Router Cold Start for Conflict-Free Net ID Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network systems face challenges in automatically resolving conflicts when integrating different sub-networks during router startup, particularly when integrating different systems with new routers.
Innovation Solution
A network system comprising routers with a cold start unit that initiates a tree structure connection, updates Net IDs through a Net ID server or manual settings, and performs data distribution to ensure unique Net IDs and conflict-free configurations, allowing automatic network configuration and integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a router verifies network configuration by broadcasting Net ID requests at startup, then conflict detection is possible, but automatic resolution of conflicts when integrating different systems is impossible
Solution Approach 1:
The router performs a cold start that proactively triggers downstream routers to also perform cold starts, initializing Net IDs before conflicts can occur. This preliminary action ensures that when routers are integrated into different systems, their Net IDs are reset and重新 assigned, preventing conflicts automatically without requiring manual intervention or complex verification protocols.
Solution Approach 2:
Each router automatically performs a cold start when triggered by an upstream router, and subsequently assigns itself a new Net ID through the Net ID server. This self-service mechanism eliminates the need for manual configuration or complex conflict resolution protocols, as each router independently ensures its own Net ID uniqueness through the cold start process.
2Reliability
If manual Net ID assignment is used, then Net ID uniqueness can be ensured, but automatic network configuration is not achieved
Solution Approach 1:
Routers automatically perform cold starts and request Net ID assignments from the Net ID server without human intervention. The entire process of ensuring Net ID uniqueness and configuring network parameters is handled autonomously by the routers themselves, combining the reliability of unique Net ID assignment with the convenience of automatic configuration.
Solution Approach 2:
The Net ID server acts as an intermediary between routers, automatically assigning unique Net IDs when routers perform cold starts. This mediator ensures Net ID uniqueness while allowing routers to automatically configure themselves, eliminating the need for manual Net ID assignment while maintaining reliability.
3Adaptability or versatility
If router data is updated during cold start, then new network configurations are recognized, but existing router data may be lost
Solution Approach 1:
The system performs a cold start as a preliminary action before integrating routers into new network configurations. This cold start initializes new Net IDs and configuration parameters, ensuring that routers are properly prepared for their new roles. The loss of old data is acceptable and intended, as the cold start is specifically designed to reset configurations when routers are moved between different network systems.

AI summary
A network system comprising routers and a plurality of sub-networks, each of which connects apparatuses, wherein the plurality of sub-networks are identified by respective Net IDs, and are connected via the routers to form a tree structure. Each of the routers includes: first and second communication interface units that connect multiple sub-networks; a router data storage unit that holds router data including the Net IDs of the respective sub-networks that are connected; and a control unit that performs a cold start, which is a start-up process involving an update of the router data stored in the router data storage unit, wherein the control unit, when performing the cold start, causes each of the routers connected to downstream sub-networks to perform a cold start.
