Executive Summary

On-line end-to-end Service Level Agreement (SLA) monitoring is of key importance nowadays. For this purpose, recent researches have focused on measuring (when possible), or estimating (most of the times) network Quality of Service (QoS) and performance parameters. Up to now, all the proposed solutions have the drawback of requiring a huge amount of resources with low accuracy, generally leading to unscalable systems. The paper observes, however, that the accurate estimation of network QoS parameters is not necessarily required for SLA assessment. What is required is an efficient and scalable method to directly detect SLA violations.
