Virtual Optical Network Management for Fault Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In constructing optical communication networks, simulators fail to detect unexpected faults that can occur when multiple communication devices are connected, making it difficult to optimize the network configuration effectively without affecting running optical paths.
Innovation Solution
An optical communication network management apparatus that maintains a virtual environment configuration close to the real environment by using a virtual environment configuration management unit to generate a virtual optical communication network, a configuration generation unit to create configuration data based on resource data, and a virtual and real environment optical path setting unit to set optical paths accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a simulator is used to design optical path and generate configuration commands, then the design process can be performed before actual device installation, but unexpected faults that occur when multiple communication devices are connected cannot be detected in advance
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the optical communication network that replicates the physical network's structure and behavior. This virtual environment allows testing and fault detection without affecting the actual deployed network, enabling detection of unexpected faults that occur when multiple devices are connected while avoiding the need for time-consuming physical reconfiguration and testing.
2Reliability
If intentional failures are caused in the actual optical communication network to optimize configuration, then network quality can be improved, but running optical paths may be affected
Solution Approach 1:
The patent introduces a digital twin as an intermediary between the physical network and the optimization process. By performing intentional failure tests and optimization experiments in the virtual environment rather than directly on the physical network, the system can improve network quality and detect configuration issues without causing any impact on running optical paths in the actual network.
3Adaptability or versatility
If multiple communication devices are connected to construct an actual optical communication network, then a functional network can be built, but unexpected faults cannot be detected by the simulator in advance
Solution Approach 1:
The patent performs preliminary testing and fault detection in the digital twin environment before the actual network is fully deployed or before configuration changes are applied to physical devices. By simulating various fault conditions and testing scenarios in advance in the virtual network, the system can identify and resolve unexpected faults before they affect the functional performance of the actual optical communication network.
