Network Adapter Latency Statistics Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing approaches for exposing internal diagnostics and statistics in electronic systems are inadequate, as they either lack sufficient data for understanding latency-related statistics or overwhelm the system with excessive data, leading to performance issues.
Innovation Solution
The solution involves delegating to hardware the sampling of sufficient data to determine latency statistics associated with hardware processes. This is achieved by programming internal logic to measure execution time and provide data indicative of latency to a processing device, which then processes this data to determine statistical values such as average, median, maximum, and minimum latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If diagnostics counters and event loggers are used to expose internal hardware information, then hardware diagnostics can be provided, but the data is insufficient for understanding latency-related statistics
Solution Approach 1:
The patent extracts only the necessary latency-related information from the hardware processes by programming internal logic to measure and provide specific data (execution time, latency statistics) rather than exposing all hardware diagnostics. This selective extraction resolves the contradiction by providing sufficient latency information without the complexity of comprehensive diagnostic exposure mechanisms.
Solution Approach 2:
The patent introduces an intermediary mechanism (internal logic programmed to measure execution time) that sits between the hardware processes and the processing device. This intermediary selectively collects and provides only the latency-related statistics needed, bridging the gap between raw hardware operations and useful diagnostic information without exposing unnecessary complexity.
2Loss of information
If comprehensive internal diagnostics and statistics are exposed, then complete hardware behavior understanding is achieved, but the system is overwhelmed with excessive data
Solution Approach 1:
The patent extracts only the essential latency-related information from comprehensive hardware diagnostics, filtering out unnecessary data. By programming internal logic to measure and provide specific latency statistics rather than all hardware behavior data, the system avoids overwhelming the processing device while maintaining sufficient information for debugging and performance optimization.
Solution Approach 2:
The patent applies partial action by collecting and exposing only the necessary portion of hardware diagnostics (latency statistics) rather than comprehensive all hardware behavior data. This partial exposure approach provides sufficient information for effective debugging without the excessive data overload that would result from complete diagnostic exposure.
3Loss of information
If existing diagnostic approaches are used, then hardware information can be exposed, but real-time processing and online access to debug data is not enabled
Solution Approach 1:
The patent enables continuous real-time collection and processing of latency statistics by programming internal logic to continuously measure execution time and provide updated diagnostic data. This continuous action allows online access to debug information without the time delays associated with traditional batch diagnostic approaches, resolving the contradiction between data accessibility and real-time processing.
