I think you cn find example scripts in the ns dist tree. In fact
calculating packet drops can be done with 3-4 lines of awk

Nam is a good tool to see whether the network you have designed is working as you thought it would. However, I need to collet statistics on packet loss, and, most important, packet delay and make comparisons among different flows. I've searched through NS manual but surprisingly there doesn't seem to be a solution for that.
