Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network systems, there is a challenge in accurately determining whether a network apparatus is operating as an operation system or a non-operation system, leading to potential incorrect actions during failure recovery, such as PKG resetting, which can result in service not being restored due to lack of correct information.
Innovation Solution
A system determination apparatus and method that calculates a variation coefficient representing traffic variation and average traffic amount using traffic data, and determines the system based on the density of this data, classifying it as an operation or non-operation system based on predefined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic or manual path switching is performed in a redundant network system, then service continuity is improved, but deviation between configuration information and current situation occurs
Solution Approach 1:
The patent implements a feedback mechanism where the management system receives notification information from transmission apparatuses about their current system status (operation system or non-operation system). This feedback loop allows the management system to update its configuration information to reflect the actual current situation, thereby resolving the deviation between managed configuration and real state while maintaining service continuity through automatic path switching.
Solution Approach 2:
The transmission apparatuses autonomously determine their own system status (operation system or non-operation system) and notify the management system of this self-determined information. This self-service approach eliminates the need for manual configuration updates and ensures that configuration information automatically reflects the current redundant system state, preventing information deviation while enabling reliable path switching.
2Device complexity
If transmission apparatus does not have information about operation system/non-operation system, then device complexity is reduced, but operator may perform incorrect operations during failure recovery
Solution Approach 1:
The patent introduces notification information as an intermediary mechanism that conveys system status from transmission apparatuses to the management system. This intermediary allows the management system to obtain accurate information about operation system/non-operation system status without requiring complex direct communication protocols or additional configuration management complexity, thereby enabling reliable failure recovery operations.
Solution Approach 2:
The transmission apparatuses perform preliminary action by determining their own system status in advance and notifying the management system before failure recovery operations are needed. This preliminary information provision ensures that when failures occur, the management system already has the necessary configuration information to perform correct path switching and recovery operations without increasing operational complexity.
3Ease of operation
If operator performs PKG resetting without correct system information, then ease of operation is improved, but service restoration is prevented
Solution Approach 1:
The management system uses feedback notification information from transmission apparatuses to automatically determine which apparatuses are operation systems and which are non-operation systems. This feedback mechanism provides the management system with the precise information needed to perform PKG resetting operations only on the correct apparatuses, thereby maintaining service restoration reliability while keeping operations simple through automated information provision.
Solution Approach 2:
The transmission apparatuses self-determine their system status and provide this information to the management system, enabling the management system to automatically identify the correct apparatuses for PKG resetting. This self-service approach eliminates the need for operators to manually identify correct apparatuses, maintaining operational simplicity while ensuring service restoration by providing accurate apparatus identification information.
