Abstract
In multiservice networks, QoS monitoring needs to be carried out in a
per-class basis so that each service class measuring requirements and
behavior are met and sensed properly. Facing the shortage of
off-the-shelf class-based monitoring solutions, this work is focused on
the development of a flexibly QoS monitoring tool oriented to
multiservice networks. In this context, after discussing main QoS
monitoring issues, we propose a flexible QoS monitoring Java
application, totally user parameterized and supporting service
differentiation. Benefiting from an edge-to-edge design perspective,
this service-oriented tool is able to make a periodic evaluation of
relevant QoS metrics for each service class, on an intra-domain or
end-to-end path basis. Monitoring results, stored in a MySQL database,
are useful to drive both online and offline traffic engineering and
service management tasks.
