Today, peer-to-peer (P2P) traffic consumes the largest fraction of network bandwidth. The files shared by P2P communications are mostly copyright protected, and there are issues related to Quality of Service (QoS) support and billing of P2P traffic. Hence, scalable and accurate detection of peer-to-peer (P2P) traffic is a significant problem for network service providers. Flow-based detection methods employ characteristics of data flows such as the number of packets per flow to classify P2P and non-P2P traffic. Thus, they provide solutions to problems of port-based and signature-based detection such as P2P applications with dynamic ports, updating the signature database and encrypted packets. In this paper, a comparative evaluation of several flow-based P2P traffic detection methods that employ machine learning (ML) techniques is presented. Different from previous work, the effect of network parameters is taken into consideration in our evaluation. Furthermore a new verification approach based on custom-made data is presented which can circumvent the accuracy problems of the previous verification methods that use port-based or signature-based techniques for the accuracy evaluation.

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 ...
Hardware design and implementation of packet fair queuing algorithms for the quality of service support in the high-speed internet
Sanli, Mustafa; Schmidt, Şenan Ece; Guran, Hasan Cengiz (2012-09-05)
The increasing amount of real-time traffic carried over the Internet requires end-to-end quality of service (QoS) support. To this end, the QoS Schedulers, that are implemented in routers, assign the available bandwidth resources to packet flows according to their respective allocated rates. Packet Fair Queuing (PFQ) schedulers can provide fair service and low end-to-end delay bound to the traffic flows. However, they have higher implementation complexity compared to other algorithms, because of the require...
An intrusion detection based approach for the scalable detection of P2P traffic in the national academic network backbone
Schmidt, Şenan Ece (2006-06-18)
The share of peer-to-peer (P2P) protocol in the total network traffic grows day-by-day in the Turkish Academic Network (UlakNet) similar to the other networks in the world. This growth is mostly because of the popularity of the shared content and the great enhancement in the P2P protocol since it first came out with Napster. The shared files are generally both large and copyrighted. Motivated by the problems of UlakNet with the P2P traffic, we propose a novel method for P2P traffic detection in the network ...
Design and implementation of scheduling and switching architectures for high speed networks
Sanlı, Mustafa; Güran, Hasan Cengiz; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011)
Quality of Service (QoS) schedulers are one of the most important components for the end-to-end QoS support in the Internet. The focus of this thesis is the hardware design and implementation of the QoS schedulers, that is scalable for high line speeds and large number of traffic flows. FPGA is the selected hardware platform. Previous work on the hardware design and implementation of QoS schedulers are mostly algorithm specific. In this thesis, a general architecture for the design of the class of Packet Fa...
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,...
