Hi, I am trying to understand the trace of simple-wireless.tcl in ~ns/tcl/ex. The trace seems quite different. Can any one tell me where can I find the explanation of the fields ? Thanks, Dhiman s 0.267662078 _0_ RTR --- 0 message 32 [0 0 0 0] ------- [0:255 -1:255 32 0] s 1.511681090 _1_ RTR --- 1 message 32 [0 0 0 0] ------- [1:255 -1:255 32 0] M 10.00000 0 (5.00, 2.00, 0.00), (20.00, 18.00), 1.00
