Motivation
The
growth of the number of hosts connected to the Internet and of new
applications increased the importance of research and development of
Quality of Service (QoS)-based networks. In order to optimize the
proposal and the validation of new QoS architectures and
technologies, simulation seems to be the best solution when
considering the deployment efforts, cost and scalability.
Unfortunately, the existing platforms and tools for simulating
QoS-based Networks either do not support all the architectures and
technologies or do not fully support their characteristics.
Basically, a simulation life-cycle can be divided into three phases:
specification of the scenario, simulation of the events and analysis
of the results of the simulation. This work presents a platform for
the specification of networks scenarios supporting QoS and multicast,
which can be simulated using ns-2.
This platform provides the author with the possibility of covering
all the three phases of the simulation life-cycle on-the-fly.
