for QoS parameters benchmarking system. Section IV presents the experimental results and section V concludes This paper presents the design and implementation ofa the paper.benchmarking system for QoS (Quality of Service). The application generates traffic patterns, measures and com-II. Background putes the QoS parameters and stores and displays the results both in numerical and graphical form. The main QoS represents the network capability to deliver better advantages of this system are the traffic patterns comservices for the selected flows over different technoloplexity, the accuracy of the measurements and the user gies. The main goal of QoS is to provide priority includfriendly interface. The application is developed in C# ing dedicated bandwidth, controlled latency and jitter, and language for .NET platform and represents a part of a improved loss characteristics, which represent the main complex framework designed for developing QoS techQoS parameters. A service represents the traffic performnologies such as traffic identification and marking, queue ance provided to the client and is characterized by the and congestion management, traffic shaping and policy, QoS parameters. QoS techniques represent the implemenspecific protocols.tation specific methods, including traffic identification Keywords -QoS parameter, Traffic pattern, Benchand marking, queue and congestion management, link marking efficiency, traffic shaping and policy, specific protocols. The service and QoS techniques are different but strongly

This paper presents the design and implementation of an embedded system for real-time network flow identification. The system identifies data flows based on packet inspection. The main advantage of this system is that it reduces significantly the processing time required for the flow identification. For the hardware implementation, a Xilinx Virtex-II Pro FPGA device and the Xilinx Embedded Development Kit (EDK) software are used. This embedded system represents the first step for designing a reconfigurable router with QoS (Quality of Service) support.
