Objectives

The aim is to develop a software platform that
allows the deployment of controlled
experimentation scenarios in order to make the
testing of different environments easier.
TEST ENVIRONMENT BUILDER (TEB)

LabQoS (Laboratory for Quality of Service) will
focus on carrying experiments related to the
network performance measurement and the
impact of new services on end users.

Conclusions
LabQoS test platform allows experiments to be performed
with different combinations of parameters in a stable way.


Logic of the experimental adaptation is remarkable
It provides a common platform for researchers in order to
share tests (validating and reproducing them)

Some european initiatives (TMA, etomic, DIMES…) can be
potential users


Improvement for the QoSMeter measurement system
