questions on file format for traces

["Laura-Lei Liu" <Laura-Lei.Liu.liul@nortelnetworks.com>]

Hi there,

I had seen "c" appeared in the file for traces:

+ 1.45176 2 3 tcp 1000 ---- 1 256 769 27 48
......
d 1.46276 2 3 tcp 1000 ---- 1 256 769 27 48
- 1.47176 2 3 tcp 1000 ---- 1 256 769 27 48
......
c 1.47276 2 3 tcp 1000 ---- 1 256 769 27 48

I know "d" means drop, what does "c" mean here?

thanks for the help.

Laura
