The INET framework for the simulation tool OM-
NeT++ provides a TCP module, which can be used
for evaluating various Internet applications. However,
the implementation of this TCP module has not been
state of the art. Some important features of modern TCP
implementations { particularly Selective Acknowledge-
ments (SACK) and a complete Flow Control { have been
missing. In this paper, we rst introduce basicTCPmech-
anisms. After that, we introduce the extensions we have
made to theTCPmodule of INET. Finally, we show some
results of our performance evaluation.
