item. Finally, another unique feature is the ability to execute video transmission simulations using
Evalvid-RA in conjunction with NS-2 via the Evalvid-RA Simulation tab.
The aforementioned TRAFIL features are handled by distinct business layer modules as shown in
Figure 14.1. The core module is the Main Processing module and is responsible for the identication
of the selected trace le’s type. Namely, it determines whether it is a normal, old wireless, new wire-
less, or a user-specied trace le. Moreover, it is responsible for parsing, processing, and storing the
trace le’s data to TRAFIL’s database if it is a new trace le or loading its data from the database
if it is a preexisti ...
