Dear colleagues,
I just would like to report a small problem I encountered in the use
of the sample trace file with the "Traffic/Trace" object.
The point is that the trace file (format) depends on the machine
architecture (byte order of 32-bit integers). The sample data in the
package "tcl/ex/example.trace" fails on my Intel x86 (Free-BSD) machine.
This possibly comes from the code of the "Tracefile::setup()" in
traffictrace.cc, which reads the trace file via fread into a buffer
as a character stream and later "Tracefile::get_next" copies
a two-word trace record as 32-bit integers.
So, I believe this problem occurs only if I read an R3000-generated
tracefile on Intel x86, etc.
Best regards,
