Hello friends,
 
I Ashutosh Sharma is currently doing job at Ahmedabad. I am right now working on Network Simulator based applications.
As I am new to this concept so I wanted to know that how can I grab a packet which is being transmitted on a link, then modifying that packet (means say altering the contents of the packet) and then forwarding the packet to the next node in the network.. It means I want to alter a packet and then want to forward it at some another time stamp. I am not getting how to write simulation script for this in NS and what are the functions available with OTcl language.
 
Thanks in advance
regards,
Ashutosh Sharma
