Measurement is a required process in high performance networks for efficient quality-of-service (QoS)
provisioning and service verification. Active measurement is an attractive approach because the mea-
surement traffic injected into the network can be controlled and the measurement tasks can be distrib-
uted throughout the network. However, the execution of measurement tasks in common parts of a
network may face contention for resources, such as computational power, memory, and link bandwidth.
This contention could jeopardize measurement accuracy and affect network services. This contention for
limited resources defines a conflict between measurement tasks. Furthermore, we consider two sets of
