Solution Overview
Problem
Existing network monitoring systems require additional dedicated devices for monitoring terminal devices connected to a network, increasing costs and complexity, and struggle to accurately detect abnormalities in communication states without causing false alarms.
Innovation Solution
A communication relay device equipped with a CPU, memory, and a monitoring function that measures communication rates and calculates sampling values to detect abnormalities, allowing for real-time monitoring and notification of issues without the need for additional devices, using threshold values to differentiate between normal and abnormal states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated monitoring device is installed to monitor terminal devices connected to a network, then monitoring accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the monitoring function with the communication relay device (router/switch) that is already present in the network. The relay device performs both its primary function of forwarding data packets and the additional function of monitoring communication rates between terminal devices, thereby eliminating the need for separate dedicated monitoring devices and reducing system complexity while maintaining monitoring accuracy
Solution Approach 2:
The communication relay device is designed to perform multiple functions: it acts as both a communication relay device for data transmission and a monitoring device for detecting communication rates and abnormalities. This multi-functionality allows the same hardware infrastructure to serve dual purposes, reducing the need for additional equipment
2Reliability
If additional dedicated monitoring devices are installed, then monitoring capability is improved, but cost increases
Solution Approach 1:
The monitoring capability is merged into the existing communication relay device, which is already necessary for network operation. By combining these functions, the patent achieves reliable monitoring capability without increasing the number of physical devices in the network
Solution Approach 2:
The communication relay device performs self-monitoring by detecting communication rates between terminal devices through its own built-in capabilities. This self-service approach allows the device to monitor network conditions without requiring external dedicated monitoring equipment
3Measurement precision
If communication rate measurement is performed continuously, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The communication relay device performs periodic measurement of communication rates at regular intervals rather than continuous monitoring. This periodic sampling approach maintains adequate detection accuracy for identifying communication abnormalities while significantly reducing the energy consumption compared to continuous measurement
Solution Approach 2:
The device measures communication rates in a sampled manner rather than continuously, using partial measurements taken at specific intervals. This approach provides sufficient information for detecting abnormalities while avoiding the excessive energy consumption of continuous monitoring

AI summary
A communication relay includes a port configured to be connected to a terminal device, a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform: referring to a communication rate at the port; measuring the communication rate; and calculating a sampling value indicating a communication state based on the measured communication rate.
