hi,
when i tried to run script
wired-cum-wireless-sim.tcl (ns version: ns-allinone2.1b7a , running on Linux
redhat 6.2)
(Script attached below). There were 3 files created automatically, 2 of
them are:
1. file wired-and-wireless-out.tr and 2. file wired-wireless-out.tr i opened these files to see what its content. The
result are hundreds of trace entries.
is there anyone can explain to me
in file wired-and-wireless-out.tr
1. what does M, s and D mean (first column)? 2. what does each column mean in line 3 - line 6 M 33.00000 4194305 (83.36, 239.44, 0.00), (89.66, 283.49), 19.15 M 50.00000 4194307 (591.26, 199.37, 0.00), (369.46, 170.52), 3.37 M 51.00000 4194306 (257.05, 345.36, 0.00), (221.83, 80.86), 14.91 3. what does each column mean in line 7 -
