Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems struggle to accurately distinguish between abnormalities in client terminals and network failures, often leading to erroneous detections and difficulty in identifying the root cause of communication state issues.
Innovation Solution
An abnormality monitoring method that involves transmitting requests to terminals, calculating network throughput, analyzing request and response sizes, transfer speeds, packet losses, and retransmission packets to determine if abnormalities exist in terminals or network paths, using a monitoring device connected to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional monitoring methods are used to accumulate performance information, then network quality state can be displayed, but it takes time to specify whether a failure has occurred in a client terminal itself or in the network between server and client terminal
Solution Approach 1:
The patent segments the monitoring approach by analyzing communication states of multiple terminals individually and comparing them. By dividing the network into multiple terminal-specific communication paths and analyzing each separately, the system can quickly identify whether an abnormality is isolated to a single terminal or affects multiple terminals, thereby rapidly specifying the failure location without time-consuming comprehensive analysis.
Solution Approach 2:
The patent applies local quality by examining communication states specific to each terminal rather than treating the network as a homogeneous whole. By monitoring individual terminal communication characteristics (response times, packet losses, retransmissions) and comparing them against each other and against normal thresholds, the system can precisely locate abnormalities at the terminal level or network level efficiently.
2Reliability
If comprehensive communication state monitoring is implemented for multiple terminals, then accurate abnormality detection is achieved, but the system complexity increases
Solution Approach 1:
The patent employs a universal monitoring approach where a single monitoring device performs multiple functions: it monitors communication states of multiple different terminals, analyzes various communication parameters (response time, packet loss, retransmissions), and provides unified abnormality detection for both terminal and network issues. This multi-functional design achieves comprehensive monitoring without proportionally increasing system complexity.
Solution Approach 2:
The monitoring system utilizes the terminals' own communication responses as the monitoring data source. Each terminal naturally generates communication traffic when responding to monitoring requests, and the monitoring device analyzes these self-generated communications to detect abnormalities. This self-service approach eliminates the need for separate dedicated monitoring agents or complex instrumentation on each terminal, reducing overall system complexity while maintaining high reliability.

AI summary
An abnormality monitoring method is a method for monitoring communication states of a plurality of terminals using a monitoring device connected to a network, the abnormality monitoring method including transmitting requests respectively to the plurality of terminals, receiving responses to the requests, calculating a throughput of the network based on transmission of the requests and reception of the responses, making a first determination of determining whether the communication states of the plurality of terminals are abnormal, based on the throughput, sizes of the requests transmitted respectively to the plurality of terminals, and any one or more of transfer speeds, packet losses, and numbers of retransmission packets in the received responses, making a second determination of determining whether an abnormality has occurred on communication paths between the monitoring device and the plurality of terminals, based on a result of the first determination, and outputting a result of the second determination.
