+The scripts in this directory characterize flow a DPI-enabled VNF. The
+characeterization is split up into two steps. The first step (dpi1.py)
+searches for the traffic profile parameter boundaries. The second step
+(dpi2.py) takes as input the output of the first step and searches for
+the maximum sustainable throughput of a DPI-enabled VNF.
+
+To run the first script, use:
+
+ python2.7 ./dpi1.py -t TEST_SYSTEM_DESCRIPTIONS -o OUTPUT1
+
+TEST_SYSTEM_DESCRIPTIONS is a comma-separated list of systems where
+the syntax of defining each system is shown below:
+
+ user@ip:proxDir:cfgDir
+
+To run the second script, use:
+
+ python2.7 ./dpi2.py -t TEST_SYSTEM_DESCRIPTIONS \
+ -s SYSTEM_UNDER_TEST_DESCRIPTIONS \
+ -o OUTPUT2 -d \
+ -i OUTPUT1
+
+Finally, the results can be processed using the following command:
+
+ python2.7 ./maketable.py -i OUTPUT1 -j OUTPUT2 -o FINAL_TABLE
