[ns] Fwd: help: DSR trace

[deng qianhua]

Hello

I am working with DSR in ns-2 trace. I want to analyse when the route is
unreachable , the packet is dropped and when the route is reestablished .  I
have found some trace lines SFESTs and SFs, for example

SFESTs 0.020076749 _0_ 0 [0 -> 1] 1(1) to 1 [0 |1 ]
SFs 0.041155504 _0_ 7 [0 -> 1] 1(0) to 1

In file "dsragent.cc" I found SF means "Flowstate",and SFESTs "Flowstate
establishment"  but what is their difference? Can they give me some
indication about the route broken or reestablished? Or which indicator
should I capture?

Thanks a lot
