Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network quality measurement technologies, such as the Y.1731 Performance Monitoring method, face limitations in providing various metrics within a single frame, leading to increased network load and complexity in calculating accurate Service Level Agreement (SLA) parameters due to the need for multiple frames and overlapping metrics.
Innovation Solution
An improved method and apparatus for measuring and managing end-to-end SLA using an expanded Y.1731 Performance Monitoring frame that supports simultaneous measurement of multiple SLA metrics within a single frame, reducing network traffic and enhancing accuracy by hierarchically acquiring metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple measurement frames are used to satisfy complex test conditions and obtain various metrics, then measurement completeness is improved, but network load increases
Solution Approach 1:
The patent combines multiple separate measurement frames into a single integrated measurement frame that can simultaneously carry multiple metrics (delay, jitter, loss, throughput) and satisfy complex test conditions. This merging approach maintains measurement completeness while reducing the number of frames transmitted, thereby lowering network load.
Solution Approach 2:
The measurement frame is designed with multi-functionality to perform multiple measurement tasks simultaneously. The frame structure includes fields for various metrics and test condition configurations, allowing a single frame to serve multiple measurement purposes rather than requiring separate specialized frames for each metric.
2Measurement precision
If multiple measurement frames are used to obtain various metrics, then metric completeness is improved, but SLA calculation accuracy deteriorates due to overlapping metrics between frames
Solution Approach 1:
The patent segments the measurement frame into distinct fields, each dedicated to specific metrics (delay, jitter, loss, throughput) and test condition configurations. This segmentation prevents metric overlap between frames while maintaining completeness, as each field clearly defines its purpose and boundaries within the single integrated frame structure.
Solution Approach 2:
By merging multiple metrics into a single frame with clearly defined fields, the patent eliminates the overlapping metric problem that occurs when using multiple separate frames. The integrated structure ensures that each metric is captured exactly once without duplication or ambiguity, improving SLA calculation accuracy.
3Reliability
If conventional Y.1731 PM frames are used, then standard compliance is improved, but measurement capability is limited due to fragmentary metrics requiring multiple frames
Solution Approach 1:
The patent extends the conventional Y.1731 PM frame structure to provide multi-functionality while maintaining standard compliance. The enhanced frame can simultaneously measure multiple metrics (delay, jitter, loss, throughput) and support complex test conditions, making it universally applicable to various measurement scenarios without requiring multiple separate frames.
Solution Approach 2:
The patent nests additional measurement capabilities within the existing Y.1731 frame structure. The enhanced frame contains embedded fields for various metrics and test condition configurations nested within the standard frame format, allowing compliance with Y.1731 while adding extended measurement functionality.

AI summary
An operation method and apparatus in a first end device of a service provider network is provided. The method includes generating a measurement frame including information supporting simultaneous measurement of a plurality of Service Level Agreement (SLA) metrics, sending the generated measurement frame to a second end device connected through the service provider network, receiving a reply frame corresponding to the generated measurement frame from the second end device, and analyzing the received reply frame and hierarchically acquiring the plurality of SLA metrics for the second end device.
