# Ahmet's notes on TCP:
# 1. Delayed ACKs disabled by default, i.e. every segment received
#    by the receiver triggers an ACK.
# 2. If TCP runs "message mode", that is, with
#    MsgBasedSendQueue/RcvQueue configured in omnetpp.ini,  app
#    sends a 100MB cMessage over TCP, it'll be only passed up to the 
#    app on the receiver side when all 100MB has arrived. In contrast, with
#    VirtualBytesSendQueue/RcvQueue any data gets passed up immediately 
#    to the app (as a blank cMessage with the length set).
