Abstract: |
For the study and verification of our
mathematical model of RED-like active traffic management module a discrete simulation
model and a continuous analytical model were developed. However, for various
reasons, these implementations are not entirely satisfactory. It is necessary
to develop a more adequate simulation model, possibly using a different modeling
paradigm. In order to modeling of the TCP source, the RED control module, and
the process of their interaction it is proposed to use a hybrid
(continuous-discrete) approach. For computer implementation of the model the
physical modeling language Modelica is used. Because the language Modelica
has multiple implementations we have selected the OpenModelica compiler. The
hybrid approach allows us to take into account the transitions between
different states in the continuous model of the TCP protocol. The hybrid
approach simplified the consideration of the model due to the conversion of a differential inclusions into a set of differential
equations with discrete transitions. The considered approach allowed to obtain a simple simulation model of interaction between
RED module and TCP source. This model has great potential for expansion. It
is possible to implement different types of TCP and RED. Furthermore, it is
possible to use a hybrid approach not only for the simulation but also for
analytical modeling. |
