> It's a bit different with NS Manual trace explanation. There are different messages and abbreviations in the trace file, depending on the version of ns-2 that you have and the type of trace you are doing. This link explains them all:
http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats#Old_Wireless_Trace_Formats - just search "SFs". It looks like you have the "new wireless trace format" and you are using the DSR (Dynamic Source Routing) trace format, and SFs is an event, namely the Flowstate, where Flowstate is a struct in ns-2. See here for a diagram of Flowstate's relation to other classes and files in ns-2: http://www.ece.uvic.ca/~emads/ns-2.29/struct_f_q_1_1flow_state.html Hope those links help you out. -- Sincerely, Candace Phelps 3rd Yr Honors CS Student Quoting uknown noname <[EMAIL PROTECTED]>: > > > [input] [input] [input] [input] > Hello > This is part of trace file (~/tcl/ex/out-test.tr) from tcl sript > using DSR (~/tcl/ex/wireless-test.tcl). > > s 127.936679222 _0_ AGT --- 0 cbr 512 [0 0 0 0] ------- [0:0 2:0 32 > 0] [0] 0 3 > r 127.936679222 _0_ RTR --- 0 cbr 512 [0 0 0 0] ------- [0:0 2:0 32 > 0] [0] 0 3 > s 127.940949843 _0_ RTR --- 1 DSR 32 [0 0 0 0] ------- [0:255 2:255 > 32 0] 1 [1 1] [0 1 0 0->0] [0 0 0 0->0] > r 127.942102650 _1_ RTR --- 1 DSR 32 [0 ffffffff 0 800] ------- > [0:255 2:255 32 0] 1 [1 1] [0 1 0 0->0] [0 0 0 0->0] > s 127.974476947 _0_ RTR --- 2 DSR 32 [0 0 0 0] ------- [0:255 2:255 > 32 0] 1 [1 2] [0 2 0 0->16] [0 0 0 0->0] > r 127.975809754 _1_ RTR --- 2 DSR 32 [0 ffffffff 0 800] ------- > [0:255 2:255 32 0] 1 [1 2] [0 2 0 0->16] [0 0 0 0->0] > .... > .... > SFs 150.773527127 _2_ 127 [2 -> 1] 1(0) to 1 > s 150.773527127 _2_ RTR --- 127 ack 60 [0 0 0 0] ------- [2:1 1:0 > 32 1] [48 0] 0 2 > r 150.787165430 _2_ RTR --- 94 tcp 1520 [13a 2 1 800] ------- [1:0 > 2:1 32 2] [49 0] 1 2 > r 150.787165430 _2_ AGT --- 94 tcp 1500 [13a 2 1 800] ------- [1:0 > 2:1 32 2] [49 0] 1 2 > > > It's a bit different with NS Manual trace explanation.
