experimentation and validation of models, architectures
and mechanisms in the field of networking. In the case of
the DiffServ framework, simulation is even more valuable,
due to the fact that an analytical approach of mechanisms
and services is infeasible because of the aggregation and
multiplexing of flows. In this work, we have extended the
functionality of a widely used simulation environment
towards the direction of realistic traffic generation and a
series of mechanisms defined by the DiffServ architecture.
The modules created are being presented and a case
study of a simulation scenario that exploits the
functionality provided by them is described.1 aBouras, Christos1 aPrimpas, Dimitris1 aSevasti, Afroditi  uhttp://telematics.upatras.gr/telematics/publications/enhancing-diffserv-architecture-simulation-environment
