Chapter 25 in "The ns Manual" handles with trace issue. Maybe you can use "create-trace", "drop-trace", "trace-queue" etc.. instead of "trace-all". $ns_ create-trace <type> <file> <src> <dst> <optional:op> Here create-trace allows to define src and dst nodes that are to be traces. With type and optional:op you can further reduce the size of trace. I didn't find quickly how to set <optional:op> value though. Maybe someone on this list can help. Furthermore, "NS simulator for beginners" describes how to reduce size of trace files with gawk, perl, grep etc. under unix-based operating systems. Good luck. Regards, -- Luqman
