Virtual Tap Monitoring for Cross-Protocol USN Handovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network monitoring devices face challenges in tracking client devices during handover procedures between different communication protocols, especially in virtual environments where network interfaces are consolidated and inaccessible.
Innovation Solution
Implementing a virtual tap system that allows monitoring devices to access and process virtual network data packets, converting security contexts, and querying databases to track client devices across protocol transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If network interfaces are consolidated into virtual environment, then device complexity is reduced and resource utilization is improved, but monitoring accessibility and tracking capability deteriorate
Solution Approach 1:
The patent introduces a monitoring device as an intermediary component that bridges the gap between the consolidated virtual network environment and external monitoring needs. This monitoring device captures and analyzes network traffic within the virtualized USN environment, enabling continuous tracking of client devices during handovers without requiring direct access to internal network interfaces.
2Reliability
If security contexts are maintained separately for different protocols, then security reliability is improved, but protocol transition smoothness and monitoring continuity deteriorate
Solution Approach 1:
The monitoring device implements feedback mechanisms by continuously capturing network traffic during handover transitions and analyzing security context changes. This feedback enables the system to verify that security contexts are properly maintained across protocol transitions, ensuring both security reliability and handover continuity through real-time monitoring and validation.
3Object-affected harmful factors
If internal network interfaces are made inaccessible, then network security is improved, but monitoring capability and troubleshooting ability deteriorate
Solution Approach 1:
The patent segments the monitoring function from the core network operations by introducing a dedicated monitoring device that operates independently. This segmentation allows the monitoring device to capture necessary network traffic for security and troubleshooting purposes without requiring direct access to internal network interfaces, thus maintaining network security while enabling monitoring capabilities through separate, controlled access paths.

AI summary
Systems and methods for USN monitoring via virtual tap is provided. A system may obtain, from a virtual tap, virtual network data packets associated with a first type of wireless communication protocol. The system may extract a first ID from the virtual network data packets. The system may query a first database associated with the first type of wireless communication protocol or a second database using a second type of wireless communication protocol using the first ID. The system may determine a second ID and a security context based on the query. The system may convert the security context from a first type to a second type of security context. The system may store the converted security context into a field based on the second ID.
