[Ns-bugs] [Bug 831] New: Insufficient numerical precision of timestamped simulation time in the ascii trace file

[code@nsnam.ece.gatech.edu]

http://www.nsnam.org/bugzilla/show_bug.cgi?id=831

           Summary: Insufficient numerical precision of timestamped
                    simulation time in the ascii trace file
           Product: ns-3
           Version: ns-3.7
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: simulation core
        AssignedTo: ns-bugs at isi.edu
        ReportedBy: jakub.konka at strath.ac.uk
   Estimated Hours: 0.0


Overview:
The simulation time expressed in seconds and timestamped in the ascii trace
file has insufficient numerical precision, and can cause erroneous results
especially for high-speed wired data networks. 

Compare with bug 830 http://www.nsnam.org/bugzilla/show_bug.cgi?id=830

The only difference between the two bugs is in the underlying NS3 modules: in
ns-3-dev OutputStreamWrapper was responsible, in ns-3.7 AsciiWriter is.

In AsciiWriter module case, the bug can be fixed in exactly the same way as in
OutputStreamWrapper (see bug 830
http://www.nsnam.org/bugzilla/show_bug.cgi?id=830 ).
