Re: MAC tracing in CMU

[Padmaparna Haldar <haldar@ISI.EDU>]

Juana,
      This is how the trace for wired-cum-wireless looks like at my end:

r 160.057492529 _2_ MAC  --- 3 DSR 44 [a2 0 3 800] ------- [1677
7984:255 16777216:255 255 16777216] 3 [0 2] [1 2 3 16777216->167
77984] [0 0 0 0->0]
s 160.057502529 _2_ MAC  --- 0 MAC 38 [0 3 0 0] 
f 160.057517529 _2_ RTR  --- 0 tcp 1492 [0 0 0 0] ------- [65536
:0 16777984:0 31 16777728] [0 0] 0 0
r 160.057655310 _5_ MAC  --- 0 MAC 38 [0 3 0 0] 
s 160.057784529 _2_ MAC  --- 0 MAC 44 [196e 3 0 0] 
r 160.057961310 _5_ MAC  --- 0 MAC 44 [196e 3 0 0] 
s 160.057971310 _5_ MAC  --- 0 MAC 38 [18cc 0 0 0] 
r 160.058124092 _2_ MAC  --- 0 MAC 38 [18cc 0 0 0] 
s 160.058174092 _2_ MAC  --- 0 tcp 1544 [a2 3 0 800] ------- [65
536:0 16777984:0 31 16777728] [0 0] 0 0
r 160.064350873 _5_ MAC  --- 0 tcp 1492 [a2 3 0 800] ------- [65
536:0 16777984:0 31 16777728] [0 0] 1 0
s 160.064360873 _5_ MAC  --- 0 MAC 38 [0 0 0 0] 
r 160.064375873 _5_ RTR  --- 0 tcp 1492 [a2 3 0 800] ------- [65
536:0 16777984:0 31 16777728] [0 0] 1 0

as you can see, the tcp pkt is sent from 2 to 5
(RTR(2)->MAC(2)->MAC(5)->RTR(5), along with other mac control and
routing message pkts.
see cmu/monarch's home page (http://www.monarch.cs.cmu.edu/cmu-ns.html)
for their added doc on tracing. they have a nice schematic that explains
how trace objects are placed/work in the wireless simulations.
