Dear Renata, Use of "grep" or "egrep" can speed up processing the trace file. Extract only relevant lines of traces by using pattern matching and pipe the extracted liines to perl or awk. For example, egrep "^r.*_0_.*cbr". There are A LOT more variations for the pattern matching. I would google both "grep" and pattern matching.
About the trace file size, the only handy solution might be NOT using traceall without changing simulation settings. Since trace file is a pure text file, the trace file size can be huge depending on your simulations. If you run the simulations LONGER with MORE packets, the size of trace file becomes larger. Good luck! Yours truly, Tae-hyung Kim !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
