meaning of "A" in trace file

[Maya Yajnik <yajnik@gaia.cs.umass.edu>]

Hi,

I am tracing an ns simulation and find a flag being set in the trace file.
For example, I have

+ 1.24141 0 1 tcp 1000 ---A--- 1 0.0 1.0 31 106
- 1.24141 0 1 tcp 1000 ---A--- 1 0.0 1.0 31 106
+ 1.7414 0 1 tcp 1000 ---A--- 1 0.0 1.0 31 107
- 1.7414 0 1 tcp 1000 ---A--- 1 0.0 1.0 31 107
r 1.8422 0 1 tcp 1000 ---A--- 1 0.0 1.0 31 107

If you have any ideas on what the "A" there means, please let me know.
Thank you, in anticipation.
