Dynamic LLM Enablement for Network Station Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Troubleshooting and monitoring tasks in modern computer networks, particularly in large deployments, are cumbersome and error-prone due to the limitations of using management frames like 802.11k measurements, which are difficult to log and trace, making network conditions largely opaque.
Innovation Solution
Implementing machine learning models, specifically large language models (LLMs), on both access points (APs) and stations (STAs) to facilitate network management by exchanging textual diagnostic prompts and responses, allowing STAs to determine how to best respond to network conditions, and modifying settings based on these responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If management frames (e.g., 802.11k measurements) are used for access points to retrieve RF conditions and metrics from stations, then network monitoring capability is provided, but the approach is cumbersome and error-prone with difficult logging and tracing
Solution Approach 1:
The patent replaces the mechanical system of manual management frame exchanges with an AI-based system that automatically analyzes network traffic and generates troubleshooting insights. The AI model processes raw network data and outputs actionable diagnostic information, eliminating the need for operators to manually configure and interpret management frames.
Solution Approach 2:
The system enables self-service troubleshooting by deploying AI models at the network edge (access points and stations) that autonomously monitor network conditions, detect issues, and generate diagnostic reports without requiring manual intervention. The stations themselves perform self-diagnosis by processing local network traffic through the AI model.
2Loss of information
If explicit management frames are used to retrieve network metrics, then specific RF conditions can be obtained, but network conditions remain largely opaque and determining which metrics to log remains an open issue
Solution Approach 1:
The patent transforms the approach by changing from discrete metric collection to continuous natural language analysis. Instead of selecting specific metrics to log, the AI model processes all available network traffic and translates it into natural language descriptions of network conditions, making the system adaptive to any condition without requiring pre-defined metric selection.
Solution Approach 2:
The AI model serves multiple functions simultaneously: it monitors network conditions, detects anomalies, generates diagnostic reports, and provides troubleshooting guidance. This single universal system replaces the need for multiple specialized management frames and metric collection mechanisms.
3Productivity
If machine learning models are deployed on stations for distributed network management, then troubleshooting efficiency is improved and network load is reduced, but device complexity increases
Solution Approach 1:
The patent segments the AI processing functionality from the core network infrastructure. Instead of requiring complex AI models in every station, the system uses lightweight AI agents at the edge that process only relevant local network traffic, while more complex analysis can be performed centrally if needed. This segmentation reduces the complexity burden on individual devices.
Solution Approach 2:
The patent introduces an intermediary AI layer that sits between the raw network traffic and the troubleshooting output. This intermediary processes and simplifies the data flow, translating complex network protocols into meaningful diagnostic information, thereby reducing the complexity requirements for both the stations and the central management system.
Data Source
AI summary
Techniques for improved network management and troubleshooting are provided. A set of packets are received, indicating, for each respective station of a set of stations associated to an access point in a network, machine learning support provided by the respective station. A textual diagnostic prompt relating to network conditions of the network is transmitted by the access point and to at least a first station of the set of stations. A textual response to the diagnostic prompt is received by the access point and from the first station, where the first station generated the textual response based on processing the textual diagnostic prompt using a first machine learning model. One or more network settings are modified based on the textual response.
