Abstract
The subjective service quality as perceived by the end-user is an aspect which
is often neglected in classic network monitoring. Yet it is the end-user who decides
whether he will continue to use the service or not. This is especially true for real
time services like Voice over IP telephony (VoIP), whose experienced quality heavily
depends on the current network situation.
In this paper we present a self-organizing concept for distributed monitoring of
the end-to-end quality, which will bridge the feedback gap between the user and
the provider. It is based on a simple and robust measurement mechanism, which
is running at the host of the end-user. As a proof-of-concept we implemented a
prototype of our architecture and show the practicability of our concept using VoIP
quality measurements.
