Tunnel Service Support Server for Automated IPv6 Address Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional tunnel service systems, users must manually set and update the address of the tunnel router, which is cumbersome and inefficient, especially when the router's address changes or a new tunnel router is added.
Innovation Solution
A method and system where a tunnel service support server automatically transmits the tunnel router address to the user node, using DHCPv6 or NDIPv6 protocols, allowing the user node to store and utilize the address for communication through IPv6 networks, thereby simplifying the setup and management of tunnel services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually set the tunnel router address in the user node, then the address configuration can be directly controlled, but the operation becomes cumbersome and time-consuming, especially when address changes or new routers are added
Solution Approach 1:
The patent introduces a tunnel service support server as an intermediary between users and tunnel routers. This server automatically manages address allocation and updates, eliminating the need for users to manually configure tunnel router addresses. The server receives address requests from user nodes, assigns appropriate addresses, and notifies users of changes, thereby resolving the technical contradiction by making the system easier to operate while reducing time loss.
Solution Approach 2:
The tunnel service support server implements self-service functionality by automatically managing its own address allocation and update notification processes. When a new tunnel router is added or an address changes, the server autonomously identifies the change, selects appropriate user nodes to notify, and sends notifications without requiring manual intervention. This self-service mechanism resolves the contradiction by enabling easy operation through automation while minimizing time loss.
2Adaptability or versatility
If the tunnel router address changes or a new router is installed, then the network can adapt to new configurations, but users must directly set the changed or new address which is inefficient
Solution Approach 1:
The patent implements a feedback mechanism where the tunnel service support server continuously monitors tunnel router configurations and automatically detects address changes or new router installations. When changes are detected, the server generates notifications and sends them to relevant user nodes. This feedback loop ensures the network adapts to changes efficiently while maintaining high productivity, as users receive automated updates rather than manually checking for changes.
Solution Approach 2:
The tunnel service support server performs preliminary actions by proactively identifying address changes or new routers before users need to configure their nodes. The server prepares and sends notification messages in advance, allowing users to automatically update their configurations without manual intervention. This preliminary action resolves the contradiction by enabling network adaptability while preserving productivity through automation.
3Extent of automation
If a tunnel service support server is introduced to automatically manage address allocation, then user intervention is reduced and management is simplified, but the system complexity increases
Solution Approach 1:
The tunnel service support server is designed with multi-functionality, serving as an address allocation authority, change detection mechanism, and notification system all in one component. By consolidating these functions into a single universal server rather than distributing them across multiple specialized components, the patent achieves high automation while minimizing the increase in system complexity. The server handles address assignment, monitors router configurations, and manages notifications, thereby resolving the contradiction between automation extent and system complexity.
Data Source
AI summary
A system providing a tunnel service capable of data communication between different types of networks. A method of setting an address of a tunnel router in a user node includes: transmitting a message requesting at least one tunnel router address to a tunnel service support server; receiving a message including at least one tunnel router address from the tunnel service support server; and storing the tunnel router address included in the received message. According to the system and method, the address of a tunnel router providing a tunnel service to a user node can be more easily set, and even when the address of the tunnel router changes or a new tunnel router is added, the address of the tunnel router can be easily set without the user manually changing the address of the tunnel router.
