to avoid further confusion: With respect to TCP GBN means to do RTO handling as defined in RFC 2988 (and more recent), i.e. we have one RTO per CONNECTION - in contrast to one RTO per PACKET (at least, this is my understanding of RFC 793).
Perhaps, I make a fuss of nothing, than I have to learn and to apologize, however at the moment, this causes some confusion....
