Relay Device Dynamic Forwarding Table Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current relay devices require cumbersome administrative processes for managing new devices in internal networks, including registration and setting up forwarding tables, which complicates device management and data transfer operations.
Innovation Solution
A relay device with a dynamic forwarding table that associates external and local port numbers and IP addresses, allowing for automatic updates based on device responses, application installations, and uninstallations, enabling efficient data transfer and device management by adding, deleting, or prohibiting port number associations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual registration and forwarding table setup is performed for new devices, then device management control is maintained, but administrative complexity and time consumption increase significantly
Solution Approach 1:
The relay device automatically performs forwarding table updates by detecting device connections and responses without requiring administrator intervention. The system serves itself by autonomously managing forwarding table entries based on device communication patterns
Solution Approach 2:
The relay device monitors device responses and uses this feedback information to dynamically update the forwarding table. The system continuously adjusts forwarding rules based on observed communication patterns between devices
2Manufacturing precision
If manual forwarding table configuration is performed, then precise data transfer routing is achieved, but time consumption and administrative burden increase
Solution Approach 1:
The relay device proactively detects device connections and pre-establishes forwarding table entries before data transfer is needed. By performing preliminary detection and configuration, the system eliminates setup time while maintaining routing precision
Solution Approach 2:
The system automatically detects devices and configures forwarding rules without administrator intervention, achieving both precise routing and time efficiency through autonomous operation
3Loss of information
If the forwarding table is manually updated, then accurate device information is maintained, but administrative workload increases
Solution Approach 1:
The relay device autonomously maintains forwarding table accuracy by detecting device connections and updating entries without administrator involvement. The system self-corrects and self-updates based on observed network traffic patterns
Solution Approach 2:
The system continuously monitors device responses and uses this feedback to maintain accurate forwarding table information. Automatic detection of device presence and communication patterns ensures information accuracy while eliminating manual updates

AI summary
To simplify setting operation in a relay device. State A illustrates a case where a source in an external network having transmitted the data to a router (4) is not associated with a transfer destination in a network system (1) in a forwarding table (40). In this case, the router (4) transfers the data received to all the devices (a PC server (2), a MFP (3), and a storage device (5)) in the network system (1) (arrows (A01) to (A03)). State B illustrates that the MFP (3) responds in accordance with the transfer of state A. State C illustrates that the router (4) changes the forwarding table (40) in accordance with the response of state B. In state C, the router (4) changes the forwarding table (40) such that information associating the source of the data of state A with the source of the response of state B is added.
