Abstract:

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.
