Real-Time Maximum Time Interval Error Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for estimating maximum time interval error in data transmission networks are inefficient, requiring large storage capacity and computing time, especially for long sampling periods, and do not allow for real-time estimation.
Innovation Solution
A method that processes data samples by dividing long sampling periods into sub-intervals, storing intermediate results instead of raw data, and using peak detection functions to calculate the maximum time interval error, reducing storage and computing requirements while enabling real-time estimation.

Engineering Contradiction Analysis
1Measurement precision
If the entire plurality of data samples is collected and stored for long sampling periods, then the maximum time interval error can be estimated, but the storage capacity and computing time required increase significantly
Solution Approach 1:
The sampling period is divided into a finite number of sub-intervals, and the data samples are processed in each sub-interval to generate intermediate results. Only these intermediate results are stored, not the entire plurality of data samples. This segmentation approach significantly reduces the storage capacity required while still enabling accurate maximum time interval error estimation for the complete sampling period.
2Measurement precision
If the entire plurality of data samples is collected before calculation, then the maximum time interval error can be estimated, but real-time estimation is not possible
Solution Approach 1:
The method processes data samples as they are received and generates intermediate results for each sub-interval during the sampling period, rather than waiting until all data is collected. This preliminary processing enables real-time estimation of the maximum time interval error, as the intermediate results are progressively available and can be used immediately without requiring the entire dataset to be gathered first.
3Productivity
If data samples are processed in real-time for short sampling periods, then storage requirements are reduced, but the method must handle both short and long sampling periods effectively
Solution Approach 1:
The method dynamically adapts its processing approach based on the duration of the sampling period. A time threshold is defined, and if the sampling period duration is less than or equal to this threshold, the plurality of data samples is directly processed in real-time. If the sampling period exceeds the threshold, the sampling period is divided into sub-intervals and intermediate results are stored. This dynamic adaptation enables the system to handle both short and long sampling periods effectively while optimizing storage and computing resource usage.

AI summary
A method for use in connection with a data transmission network includes receiving a plurality of time interval error data samples over a sampling period and comparing a duration of the sampling period to a time threshold for the sampling period. If the duration of the sampling period is less than or equal to the time threshold for the sampling period, the method includes processing the received plurality of data samples so as to calculate in real time a maximum time interval error. However, if the duration of the sampling period exceeds the time threshold for the sampling period, the method includes dividing the sampling period into a finite number of sub-intervals and processing the data samples in each sub-interval so as to produce a respective intermediate result for each sub-interval. Each of these intermediate results is stored directly after it is produced, and these stored intermediate results are processed so as to estimate the maximum time interval error.
