Method Detail

performAnalysis

public void performAnalysis(Flow flow_of_interest)
                     throws java.lang.Exception

Performs a separated flow analysis for the flow_of_interest.

This analysis first blends out the flow of interest and then computes for each server along this flow's path the left-over service curve that results if all remaining flows crossing this server receive their maximum amount of service. Then all left-over service curves are concatenated to receive the end-to-end service curve from the perspective of the flow of interest.

Throws:

java.lang.Exception
