TCP network modeling in Matlab

Hi, I have been trying to model a network with SimEvents and Simulink for the tcp protocol. Is it possible to connect both TCP/IP sender/receiver instruments or other appropriate Matlab box/functions to a Matlab network model?

In other words, is it possible to connect the output of a Matlab TCP sender to a Matlab network model and then connect the input of a Matlab TCP/IP receiver to the mentioned network? Notice that the receiver ACK packets should also go through the network model in order to be received by the TCP sender.

Thanks in advance for any suggestions,
