NS3: Definition: The NS3 is a sturdy and Flexible simulation tool used for network topology simulation. This type of simulation is primarily used for research purposes and implementing this simulator for real-time simulation will be expensive. This simulator helps also develop education. And the simulated models afforded by the NS3 trace the method of packet data transmission and it can function even in large-scale networks.

“Through this article, we introduce you effective information about the toolkit called “Evalvid” and its functions in networking and the process of Evalvid NS3 stimulation applied over the Evalvid tool to perform the NS3 simulation. In this article, you can get a lot of information the regarding title, mainly in the research aspect!!”

Overview of Evalvid

It is a kind of toolkit that can be used to perform effective video transmission. The Evalvid can be used as a substitute for other simulation structures. In general, the video file transfer in Evalvid can be achieved with the help of more than one file. The Evalvid is much flexible as it can be implemented in any scenario and it is simple to integrate with any other simulator.

Advantages of Evalvid

• Estimates the quality of video transmission
• Evaluating the quality of the network both real or simulated
• Assessing the packet loss rates, delays, jitter, and the underlying network parameters
• Implementing SSIM, PSNR metrics
• Applying biased metric of video quality valuation
• Supports H.264, H.263, MPEG-4, and also AAC with the help of committed PEAQ and PESQ metrics

The above-mentioned advantages are the uses-in-need of the Evalvid in the current scenario of networking. It has a wide range of use among networking users and the functions of Evalvid don’t end with its uses. Let’s discuss the documents and data infrastructure of Evalvid as follows

Documenting and data structures of Evalvid

As we discussed earlier, the Evalvid is primarily used for effective video transmission. In case of that, when documenting Evalvid we must need a video source. Usually, in the Evalvid file, the video types of files are stored in the YUV format as it is the chosen method for all MPEG-4 codecs. Evalvid can produce the video streaming if it gets a single encoded video, which is also called the trace files that contain every relevant Evalvid data to get results.

Evalvid-RA

• The process of packeting in the MTU parameter occurs in the NS3 simulation process without concerning the limitations of macroblocks
• Evalvid-RA cannot integrate with EvalVid 2. x. because of this inefficiency, the user working with raw *.m4v files cannot work on the *mp4 media file format.
• So intimating the *.m4v files without some MTU setting is possible
• Typically the EvalVid-RA is a toolset for tracking the file simulation occurring in the video of types MPEG-4.
• Such simulation was formed by altering the unique EvalVid v1.2, which can be considered as the real NS3 interface and rendering NS3 by applying the rate-adaptive version of SVBR

The above functions and process are mentioned for the Evalvid-RA and it is considered as an important simulation toolkit for the file simulation tracing. Along with this, we provide you the tool list of Evalvid as follows.

The major tools of Evalvid

The basic structure of the Evalvid consists of three major tools

• PSNR
• MP4TRACE
• ETMP4

And the functions of the above tools based on the following parameters

PSNR

• Usage
  • psnr x y <YUV format> <src.yuv> <dst.yuv> >
• Parameters
  • x frame width
  • y structure height
  • YUV format: 420, 422, etc.
  • dst.yuv: partial video
  • source video: src.yuv

ETMP4

• Functions
  • The mp4 trace produces the video file
  • Simulating the sender’s frame
  • The operation of etmp4 produces the video file on the basis of “st”, “sd” and “rd” files and as original transmitted video at times
  • Also produces QoS metrics on debit, packet loss

These are the significant functions and parameters and uses of the MP4TRACE tool. This tool is considered to be the important one as it conducts the major NS2 simulation process in the Evalvid and its structure. In addition to the parameters, let’s take a look at the NS 3 simulator applied on Evalvid.
