Host Route Injection for Network Security and Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IP forwarding mechanisms in data networks are vulnerable to attacks like spoofing and denial of service, and the configuration of routers and routing protocols is complex, making them difficult to manage effectively.
Innovation Solution
A method and system that detect data traffic in a forwarding domain, inject a host route associated with the detected traffic, and update a forwarding table, allowing for comparison of host paths to subnet route paths and installation of the host route when they do not match, thereby enhancing security and simplifying routing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP forwarding devices such as routers are used to block attacks, then security against spoofing and denial of service attacks is improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The system enables forwarding devices to automatically detect data traffic and inject host routes into the routing table without requiring manual configuration. The device monitors its own forwarding decisions and autonomously updates routing information, eliminating the need for complex manual routing configuration while maintaining security through automatic attack prevention
Solution Approach 2:
The system implements a feedback mechanism where the forwarding device continuously monitors data traffic patterns and uses this information to dynamically update routing tables. By feeding back traffic detection results into the routing decision process, the system automatically adapts to network conditions and prevents attacks without requiring complex static configuration
2Reliability
If manual routing configuration is performed, then control over routing paths is improved, but ease of operation deteriorates
Solution Approach 1:
The forwarding device performs self-configuration by automatically detecting data traffic patterns and injecting appropriate host routes into the routing table. This self-service approach eliminates the need for manual routing configuration while maintaining reliable routing control, as the device autonomously determines optimal paths based on actual traffic observations
3Productivity
If host routes are injected based on detected traffic, then routing efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The system injects host routes based on detected data traffic patterns without requiring absolute precision in traffic measurement. By using partial observation of traffic flows and injecting routes proactively, the system achieves efficient routing while tolerating reasonable measurement imprecision, avoiding the need for highly precise traffic analysis
