In-Vehicle Data Traffic Classification via Virtual Network Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability to classify in-vehicle data traffic with granular accuracy, leading to reduced capacity to identify network usage and detect anomalies, and fail to manage data services consumed within vehicles effectively.
Innovation Solution
A method and system that classifies in-vehicle data traffic by defining network namespaces and using routing tables to channel traffic based on source and destination IP addresses, dynamically updating the tables through DNS and TLS packet inspection to route data through specific channels associated with known service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional service provider routing is used, then traffic routing is simple, but granular classification of data services is lost
Solution Approach 1:
The patent segments the network namespace into multiple virtual network interfaces (veth pairs), each dedicated to specific data services or service providers. This segmentation enables granular classification of traffic by routing different service types through separate interfaces, achieving precise measurement and control while maintaining manageable system architecture through modular organization.
2Measurement precision
If traffic monitoring is implemented, then network usage identification improves, but processing delay increases
Solution Approach 1:
The patent performs preliminary classification and routing configuration before traffic flow begins. By pre-defining virtual network interfaces and routing rules for different data services, the system eliminates the need for real-time analysis and decision-making during traffic processing, thus achieving accurate network usage identification without introducing processing delays.
3Measurement precision
If service-specific routing channels are created, then traffic classification accuracy improves, but device complexity increases
Solution Approach 1:
The patent creates a universal routing framework using virtual network interfaces that can handle multiple data services and service providers through a standardized mechanism. This multi-functional approach allows the same veth pair structure to serve different classification purposes, achieving accurate service-specific routing while avoiding the complexity of implementing separate specialized systems for each service type.
