Network Gateway Abnormal Log Storage and Boot Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internet service providers face difficulties in managing and analyzing abnormal statuses in network gateways due to differences in specifications, software versions, and settings, making it challenging to reproduce and diagnose issues, especially when gateways from various manufacturers reboot and lose operational information.
Innovation Solution
A network gateway system that includes a network interface, storage unit, and processing unit to detect abnormal statuses, generate and store abnormal log files, and automatically transmit them to an external server during booting, including device information and abnormal code details, allowing for convenient extraction and analysis of abnormal status information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gateway automatically reboots after abnormal status, then the gateway can recover from the abnormal state, but all operating statuses are lost and background workers cannot acquire relevant information
Solution Approach 1:
The patent implements preliminary action by detecting abnormal status and generating abnormal log files before the gateway reboot occurs. The processing unit continuously monitors system status and prepares diagnostic information in advance, so when the abnormal status triggers a reboot, the information is already captured and stored in the log file rather than being lost entirely.
Solution Approach 2:
The patent applies copying by creating a duplicate record of the operating status information in the form of abnormal log files. Instead of relying on volatile memory that is lost during reboot, the system copies critical status information to persistent storage, allowing background workers to retrieve and analyze the copied data after the gateway restarts.
2Adaptability or versatility
If gateways from different manufacturers with different software versions are deployed, then the gateway can meet diverse domain requirements, but it becomes difficult to reproduce and analyze abnormal statuses
Solution Approach 1:
The patent implements universality by designing an abnormal log file generation mechanism that works across different gateway models, manufacturers, and software versions. The processing unit uses a standardized approach to capture abnormal status information, creating log files with consistent structure and content regardless of the specific gateway hardware or software configuration, enabling uniform analysis across diverse deployments.
Solution Approach 2:
The patent applies parameter changes by adapting the log collection parameters and detection thresholds to different gateway configurations while maintaining a consistent output format. The system can adjust which parameters are monitored and how they are recorded based on the specific gateway model and software version, yet still produces standardized abnormal log files that facilitate cross-platform analysis.
3Productivity
If the gateway transmits abnormal log files during booting state, then the log file can be automatically uploaded to the external server, but network connection may not be stable during booting
Solution Approach 1:
The patent implements feedback by establishing a transmission status monitoring mechanism. After the gateway attempts to upload the abnormal log file during booting, the system receives feedback about whether the transmission succeeded or failed. Based on this feedback, the gateway can determine whether to retain the log file locally for later transmission or confirm successful upload and clear the file, enabling adaptive response to network conditions.
Solution Approach 2:
The patent applies periodic action by attempting log file transmission at regular intervals during the booting process rather than immediately. Instead of a single transmission attempt that might fail due to unstable network conditions, the system periodically tries to establish connection and upload the log file, increasing the probability of successful transmission while the gateway stabilizes its network interface.

AI summary
An abnormal recording system and the method for network gateway are related to the abnormal recording system including an external server and a gateway. The gateway includes a network interface, a storage unit, and a processing unit. The processing unit connects to the network interface and the storage unit. The network interface connects to the external server. The storage unit stores an abnormal log file. When the processing unit detects an abnormal status, the processing unit generates the abnormal log file according to the abnormal status, and in the booting state, sends the abnormal log file stored in the storage unit to the external server by the network interface.
