In the 'TCP Conversations' (IPv4, IPv6) statistics window, please add a column
with a count of the number of times there are TCP data flow reversals for each
conversation.
I.e. count the number of times there is payload delivered below the TCP
protocol that is in a different direction than the last non-empty payload
packet in that same conversation. Please also document if (or not) the
implementation of this statistic includes retransmission events.
I'd suggest a statistics column header of "Flow Reversals" if you don't have a
better idea.
The intent of this statistic is to be able to predict to first order the impact
of additional application turn latencies if this same conversation were to be
mapped over various network latencies. The bandwidth information is already in
the statistic window. Adding application data flow reversal events would
support latency analysis from this same statistic window.
