GATEWAY DEVICE, IN-VEHICLE NETWORK SYSTEM, AND FIRMWARE UPDATE METHOD

A gateway device is connected via network(s) to electronic controllers on-board a vehicle, where at least one of the electronic controllers is implemented in a virtual machine. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether a first electronic controller satisfies a second condition based on second information, which is whether the first electronic controller includes a firmware cache for performing a pre-update firmware cache operation. The circuitry also causes, when the second condition is not satisfied, the gateway device to execute a proxy process, where the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, creates updated boot ROM data with the updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM and resets the first electronic controller with the updated firmware.

BACKUP SYSTEM AND METHOD
20230008688 · 2023-01-12 ·

A backup-source storage system extracts, as a pattern, forwarding target data to a backup-destination storage system among data written to a storage apparatus through a volume. The backup-source storage system determines whether the extracted pattern matches with a registered pattern in the backup-source storage system. When a result of the determination is false, the backup-source storage system registers the extracted pattern and forwards the forwarding target data to the backup-destination storage system. When the result of the determination is true, the backup-source storage system does not forward the forwarding target data.

In-app failure intelligent data collection and analysis

Intelligent collection and analysis of in-app failure data is disclosed herein. Upon an application failure in a client device, the client device may collect failure information uniquely identifying a specific failure and provide the failure information to an analysis system. The analysis system may identify a specific failure that identifies the application and a specific portion of the code in the application, based on the failure information and match an action correlated to the specific failure where the action is uniquely designed to resolve the specific failure in the application. The action may include instructions for the client device used to intelligently lead to a resolution of the specific failure. The analysis system may transmit the action to the client device to perform the action and provide any follow up information to the analysis server. The analysis server may use the information to further analyze the specific failure.

PROACTIVE IMPACT ANALYSIS IN A 5G TELCO NETWORK

Examples herein describe systems and methods for impact assessment in a Telco network. An impact assessment engine can receive a scenario that species a symptom for a network resource. The scenario can be specified on an administrative console. The impact assessment engine can construct failure signatures in a codebook matrix. The codebook matrix correlates problems at impacted network resources to network symptoms. Based on the scenario, the impact assessment engine can generate synthetic failure signatures and isolate a subset based on which of the synthetic failure signatures are most common. Then, the system can identify tenants and services in the Telco network impacted by the subset. This can allow administrators or an automated process to identify potential impacts before a scenario occurs.
