This paper discusses the problematic of QoS monitoring, suggesting the use of on-line multipurpose active monitoring in multiclass networks as a powerful tool to efficiently assist and enhance the control of multiple service levels. To improve the simultaneous estimation of one-way QoS metrics, we propose a flexible probing source able to adjust probing patterns to the measurement requirements of each service class, exploring pattern coloring to better sense packet loss. The proof-of-concept provided shows that the proposed solution improves the estimation accuracy of multiple QoS metrics significantly, with a reduced probing overhead.
