Transmission of high quality video over the Internet faces many challanges including unpredictable packet loss characteristics of the current Internet and the heterogeneity of receivers in terms of their bandwidth and processing capabilities. To address these challanges, we propose an architecture in this paper that is based on the temporally scalable and error resilient video coding mode of the H.263+ codec. In this architecture, the video frames will be transported over a new generation IP network that supports differentiated services (Diffserv). We also propose a novel Two Rate Three Color Promotion-Capable Marker (trTCPCM) to be used at the edge of the diffserv network. Our simulation study demonstrates that an average of 30 dB can be achieved in case of highly congested links.

Improving performance of network intrusion detection systems through concurrent mechanisms Atakan, Mustafa; Şener, Cevat; Department of Computer Engineering (2003) As the bandwidth of present networks gets larger than the past, the demand of Network Intrusion Detection Systems (NIDS) that function in real time becomes the major requirement for high-speed networks. If these systems are not fast enough to process all network traffic passing, some malicious security violations may take role using this drawback. In order to make that kind of applications schedulable, some concurrency mechanism is introduced to the general flowchart of their algorithm. The principal aim is...
A Comparative Study on No-Reference Video Quality Assessment Metrics Zerman, Emin; Akar, Gözde; Konuk, Baris; NUR YILMAZ, GÖKÇE (2014-04-25) In the last two decades the Internet technology has boosted and the connection speeds have been incrased from kilobits to hundred megabits scale. With the rising coverage of the Internet and the usage of mobile devices such as tablets and smart phones, the usage of social media and especially multimedia elements has been increased rapidly. This increment in streaming multimedia created a need for the assessment of the user experience on multimedia and especially video. Even though there are different Video ...
The Development and hardware implementation of a high speed adaptable packet switch fabric Akbaba, Erdem Eyüp; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013) Routers have to be fast enough to keep pace with increasing traffic data rate because of the increasing need for network bandwidth and processing. The switch fabric component of a router is a combination of hardware and software which moves the incoming packets to the outgoing ports. The access of the input ports to the switch fabric is controlled by a scheduler which affects the overall performance together with the fabric design. In this thesis we investigate two switch fabric and scheduler architectures,...
A comparative study of evolutionary network design Kalkan, Sinan; Şehitoğlu, Onur Tolga; Üçoluk, Göktürk; Department of Computer Engineering (2003) In network design, a communication network is optimized for a given set of parameters like cost, reliability and delay. This study analyzes network design problem using Genetic Algorithms in detail and makes comparison of different approaches and representations. Encoding of a problem is one of the most crucial design choices in Genetic Algorithms. For network design problem, this study compares adjacency matrix representation with list of edges representation. Also, another problem is defining a fair fitne...
Performance of distribution networks under VBR video traffic Ozdem, Mehmet; Erten, Y. M. (2007-03-25) In this study we tested the average delay and packet loss performance of access networks under variable bit rate (VBR) video traffic. We used ns-2 simulator to perform the simulations, and actual as well as synthetically generated ON/OFF sources with ON and OFF times taken from exponential or Pareto distributions are used as inputs to the simulated networks. To make sure that the synthetic sources have vbr-video like characteristics we chose the parameters of these sources such that their Hurst parameter is...
