AS Route Validation Using Sibling AS Correspondence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous system (AS) management solutions suffer from incomplete information management, leading to issues such as route hijacking and leakage misjudgments due to the lack of comprehensive sibling AS information.
Innovation Solution
A route management method that utilizes sibling AS identifiers to enhance route management by validating route messages based on sibling AS relationships, incorporating Resource Public Key Infrastructure (RPKI) information to improve accuracy and reduce misjudgments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional AS management solutions are used to manage AS, business announcement relationships, or original route information, then the management process is simple, but the information completeness is insufficient leading to route hijacking and leakage misjudgments
Solution Approach 1:
The patent applies preliminary action by obtaining and storing sibling AS correspondence information before performing route management. The system pre-acquires the correspondence between first AS identifier and second AS identifier, and uses this pre-obtained information to validate route messages, thereby preventing misjudgments of route hijacking and leakage.
Solution Approach 2:
The patent introduces sibling AS correspondence as an intermediary element that mediates between traditional AS management and route validation. This correspondence information acts as a reference standard that helps accurately judge whether route messages are legitimate, reducing misjudgments caused by incomplete traditional management information.
2Measurement precision
If sibling AS correspondence information is obtained and used for route management, then the accuracy of route management is improved, but the system complexity increases
Solution Approach 1:
The patent applies universality by designing a route management system that can handle multiple validation scenarios using the same sibling AS correspondence mechanism. The system uses the correspondence information for various purposes including route hijacking detection, leakage prevention, and general route validation, making the enhanced system versatile without proportionally increasing complexity.
3Reliability
If only traditional ROA or business relationship information is used for route validation, then the validation process is straightforward, but misjudgments of route hijacking and leakage occur
Solution Approach 1:
The patent applies composite materials by combining multiple types of validation information (traditional ROA information, business relationship information, and sibling AS correspondence information) to create a more robust validation mechanism. This composite approach to information validation reduces misjudgments while the systematic integration keeps complexity manageable.

AI summary
A route management and autonomous system (AS) management system and method. The method includes obtaining a correspondence, where the correspondence comprises a first autonomous system (AS) identifier and a second AS identifier, and where the correspondence indicates that the first AS identifier and the second AS identifier are sibling ASes, and performing route management based on the correspondence.
