WWW Traffic Engineering Tool Interface
We have started developing a WEB-based interface for our traffic
analysis tools (msa and lb).
To access the interface you only need a java-capable WWW browser.
The current version of the interface is available
here.
The msa tool
The following executables are currently available:
*Note* that the above files are
compressed with gzip, so you will have to unzip them.
The source code is not available yet.
There exists a
man page, and
a collection of frequently encountered problems.
A sample trace file (MPEG-1 compressed
video of Star Wars) can be found here. The trace
contains 40000 epochs, with each epoch having duration 40 msec.
Note that the trace file MUST have the extension .tr

The lb tool
This is a program for estimating leaky or token bucket parameters
for data from a trace file. It can estimate leaky bucket parameters when
all traffic is to be conforming or when some percentage of the traffic
can be non-conforming.
The following executables are currently available:
