorbing material layer is added between the resonator and the base, and the shock-absorbing material layer can effectively prevent a mechanical wave from being conducted between the base and the resonator, so that the resonator is protected from external vibration. This can ensure, when there is external vibration, that an output frequency of the resonator is not deteriorated and improve shock absorption performance of the clock oscillator.

Abstract: This application provides example methods for establishing a service path in a transport network and example systems. One example method includes, obtaining, by an automatically switched optical network (ASON) first node, a service path computation result path. The service path includes the ASON first node, an ASON last node, and at least one first edge network node. The method also includes sending, by the ASON first node, a path establishment request message to a downstream node. The path establishment request message carries cross-connection configuration information of the ASON last node and the at least one first edge network node. The method further includes receiving, by the ASON first node, a path establishment response message of the downstream node. The path establishment response message indicates that cross-connection configuration for the ASON last node and the at least one first edge network node is complete.

Abstract: A method for detecting and/or preventing overfitting in training of deep learning and neural network models. The method has a classifier-training method, an overfitting-detection method, and an overfitting-prevention method. The classifier-training method trains one or more classifiers using training histories and labels of one or more trained machine-learning (ML) models. The overfitting-detection method uses the trained classifiers based on the training history such as validation losses of a trained target ML model to identify an overfitting status of the trained target ML model. The overfitting-prevention method is performed during the training of a target ML model and uses the trained classifiers based on the training history of the target ML model to identify and preventing overfitting of the target ML model.

Abstract: This application provides an exception locating method includes: A first device receives a first exception signal which changes abruptly from a first communication signal when the first communication signal passes through a location of an exception on a first line. The first device receives exception alarm information which is sent by the second device after the second device receives a second exception signal, the second exception signal is a signal that changes abruptly from a second communication signal when the second communication signal passes through the location of the exception. The first device determines the location of the exception based on a first time interval, where the first time interval is an interval between time at which the first exception signal is received and time at which the exception alarm information is received.

Abstract: The disclosed apparatuses and methods are directed to data plane restoration in a network. A method comprises receiving a label-switched path (LSP) failure notification indicating a failure in a network; generating, by a node of the network, a fast-restoration (FR) message and transmitting the FR message to a second node of the message forwarding path. The FR message comprises: a plurality of forwarding instruction objects (FIOs) having forwarding instructions for the FR message for each node of a message forwarding path; and a plurality of label-switched path objects (LSPOs) having a restoration LSP data for each node of a protection detour path. Another method comprises receiving the FR message; generating a modified FR message based on the FR message; and transmitting the modified FR message to another node of the message forwarding path based on the FIO, prior to processing the FR message by the node.
