Routing Table Updates for Automatic Multi-Network Path Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face difficulties in determining a communication path without user effort, especially when the subnet of a communication target device is not registered with the routing table, leading to potential connectivity issues.
Innovation Solution
A communication device with storage means and table management means that registers records with a routing table, including a destination network ID, full-bit subnet mask, and gateway IP address, allowing it to determine a communication path through multiple networks with a simple structure.

Engineering Contradiction Analysis
1Extent of automation
If a routing table is used to identify communication adapters for subnets, then communication path determination is automated, but connectivity issues occur when the subnet is not registered with the routing table
Solution Approach 1:
The system performs preliminary actions by automatically registering subnet information with the routing table before communication occurs. When a communication target device is detected, the system proactively adds the corresponding subnet entry to the routing table, ensuring that the subnet is ready for immediate communication without requiring manual configuration or risking connectivity failures.
2Measurement precision
If manual subnet registration is required, then routing table accuracy is improved, but user effort and complexity increase
Solution Approach 1:
The system implements self-service by automatically detecting communication target devices and registering their subnet information with the routing table without requiring user intervention. The communication device autonomously monitors network conditions, identifies new subnets, and updates the routing table independently, maintaining high accuracy while eliminating manual configuration efforts.
3Reliability
If existing routing table techniques are used, then network connectivity is maintained, but the structure becomes complicated and user effort is required
Solution Approach 1:
The routing table structure is designed with universality to handle multiple communication scenarios through a single unified mechanism. The same routing table that manages standard subnet routing also automatically accommodates new subnets and communication targets without requiring separate complex structures or manual configurations, thereby maintaining connectivity while simplifying the overall system architecture.

AI summary
A storage stores a routing table with which a record is registered. The record includes a destination network ID, a subnet mask, and a gateway IP address. A table manager registers a first record with the routing table and updates the routing table to indicate, as a default route, a second path through a second communication network. The first record includes, as the destination network ID, an IP address of a first communication device connected to a communication device through a first communication network, includes a full-bit subnet mask as the subnet mask, and includes, as the gateway IP address, an IP address of a first gateway connected to the first communication network or identification information of a first communication adapter. This structure can appropriately determine a communication path with a simple structure without user effort.
