Engineering Contradiction Analysis
1Measurement precision
If existing measurement technologies are used, then network performance monitoring is simple, but burst bit rate measurement precision is insufficient
Solution Approach 1:
The measurement process is segmented into distinct components: capturing packet transfer times at sender and receiver, calculating one-way delay, estimating round-trip delay, and computing burst bit rate. This segmentation allows each component to be measured and calculated separately, improving overall measurement precision while maintaining manageable system complexity.
Solution Approach 2:
The system performs preliminary actions by capturing packet transfer times and calculating delays before the actual burst bit rate measurement is needed. The one-way delay is calculated in advance using captured timestamps, and round-trip delay is estimated beforehand, enabling accurate burst bit rate computation when required.
2Reliability
If accurate burst bit rate measurement is implemented, then service-level agreement compliance can be verified, but measurement and calculation complexity increases
Solution Approach 1:
The system implements feedback by capturing packet transfer times at both sender and receiver, using this information to calculate one-way delay, and feeding this delay measurement back into the burst bit rate calculation. This feedback mechanism ensures accurate compliance verification while systematically managing calculation complexity through structured computation steps.
Solution Approach 2:
The system performs preliminary measurements of packet transfer times and calculates one-way delay in advance, before compliance verification is needed. This preliminary action provides accurate baseline data for service-level agreement verification while organizing the complexity into manageable preparatory steps.
3Measurement precision
If network delay estimation is incorporated, then burst bit rate calculation accuracy improves, but calculation complexity increases
Solution Approach 1:
The calculation process is segmented into distinct steps: measuring one-way delay from captured timestamps, estimating round-trip delay separately, and finally computing burst bit rate using both delay components. This segmentation improves calculation accuracy by accounting for network delay effects while keeping each calculation step manageable and systematic.

AI summary
A method and apparatus for determining the burst bit rate for data in the transport layer of a network is described. The burst bit rate is determined by measuring the time for a total number of bytes to be transferred across a point in the network and adding that time to an estimated network delay. The total number of bytes transferred is then divided by the transfer time plus the estimated network delay thereby calculating the burst bit rate for the transfer.
