- #The file isiweb.tcl is a ns script that demonstrates how to use
- #the output of ModelGen (the set of CDF files in ./cdf) to simulate
- #the traffic collected at ISI/USC gateway link. To execute it,
- #assuming you already have ns installed in your system, type
- #"ns isiweb.tcl" from the command line. It takes ~1 hour on a
- #Red Hat Linux 7.0 Pentium II Xeon 450 MHz PC with 1GB physical
- #memory.

- # the set of tcl/awk/perl scripts are used to
- # compute the time series of traffic size for
- # both inbound and outbound ISI traffic from
- # the output of ns. The resulted time series
- # isi.time (inbound traffic) and www.time
- # (outbound traffic) can further be used to perform
- # wavelet scaling analysis

- # modelCDF is a perl script that are used to
- # generate, in a CDF format, the following
- # user-level statistics for further validation of
- # the model
- # (a) session inter-arrival
- # (b) number of pages per session
- # (c) page inter-arrival
- # (d) page size
- # (e) request size
- # (f) server popularity
- # The CDF flie is in 3-column format (take pagesize.dat.cdf for example)
- # 1st column: page size (in KB)
- # 2nd column: accumulated number of samples
- # 3rd column: accumulated probability
