The following is the format in which the trace file is being created

event
time
Source node
Destination node
Packet type
Packet size
flags
fid
Source address
Dest. address
Seq. number
Packet id

If you take a look at the frame format of a trace file, the 8th column is the flow id which you can extract using an awkfile.

Read more on awk file and how you can isolate or count sent and received packets along with flow id. Once you have that just divide the two.
