Automatic Routing Information Generation in Network Relay Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating routing information in network systems require manual setting of parameters, leading to potential communication errors and inefficiencies, especially when network configurations change or are complex, as they necessitate creating communication path databases or issuing routing table creation commands.
Innovation Solution
A routing information generating apparatus that includes a routing-information delivering section, a comparing section, and an updating section to automatically generate and update routing information across connected stations, eliminating the need for manual parameter setting and facilitating network configuration changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If routing parameters are manually set in relay apparatus, then routing information can be configured, but knowledge concerning networks is required and communication errors may occur due to setting mistakes
Solution Approach 1:
The relay apparatus automatically generates and updates routing parameters by receiving route information from terminal apparatus and other relay apparatus, comparing it with stored routing information, and self-updating without manual intervention. This eliminates the need for operator knowledge and prevents setting mistakes.
Solution Approach 2:
The system implements feedback by continuously receiving route information from terminal apparatus and other relay apparatus, comparing it with stored routing information, and automatically updating routing parameters based on the comparison results. This closed-loop feedback ensures routing information remains accurate and current.
2Ease of operation
If communication path database is created instead of routing table, then routing parameter setting is unnecessary, but data length to be transmitted decreases due to path information in communication message
Solution Approach 1:
The invention extracts only the essential routing parameters (relay destination network number and relay destination station number) from the full path information and stores them in a routing table. This eliminates the need to transmit complete path information in communication messages, reducing data length while maintaining automated routing functionality.
3Extent of automation
If routing table creation command is issued to create routing table automatically, then routing parameter setting is automated, but routing table must be recreated from beginning when network configuration changes
Solution Approach 1:
The system dynamically updates routing parameters by continuously receiving route information from terminal apparatus and other relay apparatus, comparing it with stored routing information, and selectively updating only the changed parameters. This dynamic approach allows the routing table to adapt to network configuration changes without complete recreation.
Solution Approach 2:
The relay apparatus preliminarily stores routing information in a routing table during initial setup, then uses this pre-established structure to efficiently compare and update only the necessary parameters when changes occur, rather than recreating the entire routing table from scratch.

AI summary
Network connecting sections of an own station deliver routing information notified from a relay section on the same base to network connecting sections of other stations of own networks. If new routing information is present in routing information received from the network connecting sections of the other stations, the network connecting sections of the own station notify the relay section on the same base of the routing information. The relay section updates, based on the routing information notified from the network connecting sections on the same base, routing information held by the relay section.
