Network Device Abnormal Signal Detection and Bandwidth Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IP network devices lack the ability to detect abnormal input signals, manage network bandwidth effectively, and reroute data processing tasks, leading to issues like image quality degradation, system downtime, and inefficient data transmission due to irregular network bandwidth and the absence of suitable compression methods.
Innovation Solution
The IP network device and method involve transforming input signals into frequency bands and resolutions, comparing them with abnormal signal databases to determine normalcy, and dynamically adjusting data transmission based on bandwidth and layer architecture, allowing for rerouting of data processing tasks between network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional IP network devices transmit video data via network, then data transmission is achieved, but image quality degrades and discontinuities occur due to irregular network bandwidth
Solution Approach 1:
The patent implements dynamic bandwidth adaptation by allowing the network device to adjust transmission parameters based on real-time network conditions. The device monitors network bandwidth variations and dynamically adjusts video encoding parameters, transmission rate, and compression levels to maintain image quality while adapting to changing network capacity.
Solution Approach 2:
The patent changes transmission parameters including compression ratio, resolution, and frame rate based on network bandwidth conditions. When bandwidth is sufficient, higher quality parameters are used; when bandwidth is limited, parameters are adjusted to prevent degradation and discontinuities, thus resolving the contradiction between maintaining quality and adapting to variable bandwidth.
2Ease of operation
If conventional IP network devices use one routing address to access network, then network operation is simplified, but the device cannot detect abnormal situations or find alternative routers
Solution Approach 1:
The patent implements a feedback mechanism where the network device continuously monitors the status of its routing address and connected routers. When an abnormal situation is detected (such as router malfunction or address conflict), the device receives feedback about the network status and can automatically switch to alternative routing addresses or notify administrators, thus maintaining operation continuity while keeping the interface simple.
Solution Approach 2:
The patent prepares alternative routing addresses in advance before network problems occur. The device is configured with multiple potential routing addresses and can pre-test their availability, so when the primary address becomes abnormal, the device can immediately switch to a backup address without interruption, ensuring reliability while maintaining ease of operation.
3Productivity
If conventional IP network devices process and transmit large amounts of data, then data transmission capacity is increased, but system becomes over-loaded and experiences system-down
Solution Approach 1:
The patent implements load management by processing and transmitting only the necessary portion of data based on current system capacity and network conditions. Rather than attempting to process all incoming data regardless of system state, the device selectively processes data within safe capacity limits, preventing over-loading while maintaining high productivity through efficient resource utilization.
Solution Approach 2:
The patent enables the network device to self-monitor its own system load and automatically adjust its data processing rate. When the device detects it is approaching capacity limits, it autonomously reduces processing intensity or prioritizes critical data, preventing system-down conditions while maintaining optimal productivity through self-regulation.
4Speed
If conventional IP network devices transmit data without abnormality detection, then transmission speed is maintained, but abnormal signals are not detected and resource wastage occurs
Solution Approach 1:
The patent implements continuous abnormality detection that operates simultaneously with data transmission without interrupting the data flow. The detection mechanism runs in parallel, continuously analyzing transmitted data for abnormalities while maintaining transmission speed, thus preventing resource wastage from undetected abnormal signals while preserving high transmission speed.

AI summary
A network device and a method for controlling the same. The device and method each performed the operations of transforming an input signal so as to allow the input signal to be divided according to frequency bands and resolutions, comparing the transformed input signal with abnormal signal information stored in an abnormal signal database (DB), and determining whether the input signal is a normal signal. When the input signal is a normal signal, the network and method each perform the operation of delivering the transformed input signal to a codec.
