[ns] To trace the packets from the trace file

[Rahul Lanjewar]

Dear sir,

           How to distinguish and count the sent, dropped and received
packets from trace file? I only need the data packets(sent, received and
dropped) not control packets like ACK.
Please if there any tool to trace the .tr file then it is good for me.

Thanks and Regards
