This paper describes a test platform for verifying the functionality of network protocols as well as optimizing their parameters. The test bed is made by using combined OPNET simulator and MATLAB development environment. This test platform connects OPNET network protocols simulator with MATLAB development environment in the way that OPNET runs simulations of network traffic, with predetermined parameter values, while MATLAB executes the script with a mathematical algorithm, which optimizes parameters listed in OPNET simulator. Video traffic is generally transmitted via UDP protocol on the transport layer in TCI/IP model. Recently, alternatives for the transmission of video traffic have emerged with the use of the transport layer TCP protocol. As an exemplary use of the test platform, we performed the analysis of these two approaches, in addition to their comparison using simulations.
