چکیده

Network emulation is a technique that allows real-application performance assessment under controllable and reproducible conditions. We designed and implemented a hardware network emulator on an FPGA-based custom-design PCI platform. Implementation was facilitated by the use of the Handel-C programming language, that allows rapid development and fast translation into hardware and has specific constructs for developing systems with concurrent processes. We report on tests performed with web-browsing applications.

An FPGA-based coprocessor for ATM firewalls

An agile firewall coprocessor is described that is based on field programmable gate array (FPGA) technology. This implementation of the firewall enables a high degree of traffic selectability yet avoids the usual performance penalty associated with IP level firewalls. This approach is applicable to high-speed broadband networks, and Asynchronous Transfer Mode (ATM) networks are addressed in par...

A multi agent method for cell formation with uncertain situation, based on information theory

This paper assumes the cell formation problem as a distributed decision network. It proposes an approach based on application and extension of information theory concepts, in order to analyze informational complexity in an agent- based system, due to interdependence between agents. Based on this approach, new quantitative concepts and definitions are proposed in order to measure the amount of t...

Hybrid Swarm Optimized ARMA Model For Radiological Image Deblurring with its FPGA Implementation

In this paper a new methodology is presented for restoring radiological images degraded during acquisition and processing. Details of the work, carried out to optimize a neural network (NN) for identifying an autoregressive moving average (ARMA) model used for nonlinearly degraded image restoration, are presented in this paper. The degraded image is expressed as an ARMA process. To improve the ...
