Abstract: Active monitoring of the network
performance (especially end-to-end delays) is essential to provide quality of service for VoIP
in a service overlay network, since the network layer performance measurement is not accessible to the overlay nodes.
In order to sample the network delay sufficiently and efficiently for delay analysis,
we formulated a bi-objective optimization problem with the goal of finding
the optimal sampling frequency that provides the maximal signal reconstruction accuracy at the minimal sampling cost.
We derive the optimal sampling frequency as a proportional fair and Pareto optimal solution to the bi-objective optimization problem.
