Designing an effective and high performance network requires an accurate characterization and modeling of network traffic. The modeling of video frame sizes is normally applied in simulation studies and mathematical analysis and generating streams for testing and compliance purposes. Besides, video traffic assumed as a major source of multimedia traffic in future heterogeneous network. Therefore, the statistical distribution of video data can be used as the inputs for performance modeling of networks. The finding of this paper comprises the theoretical definition of distribution which seems to be relevant to the video trace in terms of its statistical properties and finds the best distribution using both the graphical method and the hypothesis test. The data set used in this article consists of layered video traces generating from Scalable Video Codec (SVC) video compression technique of three different movies.

Designing an effective and high performance network requires accurate characterization and modeling of network traffic. This paper provides a study of the transmission, modeling, and analysis of variable bit rate (VBR) video, which is fundamental for designing protocols and for effective utilization of networks in video transmission. To meet the specified requirements of future networks, the scalable video codec (SVC) was chosen as the video compression standard. The main objective of this work was to propose a statistical model that will allow better coordination between generated SVC video traffic and original video traffic. The performance of the proposed model was evaluated by comparing the model with three existing lowcomplex statistical models using graphical and statistical measurements as well as cross-validation. For all evaluation techniques, the accuracy of the proposed model was evaluated, and the frame size distribution of the modeled traffic was found to match that of the original video traffic better than other existing models.

Abstract-New services and no cooperation among Internet service providers are challenges facing by Internet nowadays. This situation is known as network ossification which makes the deployment and testing of new network technologies very difficult. Virtual network has been found as a solution for this problem which may used to make certain isolated virtual networks, sharing the physical resources of the substrate network. Meanwhile, there are some other problems through making a virtual network. Consequently, there are several solutions which have been done as well. This paper focuses on three existing solutions that have been implemented and aims to address the features of those solutions Index Terms-Network virtualization, virtual network, bandwidth allocation.
